The BetaF­PV Cetus Pro FPV Kit is an updat­ed FPV kit for begin­ners, pro­posed by the devel­op­er to replace the pre­vi­ous BetaF­PV Advanced Kit 2. The nov­el­ty includes a new FPV quad mod­el built on a sol­id mono­lith­ic frame with an annu­lar pro­tec­tion of the pow­er plant, which tra­di­tion­al­ly con­sists of four brush­less motors. The drone now sup­ports three flight modes (Normal/Sport/Manual), among which the “Nor­mal” mode, thanks to the addi­tion­al sen­sors involved, pro­vides pre­cise auto-hov­er­ing of the quadric, which novice pilots will appre­ci­ate more than ever. Also includ­ed in the kit were more pro­duc­tive and at the same time light­weight FPV gog­gles and a mod­i­fied con­trol pan­el, which, among oth­er things, was equipped with a built-in capa­cious bat­tery. By tra­di­tion, let’s start with the key fea­tures of the top RTF kit from BetaF­PV.

Below you can read the key infor­ma­tion BetaF­PV Cetus Pro FPV Kit, which will allow you to learn more about the advanced FPV kit, as well as what improve­ments have been imple­ment­ed com­pared to the pre­de­ces­sor BETAFPV Advanced Kit 2.

BETAFPV Cetus Pro

The BETAFPV Cetus Pro is a new micro quad mod­el designed specif­i­cal­ly for the BetaF­PV Cetus Pro FPV Kit RTF. The list of key dif­fer­ences from its pre­de­ces­sor Meteor75 Light includes: a stronger mono­lith­ic frame (with a diag­o­nal size of 78 mm, ver­sus 75 mm of its pre­de­ces­sor), a more pro­duc­tive FPV cam­era, a sen­sor posi­tion­ing sys­tem has been added (pro­vides auto-hold­ing of a posi­tion in Nor­mal mode).

FPV drone Cetus Pro. For a quick entry into the hobby

It is equipped with a pro­pri­etary BT2.0 type con­nec­tor, which has proven to solve most of the prob­lems of the PH2.0 con­nec­tor com­mon among micro drones, includ­ing the prob­lem of volt­age drop / draw­down.

FPV drone Cetus Pro. For a quick entry into the hobby

BT2.0 connector

The BT2.0 type con­nec­tor is a rev­o­lu­tion­ary type of con­nec­tor for 1S micro drones, devel­oped by BETAFPV engi­neers as a high­ly effi­cient alter­na­tive to the obso­lete PH2.0 con­nec­tor. Pro­vides a sig­nif­i­cant dif­fer­ence in pow­er effi­cien­cy com­pared to its pre­de­ces­sor. The devel­op­er notes the fol­low­ing advan­tages of the BT2.0 con­nec­tor:

  • Effec­tive­ly reduces the inter­nal resis­tance of the con­nec­tor by upgrad­ing the crimp con­tacts to 1mm banana con­nec­tor and increas­ing its cross-sec­tion­al area.
  • Solves the prob­lem with a drop / volt­age drop. Dis­charg­ing LiPo bat­tery with BT2.0 con­nec­tor becomes more effi­cient. Pilots can enjoy longer flight times with­out the fear of over­charg­ing their bat­ter­ies.
  • The bat­tery with BT2.0 con­nec­tor has sta­ble current/voltage out­put and high effi­cien­cy. All 1S brush­less drones get pow­er­ful and flaw­less per­for­mance from this type of bat­tery.
  • Ide­al for Emax Tiny­hawk series quads as the con­nec­tor deliv­ers con­sis­tent and con­sis­tent pow­er, result­ing in bal­ance in dynam­ics and longer flight times.
  • Com­pared with PH2.0 crimp con­tacts, BT2.0 con­nec­tor is more durable, it can out­put more cur­rent for the same capac­i­ty and deliv­er much more pow­er.

