Don't like it.
Came with my quanum trifecta and did not fit very well. HK recomends this servo for the trifecta but the gears from trifecta yaw mechanism do not fit properly on this servo. There was a lot of play.
I am wating for it to break and replace it with something better. But after some modifications with ducttape around the gears I was able to reduce play between the gears of servo and yaw mechanism to a minimum. And suprisingly after - 40 Lipos flown and crashing with Trifecta the servo still lives.
This servo is ****. Bought two with the Trifecta frame. Didn't even make it through one battery before the plastic gear in these "metal gear" servos stripped. Opened an RMA case with HK. Almost 3 weeks later my case is still "waiting initial evaluation." I uploaded pictures and video of the stripped gears. In the meantime, I replaced with a Corona 929MG servo. Perfect fit, works great, and seems to be quite durable based on the aggressive flying and crashing.
Avoid this servo if you're looking for an ALL metal gear servo, because this one is not. I've only been using this servo for a week now on my Trifecta, and I've somehow managed to strip the gear. At first I though I must have really done some serious damage, because this thing is called a "Metal Gear Servo", right? Well, sure enough, the first gear from the motor is PLASTIC, not metal. I guess a week's worth of flying is $5 worth of my time. Not going to order another one, though.
Here's a pic of the internals as proof: *******i.IMG width='480px'ur****/a7CaP1H.jpg
Hi there. This servo is not a metal gear server. I bought two of these and one stripped also straight away. So I opened it and guess what the main gear off the motor is plastic. Sure the rest of the gears are metal but whats the point if there is a plastic gear in there.
Then what is the point of a metal gear servo when there are plastic gears. The point to a metal gear servo is that they are stronger than the plastic gear servo's and this having a plastic gear means in truth that it's a plastic gear servo and not metal geared as they say. Can't take the load of a true metal geared servo.
