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.

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!

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