Its the question which has been plaguing my tiny mind for a while now..

Assuming voltage was the same with each setup, and the motors in question were the same size (just different kvs), then I would personally favour the lower kv option, but then again it depends on what you're specific goal was.

If it was to have a sensible speed with good temps and runtime, I would wager the lower kv motor drawing less current would give better results, but only on the proviso that it could pull that taller gearing needed without warming things up too much- feigaos need not apply as tall gearing or a heavy load does them no good beyond a certain point.

If we were talking Medusa 1600 vs 2000 or something like that, then either route would be good- you'd need an eagletree to see which was the best though (and a stop watch).

I think Im taking the wimps route and gping for the 1800kv castle 1518 when its released- best of both worlds I suppose on my chosen 5s voltage...

For speed runs though (as a final thought), I'd say higher kv with with higher voltage and play with the gearing- cross fingers and pray esc and lipos dont go pop.... :/
