Well, Ace. Big of you to apologize somewhere in the middle of this thread. I thought you were taking some unnecessarily hard knocks, and still managed to keep it together, Good on ya kid!
You probably do have legitimate reasons for keeping the info to yourself, especially if someone is basing sales on the secret. Fact is most of us won't buy one of the $100 spads your club sells, and we will get by w/o knowing the secret to the elliptical Spitfire wing, but heck it still would be nice to know!!?? Besides if word gets out on the elliptical wing, it won't be long before someone finds an even better way to ellipt it!
And that will help us all.
Below is my buddies Spit with an elliptical tip and a two fold L.E. Looks incredibly real in the air!
