I can see where that tool is good for determining motor size. I often use The off the cuff SWAG (Scientific Wild A$$ Guess) method is the 100watts
ound rule. 100watts per pound for scale mild flight, I think it was add 50 or watts for aerobatics, and anything more than that move towards 3D. Again, that is SWAG and not bullet proof. Wing loading was not something I had ever been able to figure for until now. Thanks for upping my SWAG abilities.
