Foldable FT Versa Wing

I like planes that are easy to carry (less than 80 cm wing span), but I also like planes that can handle some wind. This is how I adapted my FT Versa Wing for portability by making it foldable.

First I used two firewalls to make a solid bottom for the motor mount.

Only the right side of the motor mount is glued, for the other side I drilled through the two plywood pieces and added a screw and nut.

On the bottom side I filled it in with hot glue to keep the nut in place.

I placed the front binder on top of the wing spars to get as much strenght as possible. Added the same type of screw and nut setup as in the back.

The finished plane with blue and yellow packing tape.

It's currently running a 1260kv 140w motor with a 3s 3700mah battery. It's about 650g AUW. I'll probably change that to a more powerful motor in the future, but it works okay for now.

It's a bit back heavy, partly because of the extra material in the back and partly because the motor is placed a bit too far back. It works out just fine for me though because I'd like to use my heavy 3700mah 3s batteries.

After about 10 flights and a few crashes the two screws still holds the wing together.

Edit: One thing I would do if I where to build it again would be to remove the paper on the bottom and tape directly against the foam as the paper loosens after a while. The plane still holds up quite good after another 15 flights or so.

Love this. I always have a hard time getting everything in the trunk, this could solve that for me.

Fantastic idea mate. I'm thinking of doing something similar. I wonder how it'd go with a removable spar going through the wing? You'd get a bunch of extra strength, less chance of folding the wings in a high g turn.
