May I first say how indebted I am to the DIY Drones Team for writing the code for the Ardupilot.
Whilst v2.6 worked well on my Easystar when I tried v2.7 I got servo 'twitching' in stabilze mode. Jason thought that this was due to the amount of processing that was now being carried out and that the Ardupilot board was being pushed to the limit. He also mentioned that a new serial driver may help and that this would be incorporated in v2.8. I notice from the SVN that although v2.8 was started there appears to have been no progress since September. I assume that the development teams limited time has been spent on Ardupilot Mega and Adrucopter.
Is the original Ardupilot still being developed or will Ardupiot Mega take over? I am not sure whether I have room for the mega board as I have a camera in the cockpit of the plane and the Ardupilot board fits nicely where the servo cutout is with the Rx on the other side (I have the servos mounted on the rudder and elevator to balance the weight of the camera).
Are there any news about Ardupilot 2.8?
I know its an "old" hardware, but i don't wont to throw it again.
How about the "all in one" Ardupilot with MPU-600 IMU?
