Possible power plant for a old Ural?

We need to get ahold of one of these Iranian drone motors and try it out in a old 650 Ural. 8)

I'm thinking they may start showing up on Sportsman's Guide soon as "surplus". LOL

I don't know, man, the power and torque curves look pretty lousy for a road-going vehicle.

Interesting details about the engine vis-a-vis its use in the cheaper Shahed drones here:

It says they weigh just 16 kg, though, which is impressive -- perhaps even unreasonably light, but I don't know much about aircraft engines. Can't find the physical size/dimensions.

Big difference between an aircraft engine and a power plant.

I had a pilots license so got into the nitty gritty. There is quite a range of max power for takeoff and what works for longevity and cruise is always quite a bit lower. You can run hard and wear em out or take it easy on them.

A drone engine is a lot different in that a cheap drone is not worth a good engine. Its going to crash or get shot down.
