Thanks again for the info. I think I have a little better understanding now. I would have estimated the pack temp in the range you said. For now I think a will use the prop I cut down. Next time I'm in OKC I will pick up a 13x8 and give it a try. It sounds funny to me to use a 8" pitch prop to 3D but I know the elec motor is a different animal compared to a Saito.

Thanks Again, David
