I just had to swap out a servo in my 2.5. Burnt out the reverse servo due to water So I got the same water proof steering servo that is in my summit. Put that in place of the steering servo. Swaped the steering to the throttle and throttle to the reverse. Sealed up the old ones to make them a little more waterproof. Now when I first start it the throttle has the jitters and likes to go full throttle unless I keep the breaks applied. Once the engine warms up everything is fine? I can let it sit their and idle forever and it won't rev up. Never did this before even with cooked servo.
