Hitec "Karbonite" servo's
I think that one report was me, I had a Hitec 475HB on my 27% H9 Edge 540's THROTTLE, with absolutely NO BIND and was flying at 1/4 throttle when the servo shaft broke clean off and killed my motor, luckily I got it down safely and replaced the servo with another one, this time I really sat down and tested it. The other one I gave to my friend and he replaced the broken part.
For the 1/3 H9 Sukhoi I would use Hitec 5945 Coreless Digitals for that all around, there awesome servos with tons of power.
