Free Amps = 1.1
Stall amps = 57
I am still working on the others,

Wow! GREAT catch, Paul!
...And THANK YOU for sharing that! (Talk about Gracious Professionalism!)
That note may have just saved the bacon on a LOT of teams! That's a 25% lower free speed than the old FP/Johnson. I can envision a BUNCH of teams scratching their heads in weeks 3-6 wondering "what the heck did I do wrong with my calculations ??", when it didn't "rev up to spec".
Major props for Paul...
NOW I'm VERY curious about the OTHER "big boy" motors!

When you find/determine the other motors' specs, can you please post the links to their data sheets too?
Thanks again!
