Volantex Ranger 1600 AIR3 iNav setup

Here is how I mounted the AIR3 board in the Ranger.

The board is rotated 180º (facing the tail) making the USB port accessible (Requires board alignment - YAW 180º in iNav configurator) Mounted on a piece of corplast which jams under the wing and is taped to the ply shelf for easy removal.

I drilled a hole in the top of the body to pass the GPS cable through.

Board and servos are powered by a 5V 3A Carbonbird BEC via a power distribution cable.
FrSKY X6R receiver connects to the board by SBUS.

ESC sits on the floor to keep some distance away from the AIR3 and Rx.

The Volantex Ranger 1600 or 757-7 is almost the perfect plane for me. The 2m version 757-8 is just as good and uses the same fuselage.

(Don't confuse this beauty for the terrible 757-4 Mini Ranger 1350mm. Review here)

The 757-7 has a tough plastic fuselage, 1600mm wingspan, no bad habits and excellent quality hardware. It's tough enough, aerobatic enough and glidey enough for my requirements.

Perfect for FPV cruising, aerial video, slope soaring and sport flying.


Currently I have mine setup with a Paris Sirius AIR3 F3 flight control board running iNav 1.7 from Carbonbird, FrSKY X8R reciever and 40A current sensor.

Initially the motor was a Turnigy Aerodrive 2836 1100kV with the stock 8 x 4 prop and 40A ESC
Now changed to an NTM Propdrive 2836 1200kV for better bearings and bolt on prop shaft.

With a 3000mAh 4S battery it cruises around on 3A with 25A flat out.
