How ‘bout just a turbocharger on my lawnmower? Get that blade about 22,000 RPM and I’m mowing tree tops, baby! Lawnboy my a$$!
If you have the blade on right, @ 22,000 RPM, you would need to turn it upside down to fly it. I expect a short flight if you are going to mow through the trees from the bottom up. I'd also invest in 5-point harness and a helmet. Let me know when and where you want to try it. I'll bring the beer and record the historic event. LOL!
blade tip speed would be super-sonic, it would destroy itself in no time at all going that fast.