Comparison chart

Below you can see a com­par­i­son graph from the devel­op­er between BETAFPV 1S 450mAh 30C bat­ter­ies with BT2.0 con­nec­tor and Emax 1S 450mAh 80C bat­ter­ies with PH2.0 con­nec­tor. In this test, the dis­charge cur­rent is 11A. Obvi­ous­ly, a bat­tery with BT2.0 has a longer dis­charge time and improved volt­age drop, which results in bet­ter flight per­for­mance.

FPV drone Cetus Pro. For a quick entry into the hobby

Power potential

The devel­op­er equipped the quad with a high-per­for­mance Lite 1–2S Pro flight con­troller with built-in 12A speed con­trollers, which in turn work in tan­dem with the time-test­ed 1102 18000KV brush­less motors and 40mm 3‑blade pro­pellers. At the out­put, the Cetus Pro pow­er plant pro­vides, with­out exag­ger­a­tion, expo­nen­tial pow­er and flight maneu­ver­abil­i­ty for the occu­pied UAV niche.

FPV drone Cetus Pro. For a quick entry into the hobby

Altitude hold function

Thanks to the built-in sen­sor sys­tem (opti­cal sensor/barometer/laser), this quad­copter can auto­mat­i­cal­ly hold the alti­tude when the pilot’s hands do not touch the con­trol sticks. The sen­sor sys­tem pro­vides accu­rate and con­fi­dent posi­tion­ing, mak­ing this mod­el sta­ble even in tight fly­ing con­di­tions. Alti­tude Hold is only avail­able in N (Nor­mal mode).

FPV drone Cetus Pro. For a quick entry into the hobby

self defense

The devel­op­er added a self-pro­tec­tion func­tion to the quadric, which auto­mat­i­cal­ly acti­vates an emer­gency land­ing in the event of a loss of com­mu­ni­ca­tion or insuf­fi­cient volt­age. It will also auto­mat­i­cal­ly stop the motors when it hits an object.

FPV drone Cetus Pro. For a quick entry into the hobby

Turtle Mode

If the quadric turned over, then it is not at all nec­es­sary to run towards it in order to turn it into a fly­ing state. For this case, the devel­op­er added the “Tur­tle or Tur­tle mode” mode to the drone sys­tem, which allows you to remote­ly turn it over by switch­ing the tog­gle switch on the con­trol pan­el. It is also not­ed that tur­tle mode will not work effec­tive­ly if some­thing is stuck in the motor/guard ring. In this case, it is rec­om­mend­ed to imme­di­ate­ly exit the tur­tle mode using the SD tog­gle switch on the con­trol equip­ment. Learn more about Tur­tle Mode in the Advanced Set­tings sec­tion below.

FPV drone Cetus Pro. For a quick entry into the hobby

Flight modes

There are three modes avail­able N mode (Nor­mal mode)/S mode (Sport mode)/M mode (Man­u­al mode), which smooth­ly reveal the flight poten­tial of the quadric and thus ful­ly meet the needs of pilots with dif­fer­ent lev­els of train­ing. In oth­er words, whether you’re an expe­ri­enced FPV pilot or a com­plete begin­ner, the Cetus Pro FPV kit will help any­one fly con­fi­dent­ly from day one.

You can switch between these modes with just one SB tog­gle switch on the con­trol equip­ment (see the sec­tion below “Assign­ment of con­trols”). Mean­while, all these modes sup­port 3 speed modes SLOW(Slow)/MID(Medium)/FAST(Fast). To change the dynam­ics of the flight, it is enough to switch the SC tog­gle switch on the remote con­trol to the desired posi­tion:

FPV drone Cetus Pro. For a quick entry into the hobby

  1. N mode (Normal mode)

    — in this mode, the aux­il­iary hold posi­tion func­tion is active. The quad­copter will main­tain a fixed alti­tude when both joy­sticks are in the cen­ter posi­tion. The flight angles are min­i­mal, the response to the move­ment of the con­trol sticks will be smooth. When the mode is acti­vat­ed, the dis­play of the FPV gog­gles will show “N MODE”. The mode is rel­e­vant for begin­ners. The devel­op­er reminds that the sen­sor sys­tem respon­si­ble for fix­ing the posi­tion of the copter oper­ates in the height range from 0.3–3 meters.

