I have been using these on some 48" foam aerobats, and a 450 size heli for a couple years now.
I've only had one go bad on the heli, and it failed by getting jitters, ie...not a catastrophic crash. My heli flying is scale 2d, not wild, so your results might vary.
My foam aerobat IS WILD, and I've crashed the plane but never damaged a servo.
As someone else mentioned, they do seem to have a unique post size so only the arms that come with it fit properly. (Posted on 1/7/2016)
I have 2 of these in my Custom F-27C Stryker that have over 200 flights and several hard crashes that show no signs of wearing out. Just purchased 4 more for a 48" Edge 540 I am turning into a float plane. My only gripe is the output shaft splines are an odd size, so finding different servo arms has been tough.

This servo isn't the greatest, but it does work. I am not sure of the durabilty or lifespan but I have been using it on a Tricopter tail as a rudder servo with no problems so far. When it croaks, I'll just toss it and buy another (Posted on 4/3/2013)
I use these servo's in all my parkflyers, profile 3D planes and combat wings. never had issues with them so far! perfect servo for the Sabre 35. plenty (Posted on 2/28/2013)
