Gentlemen,

Thanks for the information. I realize that I was a little vague on the description of “good” turning performance.

My ultimate goal is to put together a program that will calculate the radius of the turn, velocity at the exit of the turn, and other information. I plan to use this to optimize my current RC Combat design and mainly use this model to get a better understanding of the physics involved.

My approach for airfoil selection has been to try and factor in 4 design parameters. I tried to find the best compromise between Cl, Cd, Cm, and percent thickness for strength. I sorted through airfoils with SNACK and chose the Selig 8036. I’ve also examined wind tunnel data from Selig’s site and the 8036 performs well for Re above 300,000. There’s a new combat class in the works with lower Re’s and limited thrust. So this go around I’d like to use turn dynamics to help with design.

AQ500, I’m a ME as well. I’ll look for the Anderson text. I used the Perkins and Hage aerodynamics book in school, but donated it to the university for use in a design competition project I started. Should have kept it around I suppose, that darn 20/20 hindsight thing…
