Was very disappointed by this nugget http://diydrones.com/forum/topic/show?id=705844%3ATopic%3A25130
which killed our hopes for EasyStar ecstacy. So many junk parts are emerging from Vicacopter that a throwaway UAV based on the EasyStar & GPS was a goal. We now have 2 IDG300 gyros, 1 PG-03 gyro, & 2 GPS modules.
There is an anecdote here http://www.rcgroups.com/forums/showthread.php?t=663091
which describes stabilizing the EasyStar with a yaw gyro. The yaw gyro stabilizes roll by correlating roll & turn rate. Release rudder input and the gyro defeats the turn by centering the roll.
Not sure if anything can be done for pitch stabilization.
