Mention was made of Outlaw picture one wing tip being warped or less dihedral.

It was the done thing in those days of FF models to have less dihedral on one tip, then the plane naturally flew in a circle due to slightly less lift on the higher cranked wing tip.

Never heard of anyone using less dihedral on one wingtip. However it was common to tilt the tailplane off horizontal or slight warp of one wing tip in order to induce a safe circular flight pattern.

It was a black art in those days, no instant, guaranteed to fly, models available.

Thank the Lord for modern times.

It certainly wasn't a "black art" to anyone who understood what they were doing',the purpose behind the action & took the time to trim models properly. Those who didn't had problems with poor performing models. Which is exactly the same today with a lot of RC flyers.

Pat, I think he means wash-out... or the wash-in used on the RH inner panel for the flight pattern. Either way, it's true that slight wing warps were and still are used for FF trimming but, apart from slight wash-out on both tips, they are totally unrelated to RC flying, unless you want a plane that only flies in circles and in one direction only.

Broken English

I did not mean wash out, or warping, I meant a variance in the angle of the two wing tip panels.

Tom, I flew FF competitions for 20 years, a long time ago. One of my designs won at the Nationals (for someone else!), and I've never heard of different polyhedral angles between the two wings. If anyone can quote one example of a successful FF flier doing that, I'd be extremely surprised.

To suggest that it may be a good idea on a KK Outlaw is (pardon me) ridiculous.

Apologies Tom, but I think there's a mix-up somewhere...

Well it worked for me 70 odd years ago. Perhaps you could give it a try sometime.

Cheers
