i have the cheaper EPP black type 12x45 props from jDrones,
as i mounted one of the on the motor, it's clear it needed to be balanced.
as a temporary method i put electrical tape on top of one of the prop's sides,
it did the job and i could reduce the

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_

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
