Comments: Very affordable, water proof, metal gear and high torque. Very happy with servo had no problems with it in my crawler.

Comments: I've purchased a bunch of these from eBay and they are super servos! Much stronger than anything else in their price range, very quiet and VERY strong! I use four of them in my custom 4ws Summit, and they fit the chassis perfectly. I also use one to tilt my camera on my FPV build. I put a FIVE POUND dumbell on the tilt and it was able to tilt it easily AND maintain it without drooping, then return to center! It's INCREDIBLE and certainly worth the cash, beats out other servos 5-8x its price handsdown! :)

Comments: not the best centering under load or the fastest but if it had any more power it would snap the c knuckles . i used this to replace a tired hitec 645mg , i would say this has more power but the hitec was 7kg and this is 16kg but i dont see a huge improvement so i think 16kg is a bit over exaggerated unless its limited by the bec of my speed passion esc
overall nothing else is this powerful for the cost
