My friend has a Falcon se and he has a 50 size engine in it and a 502 gyro. The heli was a nice flying machine untill one day when he moved the 9253 tail servo to the boom and installed a new carbon tail boom, now the tail servo is like glitching really bad. I wouldn't really call it a wag. We have tried everything we can think of and nothing. We have changed the boom back to aluminum, moved the servo back to the front, changed the gain speed's. The only thing I can think it is, is maybe the tail servo has crapped out on him or the gyro has. I thought I would ask and see if anyone could answer the question before I had him buy a new servo and gyro.

Thanks,
Jason

Well, we tried taking apart the servo for any loose wires it is solid. The twitching seems to be getting worse. Has anyone had problems with this combination ( 9253/ 502)? The twitch is a side to side movement, While it was hovered we were able to get close enough to the side to see the servo was actually jumping as much as a 1/4" in both directions. The twitching starts as the heli gets light on its gear before it actually lifts off, and continues at a sporadic rate until it is back on the ground again.
