Very Good Servos

Jun 20, 2021

Great servos. Smooth action, easily hits rated torque, multiple voltage ranges, etc.
No issues what-so-ever.

They seem ok

May 15, 2021

I must have purchased 10 of these and 8 have been powerful and fast, but 1 has stopped working unless the shaft has pressure applied, one is slow at first but returns to normal after it is cycled a few times.
All the servos have only had moderate use.
I find this failure rate worrying ;(
Problem now is what do I buy instead next time?

Great servo, but the supplied hardware is naff

Have these on throttle in large IC boats, the servo itself I cannot fault, but the supplied plastic arms are rubbish, they're very cheaply made from nasty plastic.

Great servos for a great price

I have so fare "abused" these servos trough about 60 flights/7h of 3d flights with gyro in a 52" EF slick and they are still going strong. would definitly buy these again for a similar project.
I opened them and added some grease to the gear prior to use.

I use this in the weapon of a fighting robot. It is exceptionally robust and reliable. I bought 4 and none have broken yet!

It works perfect with 8.4 V
Tested in Jet model so in big piston (DLE120) on throttle just at the engine.

I bought a mixed bunch of 390, 393 and 396 servos, initially they were great apart from one failure on arrival. Within a month two more had failed and were replaced. 3 months on and I have 4 more total failures and 2 that are glitching.
Don't buy them!!!
