So i run this boat on 6s and i have the dual pickup rudder set up. (I don?t think it really runs any cooler than stock. Way to hot) I just got my dr props tornado 45 prop and i love it. First run with the new prop pulled the cover when the two graphine 6000mah batteries died and smoke came out. The top of one of the capacitors on the esc cracked and some hair like stuff came out.
