RE: New Evolution 10cc gas engine
Dave,
i know they reccomend the 12 x 6 prop for all around..but to me i used the 13 x 6 blade and it seems it finds a sweet spot when its turned up..i don't have telemtry read out on rpm,but i would guess its turning 11000 to 11500 range and seems to really like it..have you tried it.. Craig
