coroplast control line planes

Has anyone built larger controlline planes out of coro plast or know of anyone that has plans. I have built small planes from coroplast. I looking for something 40" or larger .35 or 40 size engine.
THANKS

If someone can build semi-scale aircraft with 50 to 60 inch wingspans using cardboard you should be able to do the same with coroplast. There have been a couple construction articles in Flying Models and one in Model Aviation. The process is described in the September 04 Model aviation control line scale column (page 139).

The keyword is "SPAD". Here's a long, long thread about the subject, and there's a picture of a Control Line SPAD somewhere in there:

(Yeah, yeah, it's RC, but so what..)

You need to spend some time at www.spadtothebone.com and look at the stuff there and search for CL planes. It has been done a bit, and needs to be done a bit more. I have barely built in the last couple years otherwise I'd have done some things. I do have several of the Manwin trainers and have fun with them, but I want to build a similar Bi-Slob equivalent and need to work on that.

In any case, there is the Circle Jerk and I forget what Tattoo called it, but he made a CL plane and flew it too. Scarey? He used a spare 46 engine and some fiberous cable stuff that he scrounged for control line. I guess the tensional strength of the stuff he used was really good, as his plane didn't fly away, but if I'd have been there, I think I would have let him borrow cables.

Although I wrote the article, and gave Brodak the BiSlob details, with Ron Pavloer's permission (Ron designed the Slob), you might recall that I mentioned in the Flying Models article, that Ron used cardboard for the fuselage of most, if not all his BiSlobs!

Hey, that's my cardboard model you're talking about. Hi, this is Chuck Felton, builder of the cardboard model Yak-9 featured in Bill Boss's latest column. The attached photo shows the good scale appearance that you can get with cardboard. Go to my website at
http://home.earthlink.net/~charlesfelton to see photos of other published cardboard airplanes, both R/C & C/L, and construction techniques. Cardboard airplanes have been around a long time, longer than coroplast I think. My first published cardboard article was in 1976 in RC Modeler. Give them a look and give them a try, I think you will find them enjoyable.

What is a typical source for coroplast? I want to buy some to try and haven't a clue where it can be purchased.

Hello Bill,

I got a piece 1 ft. by 3 ft. at a sign shop for about $ 1.00. That is big enough for the Manwin Trainer mentioned by WCRANE in this thread. If it works I may try well something bigger later.

Look under the Yellow pages under vinyl supplys or signs. I used to use the material and apply cut out vinyl letters for signs. I used 4' x 8' and cut to the size needed for the job. If you can get the wholesale people to sell it to you it should be inexpensive. If not see what a sign maker will do for you.

Pay for it? Hell man, the highway is littered with it! Nobody gonna miss one little campaign sign, that should score you at least a 3x6 sheet.

Coroplast, really the only good thing about campaign season.

Two days after election day if the campaign sings are still up I declare open seasion on them. I like the 4x8 signs the best.

I did a Fox 50 size coroplast rc plane. Used a yard stick set on edge for the spar and plywood set on coroplast rails for the motor mount. What a durable plane. You can't destroy them.
