I think that by installing a slightly shorter blade on an engine, and installing the propeller on an engine, you will know if it works.
The consumer just asks two things, that it works at all engine speeds, and that the price is affordable.
However, remember that it will be installed on an airplane, and that on an airplane, everything must be oriented towards safety.
Sometimes, when I look down, I think about my safety!
I usually install on my plane, only things that works for years. You've found it, I'm suspicious.
Thank you for making available your videos.
Could we know more about your system?
