Pitcheron wing camber control


Thoroughly bored, as only someone with a day off, light wind but driving rain, a Shredder to finish but no materials, and a pub nearby but a girlfriend who wants a meal out tonight, can be.
So I returned to my doodles of a skinny little 60" pitcheron I'm working out. A small cog ticks in my brain and I wonder if anyone has thought of a second set of cams at the back of the wing with bigger throws (But presumably needing less power) to drive rear flapped portions of the wing.
You could adjust camber/reflex, add snap flap, maybe even differential. And of course, play with the foil for braking effects.
Sorry about the doodle. I know the cams need drive slots, after all I've just spent ages tweaking my Shredder cams.

I reckon you'd be better off flipping the back one around the other way - it would take some creative mixing, but I don't see why it couldn't be done.

Good point it would keep the rear cam a bit shorter.
As to the mixer on my Cockpit SX I'd use aileron to flap mix and elevator to keep the foil inline, and flap for camber and reflex. Whether it would be worth doing it a different matter altogether.
I think I'd need to be VERY bored.

I can't see how you could do this effectively with cams in the fuse. I'd love to see it done though. Usually space is at a premium in a twisty fuse, especially a 60 incher, so wouldn't it be simpler doing it this way? https://www.rcgroups.com/forums/show....php?t=1438425
Better control, more throw for flaps, ability to switch it on and off for different flight conditions.

Very nice I missed that. I also like the Hypnosis2 with the airbrake style flaps.
