My cousin is getting the UL-1 and I would like to be as fast as him if not faster. So I am thinking of getting the prop adapter to run a Grimracer 40X57 3 blade with the UL-1 motor. How fast do you guys think that would go?
Thanks, Chris

no testing today. Im off work tomorrow so if its not raining I will test it then. The only thing is my 4s I have is damaged, I accidently sliced one of the cells with a razor blade. It was fully charged and it only sparked and nothing else. The only problem now is that when I charge it, three cells balance to 4.20v and the fourth one balances to 3.83v when its fully charged. I used it in my Truggy and it works fine but now the runtime is a lot shorter. Should I be using this in my boat?
