I have the jr 368 in my h9 edge 540 on the elevators. mounted in the fuselage. they work great and very light. as far as fun flys. go with tower hobbies. I just got some ts-35mg mini servos 4.8 volt is 14sec. 55oz of torgue 6volt .11 sec and 67 oz. 32.99 and there new ts-59 low profile aleron servo is 27.99 4.8 is .18 sec and 61oz at 6.0 volts .14 sec and 76oz. these are the same as hitec servos. I use tower servos in alot of my cheaper planes and never had a promblem yet. but I did have to send in 10 hitec 5645 digital servos because there end points were messed up.
