I can only agree with the previous speaker. But still I would like to speak to a closer look. I have a Heli Raptor 50, the old servo unfortunately give up the ghost, with a 3D maneuvers I was able to helli time just as emergency charge. Installed new Serveo ordered and done, I wonder if I have to say I had real doubts about whether he would cope with the rapid load change, but do not see no problem. I have it gewarkt to build the servo apart, and see there are metal gears not installed this cheap plastic which even at the Heliservo was there. All in one I am very satisfied with the power and will leave him there first installed. Very strong buy recommendation.
