Super Servo habe es in einen 500 Heli
als Heckservo eingebaut
super schnell und starkGreat for the HK450 TT FBL V2. Fits perfekt.very good servo for my HK500 heli tail .No slop good centering and does not get hot at 333hzThe RS- 3868MGT replaces very well on my DS 525 Align T- Rex 450 Pro DFC . The tail is locked with my Gpro Align . Twice cheaper for the same values.
The frequency is 1520usstandard band.

I was using this servo in my hk 500 and after the fourth flight he began to jam . My luck was that I realized the problem still on the ground. I do not recommend.Decent servo. Has plenty of torque though it's not very precise. The gears are very tight. I've used it on my Align T-rex500. It was ok but I found it a bit stiff. I moved it over to my thunder tiger E325 mini titan and it was more suited for that size (450). Held quite nice on the TT. My friend is using it on his 450 pro and its good enough for basic flight but the tail doesn't hold as nice as with an Align/futaba servo. I would still recommend this.This is the perfect tail servo! It works extremely well with the Robird G31 which somehow "didnt like" my Align tail servo.
With this servo, the tail of my 450 heli holds "rock solid" during all maneuvers. The servo was totally cool after 6.5 minutes flight time. Robird settings are: 1,5 ms, 333 Hz.
There are two small drawbacks, though: Due to the "huge size" of this servo I had to shorten the tail rod by about 5 mms in order to achieve the infamous 8 tail pitch at servo neutral. Also, my heli got tail-heavy and I had to compensate this with another 9 g of weight in the helis nose since, as we all know ;-), FBL systems do not like mechanically imbalanced helicopters.
Apart from this, this servo is just great.this Servo is great!!nice package and the quality is perfect..................
i use it on my hk450profbl
i can say it works perfect with my hc3x:-)
it is very fast and strong for all kind of flightstyle!
