NOW YOOOOU finally got to the point, I've used a fan and the controller needs a bec or receiver pack to work and I put a pack and believe me the thing is silky smooth, but it starts to thermal once you use sudden acceleration more than 3-4 times, after that I started to think that the 1920/8 is too big for the 55-10-32 to handle, but maybe the twist-42 will work much better and yes as you said its smaller and it surely drains less amperage than the 1920. The gearing hasn't changed since then though.
