Removed metor .60 as it over heats. ( 15 years ago ). Got an Irvine 120 marine and X75mm prop, but never installed. I am now thinking of converting to brushless using 6s lipos ( I use these in model helicopters ). Any comments on either setup would be appreciated. (Motor: Metor .60 aero with a copper coil around head for cooling) (7/10)
