"Fantastic" On my "short list" of builds!! I already downloaded plans and build articles from "outerzone" and scaled it down to a 48" Wingspan, and printed the plans!! (I'll do electric power).

Finishing up a Great Planes "Slow Poke" and hope to start the CD early summer! Are you doing a build log?? would love to follow along!

You do indeed see the magnetic system. It is far and away a much better way to build than any previous way. it does cost a few bucks, but it was worth it. You can do a lot of different tasks and setups with the system, all the while avoiding pin holes and split wood.

No build log, just the photos I've posted. I'll finish up the color trim and glue on the canopy tomorrow, and post the final photos.

I'm just starting on the 60 size Cloud Dancer. I'm shooting for 6 lbs and about 900 watts of electric power.

I've built hundreds of models (either from a kit or off of plans) and scaling up the plans by hand off the computer monitor, I am coming to realize how HARD it is to build a Clark-Y with a tapered chord and thickness! Decades ago, I learned how to do symmetrical wings with taper but never have done a tapered Clark-Y and it's a trick! The difficulty is where to put the leading edge notch on each rib as it progresses from root to tip.

If the notch height rises (relative to the MAC) as the wing develops from the root to the tip, wash-in is developed even tho the aft section of the rib is flat bottomed.

Fred Reese (designer of the Cloud Dancer series) either fell into the right concept by accident, or did a lot of work to get the progressive airfoil "just right".

I've only flown a couple Cloud Dancers over the years and I cannot recall doing true spins with either (and I really want this model to do flat spins!). Wash-in is conducive to flat spins but also to deathly tip-stall rolls on slow approaches!
---------------

I fly at a lot of fun-fly meets; especially Big-Birds. I rarely build anything nowadays that is under 80" span. The 120 size is larger than I want to build (weight wise at 86").
There really needs to be a 90 size Cloud Dancer at 80-1/4"!

And where's the Cloud Dancer Bipe?
And... The Cloud Dancer wing shape lends itself to a Fokker D-VIII merely by adding 4 or 6 root ribs in the constant chord mid-section.

Wouldn't it be easier to have the 120 sized plans reduced to the desired size, say 50%

If you have the 40 size plans, they could be blown up to the 60 size.

Either method should reduce your airfoil design problems.

It looks like it, and I would really, *really* like one myself, but unfortunately that's not something I can spend the money on now. I've been sort of, kind of making a bit of a copy as far as a few props here and there, making me feel intensely guilty for using someone else's extremely wonderful idea and not buying his quality product when he's already so generous with his knowledge and has that great site, and how about some of those builds he does? ("He" being the webmaster at airfieldmodels.com). I recommend that site to all air modellers and that jig system too, he would genuinely appreciate the business, look after you and you can be confident of a real quality product. Yes, it's a plug but it's from the heart because I think it's warranted - and I haven't even bought anything there (yet)
