I hear of drift in the cheap (< $100 ) HH gyros. I need to elaborate on drift behaviour. Mine is a Walkera G006. Here is how it acts :
Setting up for zero creep means having the trim/subtrim centered so the gyro does not receive any turning signal. I do that and get zero creep.
The tail slider will move out to provide the requested turn rate and spring back a little, but still stay extended in the direction of the turn input signal, without creeping unless I hold the stick. Then it will creep. That is normal and called integral windup.
But now when I go to hover, I will always get a slow left (ccw) creep that the gyro will not correct unless I start adding cw trim. The heli will stay stable and hold for the rest of the flight. But, now after I land, the tail slider starts the crunch-creep as if it has cw turn input. (no limit adjustment).
Headspeed, electrical and mechanical adjustments all return the same result, a slow ccw drift , maybe 1 piro/ 20 to 30 seconds.
Do the Telebee and other cheap gyros do this ? I hear this complaint is common to the G006.
Thanx
