maple pilot is a new auto pilot i am working on ,i have a working prototype and am working on porting the APM code from diydrones.com . here are the hardware features :
ADXL345 3 axis accelerometer
IMU3000 3 axis gyro
BMP085 absolute pressure
MP3V500 differential pressure
HMC5883L 3 axis magnetometer
ublox lea-5h GPS
SDcard
so far I have the DCM algorithm working and printing data to sd card
you can get the latest code here http://code.google.com/p/maplepilot/
it will be a whole new board , it will have a fail safe mux http://diydrones.com/profiles/blog/show?id=705844%3ABlogPost%3A47351
like this one
8 pwm outputs for servos
I plan on integrating the sparkfun IOIO http://www.sparkfun.com/products/10748
and i will be adding some 12bit magnetic encoders for gimbal control
i would make a shield but things can get very tight space wise and you can have a huge amount of vibration with gas engines and helis . the circuitry needs to be as solid as possible .

hey, nice idea, I did something similar a while ago and I called leafpilot, it flew ok but used analog sensors and had no mag, same as old ardupilot and used gps track, planes only. Honestly, its not the right code base to start with, as I think you will spot as you progress, its ugly and you already spotted an rtos would be nice.
I will try and help you where I can but currently playing with the movecopter stuff. Openpilot is sooo much better than anything ardupilot, light years ahead of it, very solid code and the PSX Move is only $50 with a 9DoF.
Another project well worth looking at is gluonpilot its Pic based and there hardware is totally closed which is a negative but simple to port to the STM32. Quality code and flight tested, I have one and happy with the performance, again light years ahead of anything diydrones.
A word of warning, if you try and do this commercially and use any code from diydrones, you will be pressured to have them sell it, if you do not play ball, your posts on their site will often not be approved and other such nonsense.

I remember some previous posts about making an autopilot using STM32F103, and I think this is there work:

@ leafpilot
ya I'm very used to how things work at diydrones. I'm a long time mod there. you're absolutely right about the code .was really only thinking of using it as a way to get something working quickly then building a much more solid base for the code. dma, rtos, interupts etc. I made an AP using a netburner mod5213 used a linear kalman filter but hated the license etc for the hardware and ide .ill have to checkout glueon and openpilot code. thanks for the tip. if you're interested I could send you one of the prototypes ill be fabricating over the next couple weeks. I specialize in design and fabrication of airframes .you can see a lot of the stuff I've done on my DIY profile
