I've read enough to be dangerous and most setup threads tend to be beyond what I'm looking for so, please pardon if this is post is totally redundant.

Looking for prop and battery size suggestions for making the 4 minute heats, as well as any setup starting points.

I'm changing the flex shaft and coupler. - any other changes I should make off the bat?

Props - x442, x642, m445?

Battery size? - I'm looking to get 2, 4S packs so is 3300 enough? Will 5000 get me through two heats?

Strut setting - Flat? Seems most mentioned 1/8" above sponsons - still correct?

Again, I apologize if this has all been written. I searched and read a bunch and most seemed to jump to 6s or the 2030kv aquacraft motor.

Thanks for any input!

Charley
