I brought 3 dimond 4.4g servos for my schockflyer last week after about 15 flights the rudder servo packed up but i was able to land ok. I replaced it with a satern. Yesterday i was flying my shocky when the aileron servo packed up and it locked up at full throw whilst i was at about 5 feet off the ground which meant my plane fliped along the ground and snapped the fusealage.

Talking to a friend he has had the same problem with dimond servos!!

Dont buy dimond servos if you like your plane!!!
