Hi nice to know i have a colleague, i'm trying to build a quadrotor with just an Arduino UNO and an old 4ch RC set, i've got the first parts of the hard job almost done, i connected the RC with the UNO and managet to work them together then i wrote the skeleton for the software and a basic open loop trial version
now i'm stuck with the MPU9150 (inertial measurement) but i'll leave it away just to have time to purchase motors and props