  2. S mode (Sport mode)

    — in this mode, the posi­tion hold aux­il­iary func­tion is dis­abled. The pilot will need to con­trol the flight alti­tude with the throt­tle stick (default left stick) and the hor­i­zon­tal posi­tion with the direc­tion stick (default right stick). The flight angles will become larg­er, the response to the move­ment of the con­trol sticks will be sharp­er. When the mode is acti­vat­ed, the dis­play of the FPV gog­gles will show “S MODE”. This mode fea­tures more dynam­ic and com­plex con­trols and is suit­able for the expe­ri­enced pilot.

  3. M mode (Manual mode)

    — in this mode, the posi­tion hold aux­il­iary func­tion is dis­abled. The pilot will need to man­u­al­ly con­trol the height and posi­tion of the quadric. Acro­bat­ic flight becomes avail­able. This mode fea­tures even more com­plex con­trols and requires a lot of prac­tice to mas­ter.

FPV drone Cetus Pro. For a quick entry into the hobby

Changing speed modes

The quad­copter flight speed thresh­old can be changed in all three of the above flight modes using the SC switch on the con­trol pan­el:

FPV drone Cetus Pro. For a quick entry into the hobby

On/Off touch system

In N‑mode, the quad­copter posi­tion hold assist func­tion is enabled by default, thus pro­vid­ing a novice pilot­ing aid. You can dis­able this fea­ture if nec­es­sary. To disable/enable the touch hold posi­tion func­tion, do the fol­low­ing (use the remote con­trol to access and nav­i­gate the OSD menu of the FPV gog­gles):

FPV drone Cetus Pro. For a quick entry into the hobby

  1. Turn on the remote, FPV quad and FPV gog­gles.
  2. From the main menu of the FPV gog­gles, select “CONFIG” and enter the “CONFIG” menu as shown below.
  3. Select “OPF” and change “ON” to “OFF” (Dis­able Touch Positioning)/ON (Enable Touch Posi­tion­ing), then select “BACK” to exit the “CONFIG” sub­menu.
  4. Select “SAVE” in the “MAIN” menu to exit the OSD set­tings menu.

For more details on how to inter­act with the OSD, see the “VR02 FPV Goggles/On Screen Dis­play (OSD)” sec­tion below.

FPV drone Cetus Pro. For a quick entry into the hobby

Charger

Accord­ing to the stat­ed spec­i­fi­ca­tion, each drone bat­tery pro­vides 4–5 min­utes of smooth flight. A low bat­tery will be indi­cat­ed by a warn­ing in the OSD inter­face “LOW VOL”, and the LED on the quad­copter itself will flash red.

FPV drone Cetus Pro. For a quick entry into the hobby

Charging steps are as follows:

  1. Con­nect the charg­er to the Type‑C port using the includ­ed USB cable.
  2. Con­nect one or two bat­ter­ies to the port to the right of the charg­er. The red charg­ing indi­ca­tor will indi­cate the charg­ing process. Charg­ing is com­plete when the charg­er LED turns green.

Two bat­ter­ies can be charged at the same time. Charg­ing a ful­ly dis­charged bat­tery takes about 20 min­utes. If the bat­tery is insert­ed into the “TEST” port, and the USB cable is not con­nect­ed to the charg­er, the charg­er works as a volt­meter, through which you can mea­sure the cur­rent bat­tery charge lev­el, where a read­ing of 4.30V indi­cates a ful­ly charged bat­tery, and 3.30V indi­cates a low lev­el charge.

