I just ran across this plane that is based on wood strip geodesic construction. It has good performance numbers for its day. Was wondering if anyone knows where the plane may have ended up and if there is any detailed doc. on it?

I have been a KitPlanes subscriber forever but don't remember this article
in the May 1988 Issue: Midwing Motive (Thalman T-4), May, p. 36.
By Don Dwiggins

I contacted KitPlanes for a back issue info but they have not gotten back to me. But from what I read on their website all back issues were destroyed in a fire and electronic archives only exist for recent years.

Would anyone have this issue and be able to make me a copy? I'd gladly pick up costs.

Blue skies,

Tom

I have an EAA publication(How-to series Wood volume 2) that shows construction drawings of the Thalman geodetic and other geodetic airplanes.

Thanks; I will check the EAA website to see about a copy.

But I would still like to find the KitPlanes article.

I heard back from KitPlanes; they don't have the article available. So I sure hope someone has a pile of old KitPlanes in their basement.

It's not from a basement, but my EAA chapter has a copy of the May 1988 issue. I checked it out from the library and will happily send you a copy of the article if you still need it since Kitplanes doesn't have a back issue available. PM me with an email address (I can get you high-res jpegs pretty easily) or a physical address if you want photocopies. The reason I'm posting here is in case someone else is interested... in which case it probably makes some sense for me to turn it into something smallish that can be posted here.

I would be interested if you can post it here.

P.S.
You might need permission from Kitplanes, I would think they would allow it since it's not available from them.

Good point, I wouldn't want Jake to get in trouble. I think I'll hold off on posting the pictures until I have someplace where I'm the only one in potential legal trouble...

Hello BBerson,

Any chance for a copy of the information of the geodetic process from that book? I can grant you my address (Lynnwood, WA) via PM if you are able.

I've been interested in this type of building for some time.

In appreciation,

Brian.

I can't help you with finding the issue but nice airplane. has the same windshield over the top cowl like a Hiper Bipe. The Hiper Bipe I used to fly I put a layer of ceramic wool under the top cowl to give a minute or two in case of an engine fire.

Is there any real difference re an engine fire. If the fire is above the cowling, I really doubt that the windshield will help much...

Blue skies,

Tom

Thanks for reviving this thread. There would probably be thousands of Thalmans flying around today if the man had not flown into a snow bank. Such is life and history...

If you have a chance find an old edition of K.D. Wood's book "Aircraft Design." It was self-published and pretty rough in terms of page layout and writing but it has a few pages on geodetic design and construction for aircraft. It is about two or three pages of a discussion about how it is built and how to analyze the structure. If I remember correctly it is not easy to do an analysis of the entire structure. It has been done before though. A Vickers Wellington has a geodetic structure in metal. It does seem like a cheap way to build an airplane. The diffficult part would be to cut all the strips. If you get more into researching this you will run into a number of books that the EAA self publishes. They will have a book titled "Wood" with articles on wood aircraft and then have another book titled "Wood Aircraft Construction" with the same articles. I was researching geodetic construction for a while and found that the same articles you have were published in two or three of the EAA's books. Check out K.D. Wood and look at Fisher aircraft. But there will not be a lot of details.

Geodetic wings that I built during construction. The top of the fuel tank is also the wing skin. Now covered with Poly-Brush on. Pops

By coincidence Duncan ((see Razorback thread) has just asked about details for mid wing construction --this thread has been revived only today also --perhaps someone can forward him some info on the T4(Snowbird) ?

Thanks for bring this up. I couldn't remember the name of the airplane and couldn't find my old EAA woodworking book.
