Very sleek Matin. I love the alignment fixture tooling. Is this something you put together just for the Zephyr or does it work for most PSS, and non-PSS planes?

A couple of people including myself have expressed interest in making a detachable wing as well and if you have pictures of this process (although "not a mystery" as you put it) it would still be of great interest to some of us with far less building experience.

Bolt on wings are quite easy to do and can be done for pretty much any plane. The only difficulty is when the wing is mounted in the middle of the fuse (like the Chaos). Then you really need to do slide on wings with a joiner rod instead of a bolt on wing.

But for bolt on wings just put some plywood plates in the fuse, and install a couple of blind nuts. The biggest area of concern is where the wing bolts go through the wing. That area really has to be beefed up so that the bolts don't pull through the wing making a real mess in the process.

Thanks Brian. Sounds good, and I look forward to learning the process when the Zephyr Fever comes to SoCal this Summer.

I can vouch for the need to reinforce the wing.... also, use nylon bolts. A large impact will shear the bolt off leaving your reinforced wing ready to fly again.

Or the front one will shear and the rear one will tear through. I did not reinforce either my Cobra or Zero enough and they both suffered the consequences. Repairable, but a PITA to do so.

I've build them both ways, with bolt on wings and as one piece birds. The bolt on wings always seem to suffer more on hard landings. The fuse cracks around the plywood plates or the wings get damaged where the bolts go through. However in extreme impacts they often fair a little better, and the wings are more likely to survive with minimal damage. Most guys that fly tight formation stall turns will not go with bolt on wings. There's too high a chance of losing a wing in flight from a minor midair. And at Fermin having your fuse turn into a wingless missile is a very bad thing (cuz they sink!).

So both ways have advantages, and both have disadvantages. The only time I prefer a bolt on wing is if I am planning on traveling with it. Otherwise I prefer a nice solid one piece plane.

If you are really bad at landing then a bolt on might save you a few broken wings (at the expense of a few cracked fuses).

Funny you asked. That jig was put together under 5 minutes 3 years ago and was supposed to end up in the trash.
As it turns out it has a life of its own and has so far aligned 6 planes (PSS and non-PSS) and is holding up pretty well. It is made of reject aileron stock that we throw away regularly.
I even gave it to Dan to use and throw away. And it STILL came back!

I'll dig up some pics of how to do the removable wing shortly.
