RE: the OFFICIAL R-40 thread !
hey mtl racer, the reason why the servo cost so much is because it is a possiblity that it is a digital servo. they are a lot better compared to the analog servos that you find under $50. digital servos are a lot faster like .06 secs with 120+oz/in. where an analog servo is about .15secs at the same amount of torque. but the only issue with digital servos is that it gets annoying as hell trying to center them because it sounds like a little bee buzzing around constantly. i am also running at JR system in my R40 using z550 for throttle and z650m as my steering. hey i was curious what upgrades have you guys done with your R40s and have you guys had any issues with the side belts falling off?
