It's quite annoying when everyone else in the world has a Turnigy microquad & yours is the only one with an IMU drift issue.

Decoupling the battery from the electronics caused drift in both directions. The only explanation is the battery was preventing drift in its long axis while not affecting drift in its short axis.

The others hard mount their stock KK board with the heavy LCD on the frame & always have the battery underneath.

A laser cutter would make that a lot easier.

Interesting...sounds a bit like the problem I was having with a larger "Frankenstein" quad. I'm getting ready to transfer the electronics and some proper motors to a Flamewheel frame.

Great blogs, by the way. I always enjoy your posts.
