Default 2721 servo gear problem

I'm using 2721 servos and I just had my second gear failure.
It looks like it's a two piece gear and where the two pieces are pressed together it's spinning. Is this a common problem with this servo?
I'v been lucky and found both on the ground.
The first one was on one elevator half and tonight on one aileron.
They are on a H9 extra 330l (dual servo ailerons), are these a good choice for this plane.
Thank's for any help!!!

I've only heard of this once before, and that was someone that posted a similar question here on RCU some time ago. We have not seen a servo here with the problem you are describing. If you would, please send them in to us and let us check them out. If you would like more information on this, please give one of our techs a call at 877-504-0233.

Default 2721 gears

I have had a problem with the 2721 gears as well, not sure I still have the gear set around though. It was the exact failure you mentioned. My problem arose shortly after I had a prop strike that splintered the wood prop on T.O. roll. I aborted but the ailerons really took some wicked vibration due to the prop. Shortly after I notice ailerons were less sensitive than normal and eventually the gearset on one servo was slipping on the ground.
I really can't blame JR for that one, otherwise they have held up fine on my 29% Edge.
