Rick Posted August 31, 2007 Share Posted August 31, 2007 Have got a Hyper ST Pro Trying to fit hitec HS 625MG servo for the throttle but when fitting the arm Ho-Bao supplied it goes to deep over splines and fowls the body so jams. Also the using a Hitec HS 645 MG for the steering and the arm supplied by Ho-Bao (metal) will not fit on the splines. Are these servos no good for the Hyper ST kit or should I use the arms supplied with the servos, the arms have a lot smaller holes so would have to be made bigger thus making them weeker What should I do ?

tjpMT2 Posted August 31, 2007 Share Posted August 31, 2007 the arms are designed for Futaba servos not Hitec servos You need some Hitec Servo Horns Quote Link to comment Share on other sites More sharing options...

Rick Posted September 1, 2007 Author Share Posted September 1, 2007 the servos do come with a assortment of horns that look like they will do the job but it would have been nice to use the ally ones that came with the kit, obviously not going to happen thanks for the advice.
