Got myself a NOS LMA 'Taylorcraft Kit', been stored for ages but now agreed to build for the previous owner, major issue is no stress data was ever offered/given by LMA in Florida, so building in the UK is becoming a bit of a
problem ? The bonded Alloy airframe is considered non-standard ??? any of you guys out there built LMA's or similar aircraft ?

Welcome to the forums!

I can't answer your particular questions, but you know you're on the hook for build pictures now, right? :gig:

You may find that it is far more expedient to engage a local engineering school to do the stress analysis and/or proofload the airframe as a school project. All of the paperwork, calculations, measurements etc. can be done, supervised by their instructors,a nd then this data can be presented to PFA or whoever to justify their issuing a permit to fly or "certification".

Welcome to the Forum and personally I would rather see hand drawings then Pic. Gives me an idea if the building talent is there.:roll:

Alloy bonding is considered non-standard for homebuilts. What sort of bonding? Tubes? Skin? With or without rivets?

I visited LMA in 1991, and met Fred McCallum. A nice chap, and had thought his method through. At the time he said "No joint failures" on his bonded square tube construction.
Now, Alan, I grant that Hysol is not common, though it avoids the re-heat-treat problems of welding aluminum. I corresponded with Fred through the 1990's.

`Ere we are, Mate! My Yorkshire background (a grandpa's family) showing. Light Miniature Aircraft folder from that time frame.

Probably "thin gruel;' advertising and the like. May be able to answer a question or two there from. Have not heard from Fred for some time - he may no longer be with us. I kinda admired the T-craft-a-like, not being a rabid fan of the Cub. But perhaps could answer a question r two. Will leave folder within easy reach.

Regards, Percy

Hi Guys, ref the LMA construction, Yes the tubes are both bonded and riveted, with HYSOL/LOCTITE 9434 Epoxy from HENKEL. may well have been a 3M product in the past???
Fred is no longer with us, and his son appears from other forums not too interested in supplying bits and bobs, but WICKS still offer plans and kits ? but these may be all wood ?
the LAA don't seem too interested in giving help , so its the SSDR route to get this one in the air. I,ve a LAA inspector visiting later today, but only to see what the kit actually looks like.
Guess that Fred/LMA actually offered to many options, just 1 or 2 models may have been better, and the build video is simply amateur, so didn't really promote the product to well.:ermm:

Latest News !!!!! LAA inspector turned up, had a look at the build process & loved it !!!!! He said if he wasn't so busy he'd join me in the build. so all systems go. Will be the SSDR route as LSA/VLA aircraft in the UK under 300kg empty CAN ONLY FLY AS SSDR ?
Look out for pics soon.

Fred did his designs in both wood and aluminum square tubing, and I have sales literature from that time frame and would answer questions (PM?). May Fred Rest In Peace.
Wick's has stuff: http://aircraftproducts.wicksaircraft.com/viewitems/aircraft-kits/lma-taylorcraft-replica-aircraft-kit But all are the wood designs.
