I do not know why this servo has only 4 stars. In my book it is a rock solid servo and has not ever failed me to date. Why pay more for the expensive name brand when you get the same if not better product at a very good price. GREAT SERVO all around.Bought 7 of theses and fitted them to my Black Horse Ryan STA. It's a pretty big plane, but has flown 10 times without any servo problems. Also have them fitted to my Hanger 9 Pulse 40 and no problems. I'll use them again.Very strong and solid, replaced servo in basher bz-444 that went swimming. HIgh quality gears, strong pull and good centering.strong servo, good performance, sounds a little rough, good value.powerful servos and fast response but having problem whith the center position...not always the same...Not bad, but the gear could be more presice.Muy buen servo, excelente torque y relacion calidad precioIt does not move with fever
Return gold !
great servo great price i bought a few more of these coz there so cheap and quality and power is fantasticI got one today. It looks good. I opened it and there is the HT66F03 micro controller inside. However, the control loop is a bit weak and it's just a proportional controller, so you can move the servo a bit before it draws full current. Normal running current is 0.5A and blocking current 2A at 5V. Electronics and mechanics looks good and the gears are all metal and quite strong. The drive mosfets are MT4607, they are rated 5A. This is OK but there are not many reserves.