VR02 FPV Goggles

FPV drone Cetus Pro. For a quick entry into the hobby

The VR02 FPV Gog­gles are the sec­ond iter­a­tion of FPV gog­gles specif­i­cal­ly designed for the begin­ner audi­ence, fea­tur­ing sim­pler and more intu­itive func­tion­al­i­ty than the advanced ver­sions. Like its pre­de­ces­sor, it is built on a 4.3‑inch high-bright­ness HD LCD dis­play with a res­o­lu­tion of 800 × 480 pix­els, paired with a high-qual­i­ty lens with a trans­paren­cy of 92%, pro­vid­ing a 2.8x increase in FPV images with­out dis­tor­tion and blur. Unlike its pre­de­ces­sor, VR02 received a lighter body, as well as built-in high-qual­i­ty 5.8 GHz anten­nas with a gain. gain of 14 dBi, which allows you to get sta­ble and clear images even at max­i­mum flight dis­tances.

Turning on the FPV Headset

To turn on the FPV head­set, do the fol­low­ing:

FPV drone Cetus Pro. For a quick entry into the hobby

  1. Slide the pow­er switch to the right. The screen will light up and the FPV gog­gles will turn on.
  2. Press and hold the “S” but­ton for 1 sec­ond to turn on the quick search func­tion of the oper­at­ing fre­quen­cy. After 3 sec­onds, a beep will sound and the glass­es will dis­play a live video stream, indi­cat­ing the end of the search. VR02 FPV Gog­gles are ready to go.

On Screen Display (OSD)

After search­ing for a fre­quen­cy, the flight infor­ma­tion and the FPV image broad­cast from the quadric will appear on the dis­play. All of this flight infor­ma­tion is part of the on-screen dis­play (OSD). In the flight ver­sion of the OSD dis­play, it looks like this:

FPV drone Cetus Pro. For a quick entry into the hobby

Tak­en as a whole, the OSD is a set of oper­at­ing inter­faces designed to change the con­fig­u­ra­tion of the quad­copter.

How to interact with OSD

To enter the OSD menu, you need to turn on the con­trol equip­ment, quadric (with­out start­ing motors) and FPV gog­gles. Then, on the remote con­trol, move the con­trol sticks to the posi­tions as shown below. The throt­tle stick (default left stick) moves left cen­ter, and the direc­tion stick moves up cen­ter:

  • Step 1.

    Set the throt­tle stick (default left) and four switch­es (SB/SA/SC/SD) on the remote con­trol radio to the low­est posi­tion. Press and hold the pow­er but­ton on the remote con­trol for 5 sec­onds until it beeps three times, then release. The remote con­trol’s pow­er indi­ca­tor will flash red quick­ly and then change to blue to indi­cate that the pow­er is on.

  • Step 2:

    Install the bat­tery in the bat­tery hold­er under the quad­copter. Make sure the bat­tery pow­er cable and quad­copter pow­er cable are on the same side. Con­nect the quad­copter to the bat­tery, then place the quad­copter on a hor­i­zon­tal sur­face. Wait 3–5 sec­onds until its sta­tus LEDs change from flash­ing blue to sol­id blue. This means that the ini­tial­iza­tion of the quad­copter is com­plet­ed and the quad­copter is suc­cess­ful­ly con­nect­ed to the remote con­trol.

  • Step 3:

    Move the SA switch up to turn on the quad­copter. The throt­tle stick (left by default) must be in the low­est posi­tion, oth­er­wise the quad­copter will not turn on! The motors will start spin­ning slow­ly. Move the SA switch down, the motors will stop.

Com­plet­ing these steps con­firms that the quad­copter and remote con­trol are work­ing prop­er­ly, so you can pro­ceed to fly.

