My J3 is finally done, except for a few adjustments and clean-ups. I have some pics to post.
I know the ailerons are warped; that's one of the adjustments.

How much differential are you guys dialing in to the ailerons anyway?

Thanks for your support,

Duke

I may buy the clipped wing, just for fun (although the big wing gave me coniption fits - warping after shrinking covering. I used Solarfilm, and I think it was a little intense for this light a wing frame.
The maiden may have to wait for Spring; it's usually quite windy this time of year here.
After I finish up a few odds and ends on some other models of mine, I'm going to start the floats for the J3. I already have the GWS floats which I think will be OK, and the streamlined alu. rod. Now I have to pretend to be an aeronautical engineer.

Nice job seawolf! You like Navy eh? Here is my large Cub done up as a WWII NE-1. This kit looks nice although I would probably finish it in Coverite Tissue for a doped fabric look and use the same scheme as my 1/5th scale below.

Well, I had to go back and see why I posted that..

A bigger version would definitely be nice, but I still have to get the L4 done and then get onto a Super Cub before I get lynched.

The trip to NEAT wasn't good on my models, so I have to get a bunch of stuff fixed up, or build new ones. The Cub is starting to show some wear after 200+ flights and poking screwdrivers through the top of the wing.

The Clipped Cub got fairly damaged right before NEAT and even more banged up on the way there. I'll still "patch it up" for a flying model, but its days as a show model are probably over. Danged it, just not looking forward to doing all those checkerboards again...

Tank, the last time I spoke with Brian about models he had in process, he told me that the L-4 is definitely underway. Same wing as the J-3, with a new fuselage. He was working on the area around the rear window, which is large and therefore doesn't leave a lot of structure there. He was redesigning that area of the fuselage and looking at various construction materials to make sure it would be sturdy. So it is in process.

It’s easy for me to empathize with Brian’s design effort. I am building a 1/5th scale L-4, and dealing with the same issues. Carbon-fiber and fiberglass tubes, as well as plain old spruce dowels are being considered for the cockpit area - - not yer usual model J-3 stuff.

The windows in an L-4 prevent using the typical wing-fuselage structure normally found in Cub models. The only spar in the real L-4 is just behind the leading edge of the wing. (See pic_149) There is no convenient spar on the C-G. As it turns out though, the wing only needs functional struts and solid attachment to the fuselage at the root.

But therein lays the challenge. What remains of fuselage structure must be strong and stiff enough to keep the root rib where it belongs. All those tubes in the full size L-4 (~1/4” to ~1” in diameter) apparently work. (See pic_122 & pic_142). It may be necessary to use bolts or some sort of pins to keep the structure from coming apart in flight.

FWIW, the specific L-4 that I am modeling is on display at the Evergreen Aircraft Museum in McMinnville, Oregon, literally under the tail feathers of the Spruce Goose. This plane was beautifully restored to flyable condition with the markings of an L-4 that flew at Normandy. It also won first-in-class war bird at Oshkosh in 2007. You can’t see them in these pictures, but there are some clever extra touches in this exhibit: a pack of Lucky Strikes, a Colt 45 in holster, and a picture of Betty Grable’s backside, as well as a canvas sling for the rear-facing observer’s seat. You can just make out a copy of “Yank” magazine on the shelf to the rear in pic_122. Also – note the cable behind the wooden spar in pic_149. That’s part of the pull-pull aileron control.

All together, I have about 100 photos of this and two other L-4’s in another museum. Just PM me if you would like any.

Hi guys, I have been building my MM Cub over in the scale fun/kit/plan build , thought I would post some pics over here and ask a couple questions , on the 400XT did you guys have to shim out the motor so it would clear the cowling? It looks like I will have to. I have been reading thru this whole thread and I had a little trouble with the wing warping to , I staightened it the best I could by twisting and heating with the heat gun . The scheme I'm going with is the Navy air ambulance and was wondering if anyone nows if the finish was dull or did it have a shine to it? I plan on spraying it with testors dull coat very lightly ,I know wieght is an issue.

Thanks,


Glenn
