Basically a 1.20 size plane at about 10lbs flying weight.... for 3D

How about a 20cc profile with removable wimgs? http://www.swanyshouse.com/index.aspx I have the primo with a 20cc RCGF. Any flyin style is no problem and wil hover all day or shoot for the moon. Definately would fit in a car with the removable wing's.

I'd look for a Ultrastick 1.20 lite. They don't sell it new anymore, but you should be able to find one used. I have a Zenoah 20cc engine on it, but it's just a tad underpowered. A 26cc would be perfect.

I agree with those who are saying a ten pound 3D machine needs 30-35 cc and it is hard to do ten lbs with a heavy model engine so engine weight is important.
I enjoyed very much the comments by ahicks about wing area. Last winter I designed and built a plane to use some surplus wings meant for a 100cc plane, which were 86" plus round tips added ten inches for a total of 96". It weighs 16.5 lbs and is powered by a MLD-35 and is an absolutely fun plane to fly for many of the reasons that ahicks points out. It does wonderful aerobatics and flies smooth. It climbs vertically to very respectable heights for hammer heads and spins. It does large loops and great axial rolls and will knife edge from horizon to horizon easily with very little coupling. When using flaps it seems like the landing approach is in slow motion with the nose up and a little power on for a great shallow slow glide slope. It is not a fast flyer... but flies graceful.
The maiden video shows its character somewhat though keep in mind that no flaps were used on the landing as the elevator mix had not been set yet. Also keep in mind that I've reached geezer age and was not looking for either a 3D plane or one that was fast.
