yes, I did it : pilot two planes at the same time :p
The main plane is a FunCub equipped with UavDevBoard and on board tracking video camera.
The second plane is a stock EasyStar, carrying another UavDevBoard, only to send its position.
I took off with the FunCub and put it in autonomous mode. Me having in my hands two RC transmitters, my son kindly launched for me the EasyStar and I drove it all the flight long.
The hardest part was try to stay in the camera turret range. The FunCub speed is set to 50km/h, but even at this speed it is a challenge to follow it and stay in front, with a fully stock EasyStar.
At the end of the flight (FunCub autonomy), my son asked to land his plane :)
I landed the FunCub.
Many thanks to Bill Premerlani, Ben Levitt and Pete Hollands for great continuous support and all the smart UavDevBoard community ...
