Norton UAV Engine

[jetav8er]

I have a Norton single rotor air cooled engine that is used on target drone aircraft. It has an oil pump to lube the rotor. I was wondering if you still have to mix oil with the fuel. I am using it on a go kart. Any help would be appreciated.Thanks.

Yes, a 50:1 mix of synthetic two stroke mix is about right.BUT, the engine relies on forward motion of the plane, about 200mph+, to force air through the centre of the engine, distributing the pumped oil to main and rotor bearings and removing heat transferred through the rotor walls from combustion. They don't last very long if started and then not launched within 30 seconds.Later versions have a belt driven centrifugal fan to suck cooling air through the rotor and can be ground-run for extended periods. I hope you have one of those.

I don't have one with the fan but maybe I can rig up something. I'm hoping that running it on alcohol will help it. Thanks for your help.

Sounds to me like "Stand well back" would be good advice. Keep the flag flying.

I like to use the phrase "Light fuse and get away".
