Best FPV RTF Kit for Indoor and Outdoor Flying

About the product

The iFlight Alpha A75 Ana­log Whoop RTF is a well built and fac­to­ry tuned ana­log FPV kit from one of the best devel­op­ers in the hob­by. Includes every­thing you need to fly your drone in first-per­son mode indoors and out­doors. The kit is based on a micro­quad from the “iFlight Alpha” series — Alpha A75, which since its release has man­aged to win recog­ni­tion from both begin­ners and advanced pilots, sub­se­quent­ly becom­ing one of the most pur­chased mod­els. Release date: Feb­ru­ary 2021

Ini­tial­ly, the iFlight Alpha A75 was sold by the devel­op­er exclu­sive­ly in PNP/BNF con­fig­u­ra­tions, which required the user to pre-pur­chase and pair all relat­ed com­po­nents (remote con­trol, FPV gog­gles, bat­tery, mem­o­ry), but now this lit­tle “mon­ster” is also offered in an RTF kit that allows every­one, with­out excep­tion, to get acquaint­ed with this excit­ing hob­by imme­di­ate­ly after unpack­ing. As usu­al, let’s start with the key fea­tures of the Alpha A75 Ana­log Whoop RTF FPV Kit.

Equipment

The Alpha A75 Ana­log Whoop RTF Ana­log Kit will include the fol­low­ing com­po­nents:

1. Drone iFlight Alpha A75
2. Remote con­trol iFlight iF8
3. FPV Gog­gles iFlight FPV Gog­gles
4. HQProp 4‑bladed 40mm Prop Kit (2CW/2CCW)
5. Gem­fan 3‑bladed 40mm Prop Set (2CW/2CCW)
6. iFlight M4 Bal­ance Charg­er
7. 3 × FULLSEND 3S 450mAh 75C Lipo with XT30 con­nec­tor
8. User’s man­u­al

HD equipment

The devel­op­er also offers an HD kit “Alpha A75 HD Whoop w/Polar Nano Vista Dig­i­tal HD Sys­tem BNF”, which essen­tial­ly includes only one quadric. This is because the FPV sys­tem for the HD ver­sion is the top-end dig­i­tal FPV sys­tem “Cad­dx Neb­u­la Nano Kit Vista HD Dig­i­tal Sys­tem” by default, which means that you already have a DJI con­troller and DJI FPV gog­gles with which it is com­pat­i­ble. From which it fol­lows that the HD set, tak­ing into account sep­a­rate­ly pur­chased com­po­nents, is much more expen­sive than the ana­log set, but it’s all worth it.

The first argu­ment is the qual­i­ty of the video link broad­cast at a res­o­lu­tion of 1280 × 720 at 60 fps (ana­logue sys­tem max: 800 × 480p), the sec­ond — for starters, it is worth not­ing the process of pair­ing the com­po­nents of a dig­i­tal sys­tem — it is auto­mat­ic. Fur­ther more! Con­sid­er­ing the fact that today all FPV drones with­out excep­tion are equipped with a dig­i­tal FPV sys­tem, then in the future you will also just have to buy only one quad, since you already have every­thing else. In oth­er words, such a pur­chase for the future.

As for the minus­es, the only nuance of the dig­i­tal sys­tem, so far, is the delay time of no more than 40 ms (ana­log: there is no delay). In fact, this is extreme­ly small and imper­cep­ti­ble to the human brain, but nev­er­the­less it exists — while it exists, after all, we all remem­ber that the tech­no­log­i­cal process does not stand still!

Charger

To charge the bat­tery using the includ­ed charg­er, do the fol­low­ing:

1. Con­nect the bat­tery to the appro­pri­ate ports on the charg­er.
2. Plug in the pow­er cord and wait for the device to boot up.
3. Press and hold the “TYPE/CURR” but­ton for 2 sec­onds to select the bat­tery type (LiPo, LiHV, LiFe; 1–4S).
4. Press the but­ton once to select the charg­ing cur­rent.
5. If all set­tings are cor­rect, the charg­er will auto­mat­i­cal­ly start charg­ing the con­nect­ed bat­tery.
6. Each time you turn on the charg­er, you need to press the but­ton once to unlock the device before it starts charg­ing auto­mat­i­cal­ly.

