The wing tips fold under and it looks like I will just barely be able to get it all in my car. Thats my plans anyway.

I have piano hinges on the bottom. A single bolt on top locks it in place. I'll try to have more pictures as things progress. Honey do projects may impeed the progress. Working on it when I have time.

RE: Lazy Bee scratch build
These pdf files are all I had for plans. They were found on one of the forums and I blowed them up with a projector and traced out on poster paper. I am not set up to make kits and to make full sized plans would be much more difficult for me then the actual building.
Also, some of the things I did would scare most modelers. The only balsa I used was in some lite ply used for planking. Everything else was just scrap wood laying around the shop. Titebond III wood glue was my best freind.
Heavy - yes. It remains to be seen if I can nurse it off the ground. If it fails, well, with the big wheels I might have a nice land rover.

My first break in the winter weather to go outside to take pictures.
About 80% constructed - about 50% complete.
This has been a fun project. If flying is as much fun as building, this should be a great year.

If you will allow me to say, that you are a fabulous craftsman. Thank you for sharing your wonderful work with us.

RE: Lazy Bee scratch build
This has been a very busy spring for me and progress has been slow.
I did manage to have some time today to do some ground testing without the wing. Checking out the radio, ground handling, radio interference from ignition, etc. everything seems to be ok so far. I do enjoy the big wheels.
The engine has to be spun for starting. I am using a simple homemade starter from left over weedwacker parts and works well.
I am using a Troybilt 29 cc 4 stroke weedwacker engine (borrowed) from a brand new machine. My first engine leaked too much oil.
Still got some finishing touches to do before actual flight testing and thisall hinges on how much time I have to work with.

Well, the reason is that I am a real lousy builder
, I'm trying to get started in building before flying. I don't yet have the tools to actually build the plane like I should. I have an X-acto knife, a ruler, a file, some sandpaper and glue, lots of glue.
There are a lot of imperfections in the ribs and I was able to camouflage them by sheeting the wing, I realise when I finish the plane, it will be heavy, nothing like a real LB.
But I have an old OS.40 in stock, so I guess it will have plenty of power left over.
Anyway if it fails to fly acceptable, I will be able to say that I learned a lot. Then I hope my next build will be more precise.

Glad to see you building rather than ARF'ing it and scratch building from plans as well!

Yes I do have a bungie cord suspension with the big wheels typical to the Lazy Bee build. Not sure it is needed but it allows a little more forgiveness on the landings.

RE: Lazy Bee scratch build
Itook my Lazy Bee out to the field today for some testing. The big wheels may have to go. Nice ride but they are causing it to ground loop at just below take off speed. Back to the shop for modifications.

RE: Lazy Bee scratch build
I feel that I should report the good with the bad.
I put on new wheels and I had no more problems with ground looping.
I waited for the perfect conditions with no apparent wind. Lift off was smooth and looking good. Gust of wind hit it, ballooned up, stalled out. Some pilot error could be involved also.
Not nearly as bad as it looks but it will be early fall before I can work on it again.
Sorry folks, not the end of the story, just a little delay.

RE: Lazy Bee scratch build
Dang sorry to see that. Your right it doesn’t look bad. Trade off for building light and actually when a heavily built model tip stalls at 40 mph on the landing final you have just as much damage to repair. Glad to see your fuel tank held in place and didn't punch threw the front cabin.

Ouch!
Like you say it's not as bad as it looks. For the new guys out there, when this happens set it aside for a week then look at it, it's very repairable.

That is a heart breaker. You'll feel better once it's back together

RE: Lazy Bee scratch build
It comes out to about 25 oz per sq ft. Wing loading isn't the whole story as larger area wings can handle larger weight per sq ft. Cubic loading is more important. Mine figures about 7 which is about the same as a trainer.
Part of my problem was a wrong prop. I needed a longer length and flatter pitch.
The plane is nearly repaired. Making some other changes. I am building a counter balanced elevator.Should be ready in a week or so.

Down elevator would bring the tail up sooner.
did you try giving a little up elevator to get the tail up sooner?
good to hear he is excited about repairing. crashing is half the fun! = more build time!
