What are the different ways can we make a take apart plane with foam wing?   ???

Oh, wait.  You meant "take apart and put back together", didn't you?  Man, sometimes it's just so hard to tell what people mean.  English is so imprecise.

Of the various ways I've examined, the Yatsenko way still appears to be the best. The installation/structure is slightly different with a foam wing, but not by much as Yatsenko wings are sheeted all the same. I'm preparing to do a new wing in this manner over the coming months and will post pictures in due course.

The other really good way, of course is to follow Paul Walker's Impact article. Lots of examples out there with 20+ years of proof that it works.

Alas, the airlines with which we deal have restricted baggage size so much that now the individual wings have to come off.

Tim is a axe better than a hatchet, longer handle. LL~ LL~  I think I will use the Whole wing method, at lease I know the wing won't fold on me, it's just to transport it in a car to meets. H^^ H^^

Spend a few days searching this forum and the others on take apart construction.   I keep thinking of how we do radio control planes and wonder how we keep them together.

I'm reviving this thread because it's asking exactly my question, but doesn't seem to answer it.

I'm starting the "over-thinking" stage of a LA-46-sized Impact. My econbox will barely fit a Twister, so I'm thinking that I need to either build it take-apart, or I need to drive my truck to every meet.  With gas around $4.00 per gallon, that could get expensive.

I can build it take-apart with a one-piece wing, and I can see how to do that.

Are there any good threads out there that show in detail how to build a two-piece take-apart foam wing?  Is it even done?  The usual two-piece take-apart setups are designed to work with spars, which the typical foam wing lacks.  I'm not seeing how to concentrate the stress that's distributed over the wing sheeting onto the two points that the usual take apart system offers.

Also, what do folks do with their control systems with take-aparts?  I can see how to do it with a one-piece wing: just take the elevator push rod loose after you get the wings off.  But what do you do with the two-piece setups?  Do you have line clips in there, or what?

If there are any good threads or websites out there that show everything please feel free to point to them -- I'm obviously missing something.

Larry W.

Are you coming to the Goyet next week end? If so, I'll talk to you about glider wings and our take apart methods. Strange that the CL community hasn't adopted a similar system.

Cheers, Jerry
