Im having a few problems with my buggy. The first one, Before running my spektrum radio the buggie would drive alone(keep going when i left of the trigger) or do a quick burst of speed while running but just once in a while and not all the time. So i started to use stronger AAs for the revceiver and it helped with the driving alone but the quick burst is still there. The quick burst doesnt happen that often anymore while driving. Mostly after taking a jump the wrong way and it crashes. Then the thing goes crazy til it hits a wall! This only happens when the car does a bad flip of a dirt jump on the track. The second thing, when my glow stick gets close to my servos they start to twitch. The last thing, im still learning to control my nitro so im still crashing after jumps alot. The thing is im running off the track every minute due to my pipe coming off. Is there any trick to keeping it on so i can stay on the track longer to practice?

is it still glitching with the spectrum radio?

I had a AM radio first. At that time i got glitching alot when the glow stick came near the receiver when i start to place it on the glow plug. Doesnt glitch while driving. The only problem while driving is that the aceleracion seems to pick up by its self at times. Im running a spektrum radio now and the problems dont happen as much but the car still seems to drive it self at times.

try puting a rubber piece of pipe around your exhaust pipe to stop it from coming off or you could use a shell that screws closed like the ones plumbers use to keep rubber pipes on hoses for washing machines.