Piloting

Start the drone’s motors (Step 3). The motors will rotate at low speeds, but the quad itself will not take off. Slow­ly move the throt­tle stick (left by default) up to lift the air­craft into the air. In N‑mode, the quad will hold posi­tion auto­mat­i­cal­ly even if the pilot releas­es the con­trol sticks. Fur­ther details on the pur­pose of each of the sticks:

Landing

Land in a sta­ble and smooth descent. After the quad has land­ed, turn off the motors by switch­ing the SA-tog­gle switch on the con­trol pan­el, as shown below:

FPV drone Cetus Pro. For a quick entry into the hobby

Dis­con­nect and remove the bat­tery from the quad­copter. A long press of the pow­er but­ton on the remote con­trol will turn it off after three beeps.

LED backlight status

Drone

At the bot­tom of the drone, there are two RGB LEDs that reflect the cur­rent state of the drone:

Sound accompaniment

In addi­tion to LED sta­tus indi­ca­tion, the so-called buzzer is built into the con­sole, by the sound of which the pilot can deter­mine the oper­at­ing state of the con­trol equip­ment:

FPV drone Cetus Pro. For a quick entry into the hobby

Advanced settings

Addi­tion­al­ly, in the drone sys­tem, the devel­op­er has laid down a num­ber of advanced set­tings that will be rel­e­vant for solv­ing some prob­lems that arise dur­ing oper­a­tion.

Turtle mode

When the quad­copter hits the ground and rolls over, you don’t have to run towards it. To turn it over, it is enough to acti­vate the “Tur­tle mode / Tur­tle mode” by switch­ing the tog­gle switch on the con­trol pan­el. To acti­vate tur­tle mode, do the fol­low­ing:

FPV drone Cetus Pro. For a quick entry into the hobby

  1. Move the SD switch on the remote con­troller from the bot­tom posi­tion to the top posi­tion. The FPV gog­gles will dis­play the logo tur­tles».
  2. Now move the direc­tion stick (right stick by default) in any direc­tion. The motors of the quadric will begin to rotate and it will inde­pen­dent­ly turn over to the flight posi­tion.
  3. Flip the SD switch down to turn off Tur­tle mode. Start the engines and con­tin­ue fly­ing.

Note: Tur­tle mode is suit­able for flat ground. The devel­op­er does not rec­om­mend acti­vat­ing it on grass or fab­rics with a long pile, oth­er­wise, with a greater degree of prob­a­bil­i­ty, the oper­a­tion of the motors will be lim­it­ed or blocked alto­geth­er, which will lead to the fail­ure of the pow­er plant.

Re-pair devices

If the quad­copter and remote con­trol can­not con­nect suc­cess­ful­ly, the pilot may need to re-pair/­pair the devices. Typ­i­cal­ly, this can hap­pen when replac­ing the elec­tron­ic com­po­nents of the quad­copter dur­ing main­te­nance, as well as as a result of upgrad­ing the radio trans­mit­ter of the remote con­trol. To link devices, do the fol­low­ing:

FPV drone Cetus Pro. For a quick entry into the hobby

  1. Turn on the quad­copter and wait for its sys­tem to ful­ly boot.
  2. Using a screw­driv­er, light­ly press the but­ton on the quad­copter, and the sta­tus LEDs on the quad­copter will change col­or to green and start blink­ing.
  3. Turn on the remote con­trol and wait for the sys­tem to boot com­plete­ly.
  4. Light­ly press the BIND but­ton on the back of the remote con­trol with a screw­driv­er. The pow­er indi­ca­tor will blink red.
  5. If the device pair­ing process is suc­cess­ful, the quad­copter sta­tus LEDs will change to blue.

Note: Rebind­ing the remote con­trol radio trans­mit­ter to the air­craft may not com­plete suc­cess­ful­ly after press­ing the BIND but­ton on the remote con­trol radio trans­mit­ter once. In this sit­u­a­tion, the pilot must press the BIND but­ton a sec­ond time to com­plete the bind­ing.

