So I have a kraton with a castle mamba monster 2200kv 1515 motor , was working ok but was getting low voltage cutoff when a couple of times because some dirty pos at the hobby shop sold me 14 gauge adapter to run to batteries that I didn't need. I figured it out and ditched the adapter and put a 10 gauge lead from positive to positive making a series connection for two batteries. Ran for less than 2 minutes and cut out. All the previous times it would restart but this time it wouldn't so I took the mamba monster speed control from my E-Revo and put it in the Kraton. It turned right on but no throttle just steering worked. So I unplugged batteries and was reading to figure out wtf was happening. Plugged batteries back in and turn on, nothing, zip,zero,nada. What's going on. Help. I'm ready to throw them both out the window!
