Hey thanks!

I have built tons of electric airplanes. This is one of the first times I was not sure about. The paper [link=http://www.maxxprod.com/pdf/HC2816-xxxx.pdf](Here is a link to the paper)[/link] they give you with the motor has a graph you have to decipher. At 11 volts and a 10'' or 11'' prop is off the entire graph showing that it will pull A LOT of amps. I called up MPI, and the technician quoted "Do not use the Slo-Fly prop because they will draw too many amps. You will need to use APC E series propellers in the 9x5 area."

O well, Electric is just a trial and error process...

Thanks again for the information.
