Using as a rudder servo on my 50cc Slick 540. A ton of power, great centering and plenty fast. I will purchase again on my next big project

I also put one in a Losi 8ight, buggy. Seems to have lots of power, the build quality appears good and the price can't be beat.

Bought two of these to replace the steering servos on my Traxxas Summit 1/10. They are very strong and the centering in great. Highly recommend them for all Traxxas 1/10 models. I now also them in a 4x4 Slash, a 2WD Slash and a pair in a Nitro Revo. A great alternative to the more expensive brands.

not a good purchase. the gears have a LOT of slop, which makes it very inaccurate.
another problem is that it is not a HV servo. it works on 6V at most.
it is quite strong, smooth and fast though...
I have this servo in my savage. better than a stock one but its sloppiness is annoying

In my country the presentation of an asset, and selling another, is called the least, misleading advertising.
For the amount of people already mentioned that the voltage is other than 7.2.
Those responsible should have changed the data about the product!
And now?
I'll stick with something different than what I bought?
Or go back and hope it gets to be refunded the money that will be in credit alas?
And caught in more money and go buy another servant to the other side!
Well I hope you do not need anything else from this site.
stay well
