I'll have to disagree with that TimBle, actually he stated just exactly how cheaply, and poorly the servo is made, the reason's why the servo is junk, and so forth. He didn't pull any punches, told the truth, and plainly, and honestly explained,and showed why the servo was junk. opjose states ( He needs to get a bit real... he's talking about a 1" length or less... SHEEZ!) apparently his chinese engine/engines don't/doesn't have any vibration at all. You can put an R, and X, or even a Z behind the 995, and it's not going to change this servo.
