Okay, plan B. After much thought and technical discussion with the brainiacs on the board, I am going to stick with the HvMaxx. It makes sense really since I dont need gut wrenching torque, and I dont use the truck that much either so putting an expensive BL system in there is daft. What I am doing is upgrading the motor with the sintered rotor which should be here next week with any luck, and also finally replacing all the tamiya connectors with 5.5mm gold plugs; no deans please, my fingers are too stubby. At the moment the weather is being crappy, so testing will occur when I have a window in the weather & work. Thankfully however I get 4 weeks off at the start of august (college students on summer leave = no customers), so I will have plenty of time to bash/test/repair/tweak etc.