Gyro calibration

Take­offs, land­ings, minor crashes/accidents dur­ing the oper­a­tion of the quad­copter inevitably have a neg­a­tive impact on the oper­a­tion of the gyro­scope. Incor­rect oper­a­tion of the gyro­scope leads to the fact that the quadro­copter in flight will spon­ta­neous­ly tilt/shift to one side. To fix this, the quad­copter gyro­scope can be cal­i­brat­ed. The steps are:

FPV drone Cetus Pro. For a quick entry into the hobby

  1. Turn on the quad­copter, remote con­troller and FPV gog­gles. Make sure the con­nec­tion is estab­lished.
  2. Place the quad­copter on a hor­i­zon­tal sur­face.
  3. Enter the OSD menu of the quad­copter (refer to the On-Screen Dis­play (OSD) sec­tion).
  4. From the main menu, select CONFIG, then CALI.
  5. Move the direc­tion stick (right stick by default) to the right to start the lev­el cal­i­bra­tion mode. The quad­copter LED flash­es blue.
  6. The end of the cal­i­bra­tion process will be indi­cat­ed by an OK mes­sage and the air­craft LED will change from flash­ing blue to sol­id blue. The pilot can exit the OSD.

Remote Control Calibration

After repeat­ed use, or if the remote con­trol has been sub­ject­ed to phys­i­cal impact, the con­trol equip­men­t’s sticks may no longer read the cor­rect read­ings, which may require recal­i­bra­tion. To do this, do the fol­low­ing:

FPV drone Cetus Pro. For a quick entry into the hobby

  1. After turn­ing on, press the SETUP but­ton on the back of the remote con­trol, when pressed, the con­trol equip­ment will emit two beeps, and the LED indi­ca­tor around the pow­er but­ton of the remote con­trol will flash red twice quick­ly. The remote con­trol has entered cal­i­bra­tion mode.
  2. Move the throt­tle stick (default left stick) and direc­tion stick (default right stick) to the cen­ter posi­tion. Press the SETUP but­ton again and wait until the remote con­trol beeps three times. The red LED will flash twice quick­ly. This means that stick cen­ter data has been received.
  3. Slow­ly move the throt­tle (left stick by default) and direc­tion (right stick by default) stick twice in a cir­cle to their max­i­mum posi­tions (once coun­ter­clock­wise and once clock­wise), then press the SETUP but­ton again. The remote con­trol will beep for about 3 sec­onds and the LED will stop flash­ing. Cal­i­bra­tion com­plet­ed suc­cess­ful­ly.

OPF control

In flight mode “Nor­mal; Nor­mal mode”, Opti­cal Flow Posi­tion­ing (abbr: OPF) is enabled by default, which auto­mat­i­cal­ly holds the posi­tion of the copter, thus mak­ing it eas­i­er for a novice user to take the first steps in learn­ing to fly. To enable/disable the OPF func­tion, do the fol­low­ing:

FPV drone Cetus Pro. For a quick entry into the hobby

  1. Turn on the quad­copter, remote con­troller and FPV gog­gles. Make sure the con­nec­tion is estab­lished.
  2. Enter the OSD menu of the quad­copter (refer to the On-Screen Dis­play (OSD) sec­tion).
  3. From the main menu select CONFIG and go to the CONFIG menu as shown below.
  4. Select OPF and change the val­ue next to the func­tion name: OFF (dis­able positioning)/ON (enable posi­tion­ing), and then select BACK to exit the CONFIG sub­menu.
  5. Then select SAVE from the MAIN menu to exit the OSD set­ting inter­face.

Note: The OPF func­tion of the Cen­tus Pro quadric is built on an opti­cal sen­sor, the cor­rect oper­a­tion of which depends entire­ly on opti­mal light­ing.

