Hi Jimmy,

Thanks for the photo. I don't really want to put that much stagger
in the wings on the bipe. The instability must be due to the vertical
CG? CP? I'll try a little stagger and put most of the weight under
the bottom wing and see what happens then. Should the two wings
have the same incidence in relation to each other? I have the top
wing with a little more dihedral and a slight pos. incidence. Maybe
I have it backwards.

--edit--
Just took the bipe outside for a test glide and I moved the
balancing weight on the top wing to under the bottom wing.
That pretty much solved the instability problem. At least it didn't
try to roll off to the side. So with motor, batts, and servos on the
bottom wing, it should fly ok. With just a little extra work maybe
I could make it look like Orville & Wilbur's bipe.

Has anyone thought about sending the designer the RC videos? I'm sure he'd love to see the results of his work ( that is, of course unless patent litigation isn't a factor)

Also, there's something incredibly soothing about watching that wing fly compared to other indoor flyers. I can't wait to see more from you guys. Given some time I'd love to try a hand at one myself.

Plans


This is a autocad drawing I did for the ducted fan wing.
It is in R-14 & R-2000

Good luck

PS
Still plan to make a small cover on the bottom center to cover up the radio and batt.

Got some new pictures of the ducted fan wing you might want to see.

Gary Jones was in Springfield and I let him fly it while I took pictures

He said it flew great. But the man might have lied.

autocad flie for air surfer


Dear SPFD,
Nice photos of your plane! Do you have an autocad file for the design? I have been building my own just from the same outline as you. I have plans and flight info for the unpowered version at:

What version of Autocad do you have.

Larry

I just looked over the thread and saw I had posted the autocad drawing about 4 post back in a zip file.
Let me know if it does not work

Yes Vince
You don't want everybody to think that you don't like airplanes.
If it flys, its has a beauty of it's own.

I SWEAR, I did not lie! Your wings are GREAT flyers, and I want to fly them again. They also look cool as HECK!

Vince,

Thanks for bringing some more NEGATIVE into our lives. We certainly NEED it. You are such an inspiration!
