RCJBC K&B 3.5 cc RC Home Made Outboard

[randyneighbour]

that has to be the worst runing 3.5cc k&b ever. with the proper prop and 70% nitro it runs boats at 60mph plus

@randyneighbour You bet It could do much better, we are using methanol with 18% Castor only, no nitrous,  when I set it up with a better fuel I will post it on my channel.

@randyneighbour

Nitro fuel is to expensive down here. So we run meth and castor.

Hey at least it runs.yes it is a little slow, But it pushed a 12 pound airboat to safety!
