Another beaut


Foamflyer:

I've copied jpgs to my desktop of your other similar models. I enjoyed your web site as well. Am new back into RC and hve enjoyed being a lurker on the RC groups for th last several months. Would enjoy knowing any details about this design. Keep up the good work.

Wow foamdave, pictures of my planes are on your desktop? I feel honored! But really, there aren't too many more details than what I've already said. I suppose, however, that I could take some close-up pictures of the motor mount, which is an experimental design first used on this plane (and appears to work well so far). If there's enough interest I'll provide more information here, otherwise I'll get the info to you, foamdave. Thanks.

Single Aileron? craziness! Lol!
How's it fly w/ the single aileron?
Probably a dumb question, but whatever
Thanks,

AceMigKiller,
The only dumb question is the one not asked. Although single ailerons are uncommon, they work quite well and they're better (in my opinion) than traditional dual-surface ailerons. The single aileron is designed to have more area than regular ailerons, and are usually adjusted to deflect farther. It's not really noticable in the air if there are one or two. One aileron can do away with extra and/or complicated control linkages that traditional dual-surface ailerons would have, which is important on a twin-boom design. Single ailerons reduce complexity, weight, and construction time.


Marcuswhorley,
Sorry there are no plans for this plane, nor will any be drawn up. I don't use plans, as they're really a waste of time in the construction process. It's a wasteful, time-consuming step I eliminated long ago. Besides, this is a very simple design that just doesn't warrant plans. I got a "wild" idea earlier to create a series of instructional videos (on CD) on exactly how to build planes like this, detailing material selection, foam cutting, assembly, finishing, and flying. Perhaps someday I'll get around to it....

You may ask if I'm going to go to all that trouble why don't I just offer a kit? Well, because when a "labor of love" becomes true labor, it isn't fun anymore. I'm not interested in making money in an enterprise like that. However, if I go through with the CD idea I may charge a dollar to cover the cost of the CD and postage to send it out!

Foamflyers Site


Hi Jeff,
You have done an excellent job of setting up a personal site. I will pass the site info on to our local club as you have provided lots of good info.

I too would like to see a plan of your latest project & I presume best electric flyer. Even a 3 view with a few dims. would work for me.

Thanks,
Bob G

Foamflyer, where in the Mojave desert are you? Anywhere near Palmdale. I'd like to get togeather if you are near by. Love your plane and the single aileron idea. Never thought of that but can see how good it can be.

I would enjoy your cd! If you were to guess, say, 2 ailerons were 1" x 4" each, would you double that to make a single or 75% or? Thanks Jim. Ps thinking about using this on a p38 to save trouble!

Crash & Burn, I'm North of you. PM me and we'll work on something.
jimkirley, I almost always use the TLAR method. It depends on the wing area.
More info later....

What type of material are you using for your hotwire templates?

Variable- I use posterboard for hot wire templates. They're inexpensive, easy to cut, and they can be used repeatedly with care. I have quite a collection of airfoils and contours sorted into big envelopes.
