I hope that I can get some questions answered, I am changing over my RC8 with the Tekno V3 and a MMM Esc, what I need to know is, I want to run the car with a 5s Li-Po for club races and then if I go to a ROAR Race where the rules are 4s only, what Neu Motor will work for both Li-Pos. Also who else makes the 6.5mm bullet connectors besides CC. Thanks if you can help.---Jerry
