Yes that's really fast!..pushing the speed limits,and that's on 4s....so if I want to run 6s I guess the Leopard 3674 2200kv or Turnigy xk3674...I've been looking at different motors and wanting one best to run 6s and be capable of 60mph,but mostly would be running in the 40's because most of the time the water is a little choppy,I'm running the stock 42-55 prop,going to try the 45-68 prop tomorrow. The other day though my motor was smoking a little,and I only did a few couple second full speed during the run...esc though wasn't hot at all..?..I ordered some Trinity brushless motor oil,..manual says to spray a "water displacer" in water cooling jacket and motor often,need to get some: )
