Tony,
You do make the very valid point that even my CG 330 Extreme and the latest CG 540 Edge profiles along with scores of others have no tips. Makes you wonder what the alignment proceedure for this item is when it gets glued on.

I have rebuilt this wing three times now with the last one being a combination of three wings (two from a friend) and new wood. I have all of the templates to build another wing without much worry. Funny thing is, when I did this one, I almost dropped the tips and extended it for construction and covering ease.

Do you think if a guy was to build another wing that it would matter if it was the same length but with flat ends or do you think the decrease in length was as helpful as the flat ends? Maybe I should ask instead, do the planes you have pictured and mentioned have dfferences in their wing spans of more than 2-3 inches?

It seems to me that if you have had success with this technique on several planes, there is some aero thing happening with a looks oriented detail item. I am new enough to the sport that I never saw CPLR fly this design in comp, nor could I tell you if it got "Updated" for a broad audience appeal or not.

Tony, Thanks for the info. I think you have satisfied my curiosity enough that it warrants building another wing. I'll see if a wing of the original span and flat ends has any advantage over the current wing. Probably loose the fore/aft taper on the end though. I know what this wing does. I can always cut it shorter. Sooner or later it will need replacement anyway. Might as well start now on its replacement with the same wing area.
