It needs to be a fast airfoil. I'm probably wanting to much (ya know my cake and eat it to) We had our first combat event a month ago and after watching my foamies that I build go up against 11 other guys I realized that I NEED to redesign my planes. I love the way my foamies fly for all around fun type flying but for combat they leave ALOT to be desired. I've been building these with the very scientific "that looks about right" method. They are to slow. Don't turn tight enough, and several other things. I just need to start by choosing a good airfoil then design a plane around it. I could just buy one but I like the building/designing part.
Let's go back to the simple fully symetrical foil. If I go with this, what effects does spar placement have? If the thickest part (spar) is close to the leading edge it will produce alot of drag,,,(right?)
How far can I move it back and what will that do? What will a tapered (thickness wise) do 1 1/2" at root/ 1" at tip. Is this a faster design due to thinner profile?
