Jim how will you mark improvement ,in the engine, with this test stand? Will you manually record data and analyze it, or are you just looking for more rpm? Seems you could still record 2 parameters of x and y and render visual plots using a graphing calc or excel.
I wonder if my electrics will need a ducted fan unit versus the plane props if I am to test in upwards of 40K?

BTW: The john boat is registered and ready to go. Looking for a small trailer to pull it. Running a digital motor guide troller,works great. I will be ready for falls lake! LMK .Im still building!

JA:

Please tell us about the safety cage you will be installing over
the propeller - for that matter - make one to fit over the whole
*amn thing!

We don't want to read any headlines like:

"Lexington Man Impaled By Flying Debris From Toy Boat Motor Testing
Machine........
Condition: Stable and improving - Expected to leave hospital soon."

Sure, we will send you candy and flowers but we would rather not
need to.

Thanks for explaining your safety procedures. I suspected you were way
ahead of me on those details.

Considering you are probably going where no model engine builder has
ever gone before, I think your last post makes a very fitting addition
to your thread which BTW is absolutely astounding.

I sincerely hope you exceed your wildest expectations.

I'll make you a deal. You can do the learning, I can do the work and we'll both make some money.
