Not only was it like pulling teeth with motion to replace the servo from the brand new mig29 right out of the box but the servo started twitching uncontrollably and only way to stop it was to move it up an down and sometimes it would stop and somtimes it would not an i sent them a video of how notchy they where in comparison to the rest of the servos on the jet which were fine. But they kept saying there supposed to be notchy like that and that the twitching of the elevator up an down very fast was normal because it didn’t have a (load) on it they say because it was a (high torque servo) not only is that complete bs. Because i have plenty of big warbirds and 3d planes that actualy use real high torque servos and none of them ever done that. Nor out of the 200 somthing planes I’ve owned. Over the last 18 years ever done that. So they where just horrible to deal with. Horrible customer service especially when it’s my first time dealing with this company and buying there most expensive edf at the time. And that’s how they act. They since sent me another replacement but it was still the same. So for anyone buying this jet. There is a set of hitec servos that are perfect for this jet. HIGHLY RECOMMEND taking (there upgraded) elevator servos out and tossing them right in the trash. And get the hitec ones. As I’ve done. I forget the exact model number but there on the forums if anyone is having a simmilar issue. Do not fly with them servos. I’m not the only one that has had this issue tons of people have. And some actually got a decent set that works for them. So it’s a bit of a gamble but with a jet that cost as much as this one’s does. It is not worth the risk. Change them out. And you will have a reliable amazing jet. Besides that issue i absolutely love the jet. And flys amazing now and i have the piece of mind of knowing i wont have a stuck elevator servo in flight that could be catastrophic if you do not have enough altitude to correct if this issue were to happen on takeoff or on your approach it would be the end of the model highly recommend replacing with the hitec mini servos
