Any one with a Redcat EPX having problems with throttle response glitching? When pushing the throttle quick, the tsunami just jerks. If you push throttle really slow then it will move, but you have to do it slowly. Batteries are fully charged, Brand new ones is radio and Tsunami is brand new. Tried a second radio and still the same. Just wanted to see if anyone is running into the same problem or if i just got a bad one to start with. I am guessing the speed controller is shot!