Developer recommendations

Battery charging

• The devel­op­er notes that the pow­er poten­tial of the bun­dled charg­er is lim­it­ed and allows you to charge LiPo bat­ter­ies no more pow­er­ful than 4S 350 mAh ~ 850 mAh. To charge more effi­cient bat­ter­ies, it is rec­om­mend­ed to use a charg­er — ISDT Q6 Nano.

How to disable Angle-Mode and enable Acro-Mode?

All you have to do is down­load the Betaflight con­fig­u­ra­tor to your com­put­er (Win­dows or Mac), make sure all dri­vers are prop­er­ly installed (a tuto­r­i­al is on the con­fig­u­ra­tor home page), con­nect your drone’s flight con­troller to your com­put­er, and select the Modes/ Modes” (see screen­shot below).

Here is a short video about flight modes and what the whole process looks like:

Next, you can dis­able ANGLE mode com­plete­ly (right-click the “x”) or drag the vir­tu­al slid­er to where you want to acti­vate the AUX switch on your con­trol equip­ment. Don’t for­get to set the cor­rect AUX input as well and test it with­out props!

Firmware update

The devel­op­er strong­ly rec­om­mends down­load­ing the soft­ware only from their GoogleDrive source, where you will also find the cor­rect ver­sion of the Betaflight tar­get soft­ware adapt­ed for each drone series released, which will also be rel­e­vant for down­load­ing and restor­ing the fac­to­ry set­tings of your iFlight BNF drone.

To update the Betaflight firmware, down­load the lat­est Betaflight con­fig­u­ra­tor and flash with the cor­rect Betaflight tar­get. Always use Betaflight tar­get fac­to­ry soft­ware (must have IFLIGHT_ in the name) that comes with user defaults to restore I/O set­tings. You can check the cur­rent ver­sion of Betaflight in the con­fig­u­ra­tor in the Betaflight Con­fig­u­ra­tor sta­tus win­dow or in the com­mand line inter­face.

Video

Visu­al­ly about the Betaflight firmware process:

How to determine the version of your hardware?

If your BNF drone or Flight Con­troller still has fac­to­ry firmware installed, you can also enter the cor­rect Betaflight tar­get in the top left cor­ner of the Betaflight log. In the exam­ple below, the cor­rect tar­get for this par­tic­u­lar flight con­troller would be “IFRC/IFLIGHT_F745_AIO” and can be updat­ed under the “Update Firmware” tab.

Important!

Please make sure you are run­ning the same ver­sion of Betaflight before apply­ing a fac­to­ry dump. Oth­er­wise, update Betaflight to the lat­est ver­sion and change the nec­es­sary set­tings! It is not rec­om­mend­ed to paste old dumps into new ver­sions of Betaflight!

Restoring factory settings

Before per­form­ing a fac­to­ry reset using an iFlight fac­to­ry dump, make sure you have updat­ed or flashed your Betaflight soft­ware. This prompt will auto­mat­i­cal­ly appear after a suc­cess­ful flash and sub­se­quent reboot of your flight con­troller. If it did­n’t, then some­thing went wrong!

• Step 1: Copy the con­tents of *.txt file (GoogleDrive link above)
• Step 2: Open the Betaflight con­fig­u­ra­tor and go to the com­mand line inter­face (at the bot­tom of the left col­umn menu).
• Step 3: Paste into the CLI (com­mand line) and press the Enter key.
• Step 4: Type “save” and press the Enter key to save your set­tings! Fac­to­ry set­tings restored!
• Step 5: To recal­i­brate the gyro­scope in the Betaflight con­fig­u­ra­tor, go to the Set­tings tab.
• Step 6: Set the drone as lev­el as you can and press the “Cal­i­brate” but­ton.

Today it is the best long-play­ing FPV RTF solu­tion for both begin­ners and advanced pilots. The vis­it­ing card of the kit is the iFlight Alpha A75 75mm micro FPV quad, the poten­tial of which has already been appre­ci­at­ed by many users in the hob­by. The drone is per­fect­ly tuned by the devel­op­er in terms of weight / pow­er ratio, which allows it to be rel­e­vant both for dynam­ic flights with ele­ments of acro­bat­ics, and for mea­sured flights with an empha­sis on FPV shoot­ing. It will be more than ever use­ful for all users who are look­ing for the short­est path in the FPV hob­by and at the same time are demand­ing on the qual­i­ty and man­u­fac­tura­bil­i­ty of the prod­uct. Age lim­it 8+.
