good servos for that money, for 450 t-rex ccpmOrdered 3 for my Trex 250. They fit in perfect and are great. Only thing is the elevator servo started this weird bounce back now after 2 flights. I can't do anything to stop it but replace it.I was bought three for my HK450. It has very accurate and fast operating. It is really nice even cheap price. Very nice servos.4 achet = 1 HS, 2 impossible de mettre au neutre. 4 bought = 1 HOURS, 2 impossible to put in the neutralKlasse Teil Fliege es in einen CopterX 450 = T-Rex 450.
einziges Merkel die Hrner solte man mit Aluminium Versterken.Ok servo. Used on flybarless cyclic. Cyclic stability issues indicate it is not as fast as advertised. Casing material is brittle and will disintergrate easily. Gears developed slop within 10 flights when used on the cyclic of a flybarless 450 used for sport flying.
Be ok on a training heli for cyclic but then again so are the HXT900 9g's and their 1/4 the price.This was initially what seemed like a great servo as it's pretty quick and strong, however, it developed an insane amount of gear slop, so much so that it's constantly wiggling back and forth trying to center. i don't know if its because lack of grease or something but it's barely usable in my tricopter...
If you do decide to buy this, open it up first and grease it like hell.-2 * for play in gears. So far, these have biggest play of all servos I used.I use 6 of them and never got trouble. Very good and preceise Servos with smooth noise. In my opinion the working range of plus minus 400 micro seconds lead only to a deflection of only plus minus 100pcnt of 1500 micro seconds mid signal (Spektrum and JR). For helicopters enough but for use as universal servo ist that a little bit too low.Great servo I'm using it on the Cyclic of my 450 Pro and they are very precise and hold very well. The resolution is great! Corona gears fit this servo also. These are Just as good are better than Hitec 65MG's because these are digital and cost less than $10.00! The speed @ 6v is just about as listed... most people don't think to rate the speed only at 60 degrees and not the full arc of the servo arm.
