I'm working on my first quad.
My project is based on Aeroquad software with some changes :
- Arduino Mega board
- Sensor board is a Sparkfun 9DOF
- Integrated SD logger (blackbox)
- Venus GPS
- Lipo cell monitor
- GPRS telemetry
Frame is :
- 50 cm motor to motor (diagonal)
- brushless motor KD 2213-22T 17A 924Kv
- APC 10x4.7 propellers
- Spektrum 6 channels RC
- Weigth is 1.4Kg
Main idea is to move all sensors calculation to 9DOF board and use main Arduino cpu to perform other tasks.
Yesterday i did my first flight. I've changed Aeroquad source code to read raw sensor data from 9DOF on serial connection. It seems ok, i made many tests with Aeroquad configurator and it works.
Problem is : i'm not able to leave ground because quad flip over at 10cm from ground :(
Ok, i'm a RC newbie but i suspect something in wrong in configuration or software.
I'm just looking for help to make my first, quite stable, fligth and if possible, to compare my Aeroquad configurator data with a working (your) one.
I noticed a problem : in stable mode, with quad on my desk and throttle command only (50%) motors command in not equal on 4 motors but it's different. Is it strange, no ?
Please see attached screenshot of Aeroquad.
Many thanks to anyone who help me :)

check my tutorial on Aeroquad preflight check in the forum ... i think that could be usefull for you .
