Proboat Impulse 9 on 2S LiPo FAIL

Proboat Impulse 9 Modified to fit an E-flite 2S 20C 800mah LiPo.
Fail, boat just runs in circles & cavitates due to prop spinning too fast & air void behind V hull. May need to redrill hull to lower prop and or increase prop size. The servo was moved to make room for the LiPo.
