spin props in or out?And why?Mine are out and carries the bow a lot. Thinking they may be better in.

Spinning in gives more bow lift than spinning out

Out. I tried several sets of props from Cobra but had porpoise problems on top end. They finally suggested I turn them out and it should help with the top end porpoise. With that said, it would totally depend on your setup. I'm running #6 prop shafts on full SCX drives. Totally different from a standard bravo setup. It did help with the porpoise though!

Buddies 37 seems to hop a lot. Might be a characteristic of the hull. His is a staggered #6 boat.
