I recently received a package from UK with a BNF IFly4S. I connected it’s flight controller to a Walkera Devo RX701 2.4Ghz 7ch Receiver (Walkera-Parts-RX701) in order to be able to control it with my DEVO7 radio, best radio I have so far. Connection was not difficult although it took a while as it was my first connection between a receiver and a flight controller, ever.

The flight controller was then connected to a PC with Ifly Tools installed and calibration of the radio was done. Had a few problems on this one, but eventually succeeded also thanks to a couple of youtube videos that you will find in the specific models section.

Then comes the first flight test. Will it work? Please find out in the video below.
