Just a quick question? Has anyone new start running in your class. What radio and rx are you running. Last year I started running a new track during practice my truck seemed to run fine but as soon as the race started I would just loose throttle but still have steering swore it had to be my mmp. It ended up being someone in my class was running a low end radio and rx and it would make my spektrum radio freak out. Ended up buying a mt-4 that same day and all my troubles went away and didn't have to run the e-bec anymore.
