The fowler flaps will be a challenge me thinks. Are we up for it?

Sorry no pics tonight as i had a comittee meeting for the local cubs and scouts.

I think we can doit but now to figure out putting fowler flap into a mold wing any ideas guys

If we get Len involved I bet it would grow to 1\2 scale

I too love the looks of this plane and wish I had space\time\talents to offer to a "team" build. Alas, I will just enjoy watching this build

It might not be absolutely scale but the easiest way to acheive the Fowler flap effect is to have the hinge points some way below the under surface of the wing. This could be done as simply as two shaped bits of CFRP (probably looking a bit like big control horns) with bushes and a smooth shanked bolt for them to pivot on. Not sure how many you'd need. At least 3 (each end and one in the middle) but 5 sounds safer. The middle one could be adapted to be the one that the servo drives.

On a separate note, you'll probably end up making the flaps in separate moulds to the wing so you can get a really neat, tight fit when the flaps are closed.

For a long time, I've wanted to build a scale Sigma (http://en.wikipedia.org/wiki/Sigma_(sailplane)) and this was how I was going to have a stab at a sort of variable area. However, as I'd have to mend the boom every time it was flown (look at the fuz), it never really got that far

Watching from afar with great interest,

Glen you always make me laugh. Just when I didn't think you had any more in you, you once again step up and take it to the next level.

Boy that's come a long way in a short amount of time.

I bet you're glad you've gone foam & not MDF with a model this size.
