12S and 14S EXPLAINED RCTWINS is a HOW TO VIDEO on setting up your RC plane ESC to Motor to run on 12S or 14S. We have built 100 planes and they are all electric. We love ALL kinds of RC, gas, glow or electric, they are all fun. We stay with electric because its easier to maintain with so many planes. This video is one of a Series designed to help anyone considering electric rc. these videos will be focusing on topics like 12S, basic setup, ESCs, batteries and motor ESC setups that we have found to work. RCTWINS is all about helping with small medium or giant scale planes.
