The above airplane, the Airhogs Acro-Jet (actually what you see above is the new version called the Green Alien) was my first RC airplane. It is made by AirHogs and I think it was like 35 dollars when I got it. This plane was such a joy to fly. I flew this thing ALL the time when I had it. I had it for a long time and then gave it to a nephew who still flys it to this day!
It was a 2 channel plane that banked left and right by slowing one motor or the other down. To climb you gave it more throttle. It was very small and light but made of very durable foam. On windy days I would stick a dime or penny on the nose with a rubber band and it could handle the breeze no problem. Talk about a floater! wow. It really could hang in the air for a long time on very little throttle. On a 15 minute charge I could easily get 30 minute flights. I have always dreamed of building a replica of this model about 5 to 10x bigger with hobby grade electronics and a cam. It would be PERFECT.
Then this morning I found this!! Its not BIG but its bigger and beefy looking. It even has landing gear!

More info about this plane
I still want to one day build my own version of this airframe - but BIG. Maybe 80 to 100" span with good sized motors. I have been reading a lot of about shaping foam for RC airplanes, and it really seems like something I want to try to tackle. I don't have a CNC Hot Wire Machine, but who knows...maybe I could even find help here at the community to the parts cut.
If this project interests you at all, please let me know. I could use all the help I can get!!!
One question I keep asking myself.... Would it be ok to use the same type of turning system (slowing one motor) or would it be better to use rudder or ailerons. Same thing for pitch....do I stick with something like my old airhog plane that had to throttle up to climb, or do I want to use some kind of elevator? The thing about the old airhog was that it wasn't all that nimble. It made wide turns, and using throttle to control altitude was challenging if you wanted to fly low. I wished for elevator many times!
So...what are your thoughts FPV Community!?
Let me know.
Ok so I did some research today on all kinds of things about this and similar airframes. Some how I stumbled on this (dont ask me how).
I was looking for Canard airplane designs (I have loved the VariEz since I was a kid) when I found OMAC Lasar 300
It is pERFECT

OMAC Lasar 300 Facts
Here is the patent information for the fuselage:
A single aft located prop aircraft having an X-axis in alignment with the line of thrust of the aircraft; a Y-axis transverse to the X-axis, the Y-axis being in parallel with the length of a single main wing; and a Z-axis transverse to the plane defined by the X and Y-axes. The fuselage exhibits Y-axis symmetry about the thrust line and, in addition, substantial X-axis symmetry about a line defined by the forward edge of the main wing. The fuselage assembly includes a substantially conical cone, the cone having its root at the beginning of the pilot's cabin, and the cone subtending a vertex in the range of 15 to 20 degrees. The fuselage nose possesses an X-axis length to Z axis base diameter ratio in the range of 2 to 3. The aircraft further includes a single main wing secured on top of the upper fuselage in which the XY plane of the wing is in alignment with the line of thrust of the aft-located prop. The aircraft also includes a tail fin system itself having three separate tailfins, one of the fins directed downwardly in the negative Z direction and perpendicularly to the plane of the fixed wing. The second and third tail fins of the tail fin system are disposed respectively symmetrically about the XZ plane of the aircraft, each of those fins disposed at an angle, relative to the plane of the fixed wing, in the range of 30 to 60 degrees.

This full size OMAC Lasar if you look at the specs can carry a NICE payload. I am going to do my best at building this in Foam to be used as FPV platform. I think it will be SUPERB.
I love the high wing design, the one pusher prop motor - its perfect.
Your thoughts oh wise ones?

Huge Resource - Canard RC Discussion
I have read nearly all the pages (I just got in the 200's) in this thread. WOW what a treasure trove of information. rcgroups.com is a great site. I know a lot of us here also post there.
Finally a usable airfoil? still looking![/b]

in response to that youtube vid posted above- we have a Starship at the Evergreen museum in McMinnville (new home of the Spruce Goose) and I always wondered how they got it... I never knew the rest of them were to be destroyed at an Evergreen wrecking yard....
Hi Aaron!
The Spruce Goose has moved to McMinnville? That's new to me, thanks for this info
Thanks for linking this video, interesting info and I added to my favorites!
I am a little late but wanted to post here anyway. Glad to see that there is an interest in canard design. I was the project manager and one of the test pilots on the OMAC-1. We were plowing a lot of new ground with the OMAC. We had to learn as we progressed. We had a lot of help from folks like Julian Walkovitch and Burt Rutan but still had to do a lot "cut and paste".
Early on we built an RC model of the OMAC and flew the heck out of it. I still have a lot of the engineering data and pictures and would be happy to share. Email me at jworden568@aol.com.
