By the symptoms displayed, it appears as if the electronics have gone crazy. That stinks. Probably less than 10 packs ran through it. It has never seen water or mud. Looks like I will be re-installing the stocker for now. I may try the 390 servo. Anyone else have a similar experience? Any anecdotal evidence from anyone who has used both that one or the other should work any better? Trying to keep this thing running for my son is becoming a full time job. Thanks in advance for the assist.
