October 3, 2015Application(s): Tail rotor servo for Align T-Rex 450 Pro FBL
Comments: Have 230 flights on it in my 450, so far without problems. It holds the tail very stable (I'm using an Align 3GX V3.0 as FBL controller). It has survived a number of bad crashes (did have to change gear set twice, but that's all). I have run it on 5.5V and 6V, it works well with both voltages.

October 7, 2012Application(s): tail on 500 efl
Comments: this servo works pretty good, but does not like or function well with gov. set in esc. tried align and castle creations, tail will wag with either gov turned on, changed to ds650 and it is great now.
