Default RE: Finally almost ready 12.5" bbyracing micro jet boat

Yep it's confirmed, 11.1v on 3200rpm/v it's quick but overpowers the hull big time. Could only get 2/3s throttle before she starts jumping and porpoising everywhere and that is with all the weight moved to the front. So much so that the jet actually comes out of the water with the nose almost completely in the water, so I would have to push the back down just to get the water pumping through it, then let it go. Ordered some lipos 7.4 at 2000mah, it's 20 grams heavier per Lipo so it will add 40 grams total to the weight of the boat when running 2 in parallel. With any luck this will be enough weight as it seems to be just too light, you would think being lighter would be better.

Also ordered a new esc for the inrunner, apparently they have 30 and 50 amp Esc's that run both forward and reverse! The reverse on the jet will be nothing to write home about but it can actually move in reverse providing the jet is fully in the water.

Well after talking to Quicksilver, I've decided to flaten the hull, the front of the deep vee might be the issue... will find out later this week. Going to leave the drive as is for now.

Here are some more pics.
