As you say, it is important to get both wings equal and then fine pitch trim adjustments can be made by the adjustable elevons.

It might not need a whole 10 degrees if it was made with an airfoil which had near zero or positive pitching moment.
Suggest something in between the airfoil used here:

and a normal, thin, flat bottom airfoil.

You might check out the airfoils in Barnaby Wainfan's Swallow. These are for a slightly swept flying wing with taper.

yet another Great Lakes Trainer

This one's a 12 inch dime scale from David F. Duncan Co. Or at least I think it's dime scale, I don't see a year on it. Designer is L.H. Deubler. This appeared in the Jan/Feb 1995 Flying Aces News.

I have a similar Practical Scale plan (a BE2e) and the sketches and legends (character font) look similar.
Anyway, here's the link. Have a look and see what you think...

Hi Brian,

Thank you for the interest in my problem. The model plan in question is a 33% S2-A 80 inch span.

The Clark is an S1-S at 33% with a 68.5 inch span. It is more obscure than some but I have the Clark as well. It is a fairly sophisticated plan. I actually have Toni Clarks custom ZG62 with damped mount and custom intake with SS exhaust cannister to accompany the plan.

Thanks again. You have the only attempt thus far. I amazed that no one knows.

Thanks again, Bill

Black Chiffon and PZL P24 Fighter

From the Aeromodeller of October 1952 I introduce the Black Chiffon and the PZL P24 fighter.

Black Chiffon is a Class A (2.5cc) team racer designed by C. Milford. It was designed after team racing had been on the books for a year or two and people were getting a feel for the type of planes that were winning races and inverted engines seemed to be the way to go. I'm not sure if the plane actually placed in any races but it had been developed over five models. Interesting finish details!!!

The next one up is the PZL P24 Fighter designed by D. Bryant. I am not sure if this is the Dennis Bryant or not but the plane is certainly worthy of him. The model is 36" span, 1.5cc powered, scale model of the Polish Fighter plane. It has knock of flying surfaces and pendulum controlled elevator. An interesting build and certainly one for consideration if you want a small, realistic, radio job.

As always my drawings are but tracings of blown up scans and may well contain errors, please measure twice before committing to any knife work. If you notice any mistakes let me know so I may rectify them. I will be forwarding .dwg files to Steve at Outerzone so he may host them.

Most of all enjoy,

Al

Dennyplane

Does anyone have the full-size plan for the 30's "Dennyplane" from Denny Industries which they would be willing to post?
The "Dennyplane Jr" 48" span is already here, but I am looking for the original, full-size 72" span model.

Any help would be much appreciated.

Thanks

It looks like the AMA has it if you can figure out which is the right one. The listings seem a bit confused!
http://www.modelaircraft.org/files/D.pdf

These guys below, and some of the AMA listings, indicate that the Jr. is 72 inches:

I've ordered from them before with good results, some years ago.

These guys seem to have it, and they're inexpensive:

Bob Holman may or may not have it, but he's got a picture of it:

Anyway, those are some of the usual suspects, but there are many more.

Some cleaned and joined plans

Here are

Cleaned re-scan of the interesting canard pusher Velivole from Aeromodeller June 1946 (originally uploaded by Aeromeddeler in post #2373), together with the article and the Aeromodeller front cover (from Colin Usher's site)

Cleaned and joined versions of Walt Mooney’s Piper Pawnee from Model Airplane News December 1965 (uploaded by Frankyfly at http://www.rcgroups.com/forums/showt...3#post16709735), and his Piper Super Cruiser from MAN April 1967 (scans from http://waynesfreeflightmodels.wordpr.../mooney-plans/).

Here are some plans scanned from the June/July 1996 Airflow newsletter. This issue was edited by Dave Stott, sitting in for Vance Gilbert.

I've included zip files, but I'm not sure they're necessary.

The Flying Aces Airhopper appeared in the Jan 1943 issue of Flying Aces. It's 15 inches span as printed in Airflow.

The Humdinger appeared in the November, 1934 issue of "Sportsman Aviation". Sorry about the low quality, the drawing in Airflow is pretty bad too.

The last model is Comet Kit A6, the Stinson Voyager. As printed in Airflow, it's just over 12 inches span. Not sure what year this one came out. Suggest using a better prop than the all flat one shown.
