2 Piece Pickle

Doesn't everyone wish they had a 2 piece Pickle? One they could take apart and carry anywhere they want? Then put it back together and fly it when the time and place is right? Noel and I have been kicking this idea around for a bit and we finally had a window of time and brain bandwidth to get moving. This one won't be Skinny, rather a stock 2 panel Edge wing from the last batch. Great care will be paid to attention to detail so that this one flies absolutely as well as possible for a homebuilt model.

We are basically following the Oleg 2 pc Taboo style build but with the angle cut. We started with carbon tubes and used vaseline and release film to lay up outer concentric tubes over these.

The layout for the wing was drawn using a sharpie and the slots for the outer tubes were routed and cut.

Then the outer tubes were glued in the slots, one piece to be cut later when we cut the wing.

This is a great idea Greg. Two piece wings will be more common as airlines get more stingy with baggage.

Nice thread title! The title alone sets a very high bar for the plane.

This is neat Greg. +1 to Mike.

Following with interest-implementing into a solid core molded wing should be doable at low weight penalty.

Made some progress today. Got the spar channels routed out and the spars glued in. Made the tubes for the wing posts. Be ready to bag shortly. Then start on the tails.

Here are other photos (somewhat belated) from the building process.

Working with Greg on this project has been and is a rewarding learning experience beyond "stick-n-tissue" building. We're enjoying this winter building comfortably inside on a flat maple table and our long, flat granite kitchen island when it's too cool in the garage. Greg is an experienced long-time student of model aviation generous in sharing as well acknowledging and giving credit to other's contributions and developments.

Wing attachment tubes

Using the same technique as making the joiner tubes, we made the wing mounting tube. Perhaps this series of photos gives a little more detail on Greg's precision tube fab technique. This photo sequence shows the unwrapping after the epoxy cured, i.e., the reverse of the assembly.

Can you elaborate slightly on the joiner tube / wing tube process? (or maybe it's been explained in another thread?) From the photos, I'm seeing Glad wrap as release film (over Vaseline?), roll on the wet carbon (uni? weight?) and wrap with electrical tape (backwards?). Is that about right?

Tube rolling

The tubes are made by starting with the actual inner tube as a form.

Then vaseline to allow it to release.

The wrap about 2 wraps of Accuply 10 release film over the vaseline and tape the ends with blue masking tape.

http://www.accuply.com/accuply10.html

Call them and tell them you are setting up a laminating line and would like a sample of their material. They will send you a small roll that will last years. They don't really sell in small quantities.

Always in the same direction wrap the carbon cloth. Uni works well because it bends easily in the rolling direction.

Finally follow with the electrical tape. You want the stretchy kind, and pull it as tight as you can. Epoxy should ooze out of the edges. Once it is kicked the whole thing should release fairly easily. The fit will be really tight.
