im a little surprised that it can rev that high, most of the motors with a shortened cooling tower are usually big bore short stroke motors that can dig themselves out of a BIG hole... that would be an AMAZING motor to have, but cant afford it right now at 500 bucks.

I bet that a misprint a crank at that rpm will fall apart. the vibration alone would interfere with radio equipment. I think! 34000 RPM under a load and now I get it it has a really small piston. 16mm

One of these in a small nitro turbine jet would be cool!

All my boating club members run gas boats so this thing singing on
the pipe at 50k is unheard of to their ears. I have been sorting out
the right prop to hit 40K on the water so far 36.9k best pass. This
spring should make it happen.
