Wierd servo

[rcthrasher]

Hi all,

Took my heli up today- flying perfectly, then for some reson the elevator comes back fully with no input from the transmitter, it lasted for about 0.5 seconds but still frightened the life out of me. Anybody got any ideas why this would have happened?

Radio gear was a DX7 and Ar6200

Hello mate im no expert but my 500 had gone in 4 times now with total loss of control in ideal 1 or 2, turns out my main bearing are f----- big time, this is making some sort of interferance to the electronics. Anyway not sure if its the same for you but have a check. U need to take them right out to check them, good luck

The servo's are Futaba 9255's. It only happened once in the day and there was no sign of it any other time. The heli was going flat out down the strip and just decided to pull back. I will check both the main bearing and the servo gears. I will also check anything else people come up with.
