Folding wingtips, keep an open mind
Has anyone ever heard of folding wingtips? Just the fiberglass portion.
With careful measuring, the RV-7 will fit in that extra space at the end of a row of T-Hangars, except for a few inches on each side of the wingspan. By being able to put them on a hinge of some sort, and leaving the spars in tact, I can slide it right into the tiny hangar.
This would bring hangar rent down from $295 to $30 per month. A huge savings in rent.
Anyone heard of this? think it is feasable?

I don't know about it from an engineering standpoint, but I really like the creativity of the idea.

More feasable would be choosing to own a 6A instead of a 7A. The 6A has a span about 2 feet less.
Also a small help would be to use teh horner style tips instead of the sheared tips. I think they are a couple inches narrower.

Make em easy to remove by using hinges like on the cowl....
Several guys have started using hinges to attach their wingtips. Makes em easy to pull and remove....

What if you were to just eliminate the Tips all together and just cap the wing off.

I did that and the plane is about 2 kts slower.

Well, ...
I have to admit, if I could save $265/month by removing the wingtips, then I would remove the wingtips even if it costs two knots of speed.
But an alternate approach may be to install removable wingtips. That is what I plan on doing, and there is at least one company out there that sells a product for making the wingtips removable. |

I sincerely hope that you will ALWAYS have 2 people there then pushing in and out. With this kind of clearance, you're just asking for a "dinged" wing.

I have that kind of clearance in my hangar (we keep two planes nose to nose in a T hangar). We solved the 'ding' problem by building small railroad tracks for sliding the plane in - the tracks guarantee we can't hit anything. |