TOF control

In flight mode “Nor­mal; Nor­mal mode”, the laser height detec­tion func­tion is dis­abled by default. Enabling this func­tion can make the hov­er­ing of the air­craft more accu­rate, and it can also main­tain a fixed rel­a­tive height in rela­tion to the ground and/or ground objects, thus allow­ing the air­craft to auto­mat­i­cal­ly rise in height in flight when the ground is uneven or obsta­cles, there­by mak­ing it eas­i­er to for a begin­ner, the first steps in learn­ing to fly. To enable/disable the TOF func­tion, do the fol­low­ing:

FPV drone Cetus Pro. For a quick entry into the hobby

  1. Turn on the quad­copter, remote con­troller and FPV gog­gles. Make sure the con­nec­tion is estab­lished.
  2. Enter the OSD menu of the quad­copter (refer to the On-Screen Dis­play (OSD) sec­tion).
  3. From the main menu select CONFIG and go to the CONFIG menu as shown below.
  4. Select TOF and change the val­ue next to the func­tion name: OFF (dis­able the function)/ON (enable the func­tion), and then select BACK to exit the COFIG sub­menu.
  5. Then select SAVE from the MAIN menu to exit the OSD set­ting inter­face.

  • Safe flight (frame with ring pro­tec­tion) Indoor and out­door
  • Fac­to­ry tuned to rac­ing stan­dard
  • Pow­er­ful B/C motors
  • Con­trol­la­bil­i­ty

Minuses

  • No built-in DVR
  • FPV cam­era (good FPV pic­ture only with opti­mal light­ing)

A high-qual­i­ty iter­a­tion of the pre­vi­ous top FPV kit, which received a num­ber of notice­able improve­ments affect­ing both the prod­uct itself and its flight qual­i­ties. In par­tic­u­lar, the impact resis­tance of the main frame has been improved. At the same time, it has become not tougher, but more flex­i­ble, thanks to which it is able to for­give the numer­ous acci­dents of a novice pilot with­out fear of harm, which is also an impor­tant fac­tor. Improved aspects affect­ing the com­fort when wear­ing FPV gog­gles, the head­set has become lighter and now it is com­fort­able to pilot in it (unlike the pre­vi­ous head­set, the area around the nose no longer cre­ates dis­com­fort). The con­trol equip­ment received a built-in bat­tery, which pro­vides eight hours instead of three hours.

Field tests have shown that the qual­i­ty of com­mu­ni­ca­tion and the trans­mit­ted FPV pic­ture have become notice­ably bet­ter. Pilot­ing in first-per­son mode at max­i­mum dis­tances, or through sev­er­al rooms, is much bet­ter than the poten­tial of its pre­de­ces­sor. The call­ing card of the quadric is the added posi­tion hold func­tion imple­ment­ed for this mod­el through a pair of sen­sors. This is not to say that the func­tion works per­fect­ly, but it will def­i­nite­ly come in handy for the most inse­cure pilots. The bun­dled pow­er sup­ply pro­vides about 3 min­utes of flight in the “throt­tle to the floor” mode and about 4.5 min­utes in the “cruise” mode, and there­fore we strong­ly rec­om­mend that you pur­chase addi­tion­al bat­ter­ies (at least four more bat­ter­ies).

The main dis­ad­van­tage of the extend­ed kit is the lack of a built-in video recorder (DVR) in FPV glass­es. An FPV cam­era is good only as long as the ambi­ent light­ing is opti­mal, so the less light, the more noise on the screen of the FPV head­set. Due to its light weight and frame design, the quad does not like windy con­di­tions, but due to the poten­tial of brush­less motors and advanced pilot­ing expe­ri­ence, it still allows you to con­fi­dent­ly cope with the pres­ence of wind.

To sum­ma­rize, the updat­ed BetaF­PV Cetus Pro FPV kit is a well-exe­cut­ed and fin­ished prod­uct. Includes all the nec­es­sary com­po­nents for the safe oper­a­tion and trans­porta­tion of the copter. Extreme­ly easy to use. Does not require pre-con­fig­u­ra­tion — charged and flew. First of all, the kit is designed for entry-lev­el users. Due to its inher­ent poten­tial, it is excel­lent as a sim­u­la­tor for prac­tic­ing pilot­ing skills in pro­fes­sion­al modes (Acro/Manual). Age lim­it 8+.

