Used to be fitted to the Chinese imported fast gentleman's run arounds.
Fast torky motor and I suspect a suitable alternative would be JP Pro Power 480 Electric Flight Motor

Match it with one of Simons (ex Prop shop) racing props and you won't be disappointed.

Thanks Jarvo. Already had a look but they have deleted all brushed motors as far as I can see. Maybe I should follow suit but still hanging onto the past.

Looks like a standard 600 motor with a nice colour, try looking on the overlander site, might still be offered
