I would think a regular .3 would be okay but it's a pretty inefficient setup.
Interesting. It is 5000KV and I assumed 8V x 5000 = 40K RPM, which is not a lot, that's why I thought 23T would be needed for top-end.
But if 16T is enough for long straights on big tracks to keep up with the 4S crowd (bashing fun, not official racing), then I will go with 16-18T tops.
Thanks mate.