FAQ

Q. How to change propellers?

A. Use the wrench pro­vid­ed to remove the pro­pellers. Grab the motor when remov­ing the pro­pellers. This approach will elim­i­nate the defor­ma­tion of the frame from over­volt­age.

The kit includes 4 spare pro­pellers: two CW-direc­tion pro­pellers (Clock­Wise; clock­wise) and two CCW-direc­tion pro­pellers (Coun­terСlock­Wise: anti-clock­wise). CW pro­pellers spin clock­wise. They are mount­ed on the rear left or front right motor. CCW pro­pellers spin coun­ter­clock­wise. They are mount­ed on the rear right or front left motor.

Q. How to fix quadcopter drift when piloting in Normal/Normal flight mode?

A. In flight mode “Nor­mal; Nor­mal mode”, the opti­cal flow posi­tion­ing func­tion (OPF) of the Cetus Pro quadro­copter is enabled by default. How­ev­er, it is worth con­sid­er­ing the fact that the OPF func­tion is built on an opti­cal sen­sor, the cor­rect oper­a­tion of which entire­ly depends on the com­pli­ance of the envi­ron­ment with opti­mal oper­at­ing con­di­tions. In par­tic­u­lar, opti­mum illu­mi­na­tion must be ensured, and the ground sur­face must also be dis­tin­guish­able/non-homo­ge­neous. Oth­er­wise, the quad­copter may drift or be dif­fi­cult to con­trol. The fol­low­ing are com­mon unsat­is­fac­to­ry oper­at­ing con­di­tions under which the air­craft with the opti­cal sen­sor enabled (OPF func­tion) will behave incor­rect­ly in pilot­ing:

FPV drone Cetus Pro. For a quick entry into the hobby

  • Dark homo­ge­neous envi­ron­ment
  • Above the sur­face of the water
  • Smooth or plain sur­face

If the quad­copter needs to fly in unsat­is­fac­to­ry envi­ron­men­tal con­di­tions, the opti­cal flow posi­tion­ing func­tion (OPF) can be dis­abled, which will pre­vent auto­mat­ic posi­tion hold­ing. This will require the best pilot­ing skills from the user.

Sim­i­lar restric­tions apply when the laser alti­tude detec­tion (TOF) func­tion is enabled, so try to avoid the fol­low­ing unsat­is­fac­to­ry oper­at­ing con­di­tions:

  • Envi­ron­ment with strong sun­light or with clear changes in light and dark
  • Homo­ge­neous black earth
  • High­ly reflec­tive ground sur­face, etc.

To enable/disable the Posi­tion­ing Func­tion (OPF) or Laser Height Detec­tion Func­tion (TOF), see the Advanced Set­tings sec­tion above.

Make sure that the bot­tom of the sen­sor is not blocked by any­thing, and that there is no dirt or dust on its sur­face, which may affect the accu­ra­cy of oper­a­tion. If the flight assist func­tion is not work­ing prop­er­ly, the sen­sor should be wiped down before the quad is put into oper­a­tion.

Q. How can I connect the remote control to a computer for virtual piloting with an FPV simulator?

A. The Lite Radio 2 SE remote con­trol sup­ports most FPV sim­u­la­tors on the mar­ket thanks to its uni­ver­sal con­fig­u­ra­tion. To con­nect the con­trol equip­ment to the com­put­er, do the fol­low­ing:

FPV drone Cetus Pro. For a quick entry into the hobby

  1. Turn on the remote and wait until the blue LED lights up.
  2. Con­nect the remote con­trol to the PC using the sup­plied USB‑A ⟷ USB‑C cable.
  3. The required dri­ver will be installed auto­mat­i­cal­ly. A win­dow will appear con­firm­ing suc­cess­ful instal­la­tion.
