Watching these fairly large RC Jet videos, it made me wonder how much 120 lbs (or 240) of thrust could do on the back of a snowmachine.
They are light weight, just a bit larger than a beer can.
Not expecting it to be the primary power source, just a boost. Would it make a difference?
I'm just curious, have no plans on doing something like that, but it would seem that someone would be crazy (and rich) enough to try it. 67 Lb thrust engine cost about $3k US.
