Hello,
I'm trying to use William's DCM which was implemented in SF9DOF_AHRS_1_0 and in ArdupilotMega with a 5DOF IMU ( link: http://www.sparkfun.com/products/9268 ) and I have a couple of questions.
How do I calculate these constants: Kp_ROLLPITCH, Ki_

I recently heard a story that went something like this:
A guy had an R/C helicopter with a video camera and an analog video transmitter. He was using carbon blades and was having glitchy video. He switched to wooden blades and the video cleared up

the way it works is: you send a pulse on the leg, then it will send 8 ultrasonic waves, wait for echo, and then output a pulse on the same leg, the length of the pulse defines the distance measurement.

One of my stock Arducopter motors began to lose power when flying the other day, and quickly developed a more serious problem. Now when I give it power from an ESC it twitches back and forth, rarely completing a rotation. I suspected bad sold

Apologies if I'm being dumb and have missed the link to it.

I'm working towards that anxious time of the first flight tests! Has anyone considered (as I am) building some kind of light but strong body for the standard Arducopter, rather like the little Parrot drone has?
