for as long as i've been into nitro and rc (couple months), i sure have had a lot of problems. anyways, here it is.. i broke my throttle servo case and got a new one. i assembled it in the new case. when i plug it into the receiver while the other servo is plugged in also, they both twitch constantly. if i just plug one servo in, it is fine. and it works fine if i plug in the throttle to the steering or the steering into the throttle. so basically, both servos work fine, but together, they now twitch. any ideas?
