RE: U Can Do 3D
Purple, the horizontal stab is removable. I could fit my UCD in my New Yorker by setting the wing in the back seat and sliding the tail forward between the two front seats. With the removable elevators you should have much less difficulty fitting the plane in your car.
Coomarlin, I think you're right. On the 46 UCD you can see that the tail is much lower than the 60 size.
