i have 2 boats both with similar motors in them
one is a 19" deep vee-scaled from the gas mono plans- made from 1/16 ply- so quite light
the other was a depron rigger approx 16oz weight
the motors are decieving though -the size they staed was can size NOT stator size
measuring the stator gives me only a 20mm x 15mm
my limited knowledge -now!- thinks that is quite small even for the boats i have them in??
any help on prop sizes for motors that size would be handy!

cheers for the help so far!

speed 3-
mm. i do have a BIG 7.2 nicd brick pack i could try! if it doesnt sink the boat from the weight!!lol
