hmmmmm...........failure

When I take it above 1/3 throttle, the prop begins to suck air and cavitate.......then it looses even more speed.
Its only sails margenly faster than stock

My prop is at the same height as the ones that where on it before the mod. The boat also sits the same depth and atitude as before.


I have tried it with 8 x 2400 , 8 x 1050, and 3 lipo cells
They all perform almos identicly.

There is alot of drag in the baot that has to be overcome before it can get up to speed.

I am going to seal the hull ALL the way around. There is actualy quite alot of water in the hull, outside the weater tight compartment........this is just dead weight beig hauled around.


Pompebled, you are right about the cooling. Only a few drops came out of the "exhaust"
