I wonder if anybody can point me in the direction of replacement motors for the Graupner Speed 500 ECO which I have installed in a Graupner Wiesel Torpedo Boat?

There are three motors and all have failed and these Graupner motors seem to be unobtainable.

Cheers

May I ask a simple question How on earth did you burn out 3 motors

Ha Ha

They were not burnt out, lack of care and rusty as hell

What voltage are you running the motors on? What size props do you have fitted i.e. Diameter x No of blades.

I have also used two JR 480 motors in my 1:50 H.M.A.S. Ararat which is about the same size which give it more than scale performance.
