Not building one. I have a clean sheet cabin plane design that is 80% complete, but I am struggling with the upper cabin and wing attach points (tube Spars). I am about ready to surrender to a welded upper cabin.

To be honest the general engineering on the LMA is pretty poor, I'm only building it because a very close friend gave it to me. I am working on a clean sheet design, using the old drawings just for basic dimensions,but be very interested in seeing your design. Also looking at the Badlands Aircraft design, as it suits the Deregulated UK spec SSDR (Single Seat De Regulated). Alan.

I am not going to hijack your thread, so I won't post anymore then this. Mine is very different from the LMA. It uses a conventional tube spar truss wing with full span ailerons. The fuselage is primarily solid riveted aluminum angle with some gussets a few square tubes, some structurally blind rivets and a bare minimum amount of AN hardware. I really don't understand why nobody else has beat me too it. The only part that is giving me fits is the upper cabin. I have a design for it, but it might be too complicated. Going to build a mockup up first and let some people who know more them me look it over.

Think one of the Bede aircraft uses a similar construction, and your wing sounds like kitfox etc, still be nice to see. Or you could consider a 4130 CrMo ,
'cockpit' top structure. Beauty of this hobby is you can do (within reason) whats suits best ref use,design, budget etc.

STOP PRESS !!!! Latest News,
Building will be on hold for a few weeks, we've lost the use of the Airstip & Hangar. The new owner ( The old owners son ) needs us off the premises as
"he can't get a mortgage on it with the aircraft there', ????
We have located a corner of a huge local barn, but there is no/limited option to fly in or out, so just clearing the hangar out, a very sad and annoying situation !!!

Have him tell the bank that the revenue stream for the property (and thus the mortgage) comes from the people renting space in the hangar and using the airstrip, and would the bank rather their customer have an unstable, unreliable revenue stream - or a stable revenue stream?

A local turned his dads airport private. Keeps airport designation but keeps planes away. Kicked out the planes and plans on parking semi trailers on it.

He went to a domestic property mortgage broker, not commercial, but he was so adamant that, we were the problem ? that even if he allowed us to stay. none of us want to anymore. End of an era , but start of a new one, such is life. Homebuilding in the UK is hard enough, but we will always find a way to keep up our hobby.
( As it involves the original owners son,there is a "family issue" that the sons mortgage money needs to resolve. 3 guesses what that may be 🤔 )
were all collateral damage.

Tough when your hangar-lord gets nasty. We just got a 9% reduction in our monthly rent by just offering a 6-month lease. It's that old bug-a-boo = supply and demand.

I just stumbled onto this thread, as I was researching the LMA aircraft. I hope you are able to continue, as I'm enjoying the build. I just recently purchased a LMA LM-3X... alloy framed fuselage. It was basically finished, but never flown, and changed ownership several times and was basically stripped for parts before I got it. I have the shop, the tools, and the drive to see it fly someday.............. hopefully soon! I'm guessing by next spring, it will be airborne. I'm not impressed by the design, and the wings seem a bit lacking, but I'll be making some changes. Information on the LMA is hard to come by. Again, I'm enjoying your build. Thanks!!

Hi Mark, Like you I have found the core design 'lacking' in many areas. We decided to almost ignore the "build manual" too many words, not enough drawings or photos. The wings are like you say look fragile, so we made a proper D-Box. thats made them more stiff. I may consider canning the project, as another venture may be acquired, but let me know if there's anything you think I can help with. Where are you based, guess the States??? Alan

I just saw this from May. I didn’t get notifications that I had anything.

I’m in West Virginia. Pretty mountainous terrain. I have a farm, and I have one ridge top that I can use as a landing strip. I’m very mechanical, and with this being somewhat built, all the hard work is done. I look forward to talking more.

I'm planning STOL as well, but plan on drooped wing tips, a larger tire, flaps, and folding wings for convenience. The flaps will also give me the clearance I need to fold the wings over the fuselage. Not planning on losing any wing length, but I am planning wing tanks, and lose the header tank to compensate for a larger engine. Running these things through in my mind, and they seem to work out on paper. Time will tell as it gets started VERY SOON!! With yours originally being a side by side 2, your width is 34"?? Do you have in your plans book, a print of the fuselage with some dimensions? If so, could you post it here, or pass it along to me? I'd appreciate that very much. I'm wanting to widen mine, and may go a bit wider than 34", Mine is 29" currently. AS for VGs, I know it helps on the lower end, but what does it do to the cruise speed? Much change there?

Hi, Mark. Visited with Fred McC. of LMA in 1991 and still have some of his propaganda on file.
Felt his planes were innovative in the square tube-and-bonded construction area, but "shade-tree engineering" as well. Nice fellow though.
Daughter married a WV boy from Morganton.

I’ve lived in WV most of my life. I’m sure I’ll die here. WV is a beautiful star, but for pilots, not much flat ground. I always say, if you want 1000’ of grass strip, you better have a big yellow piece of equipment.. lol. I have about 475-500 now with minimal leveling, and may take it out to 600. With enough engine and a few changes, I’m sure I can get in and out of the farm. I would never fly this plane as built. Just too much on the marginal side for me..

This project is NOW FOR SALE, its located in West Norfolk, Great Britain.
Since losing the Airstip and Hangar the build team has disbanded, so the LMA is looking for a new home ???
If a 'build Partner' want to get involved, then a 50% FOC share could be made available, PM if interested.
