Strong servo for it's size

Oct 10, 2019

I installed 4 of these servos in an RCF Edge V3 39"wingspan foamy. The servos are very light and fast. If you need servos that put out over 2 kg of torque this servo is for you. An added bonus is they are below 10g each including wires and connector. There is a considerable amount of slop at center that is magnified when using long servo arms needed in 3d setups. This however doesn't detract from the accuracy when returning to neutral when powered up. It may be due to the tight 2us deadband at center. My aileron servos jittered at neutral but just tapping on the pushrods immediately stopped the jittering. I fabricated a slotted guide that put a little pressure on the pushrod at neutral that worked well and controlled the aileron jittering. I highly recommend this servo for HV set-ups just don't make the mistake of powering them with the full 3s voltage as you will fry your rx and all servos. I made an adapter that powered my receiver and servos through the lipo balancer tap only utilizing 2 cells of my 3s setup. An alternative would be to use a step-down voltage regulator to lower the 3s voltage to 7 to 8 volts.

Works well, but it has the design flaw of not including strain relief for the wires coming out of the case. Had the wires pull straight off the PCB. It's easy to open it up and solder them back on, but I'd expect better from a pricey 9g servo.

I bought 2 of these, one worked fine, the other didn’t work at all, checked the servo and found that the black wire was not connected. Planning to send it back,
