    Sport Racing plane for 3 cylinder Kolm engine.

    I use fans on my Roto 85 because they don't want to restart after sitting for a short period after landing. Temps are fine in the air however.

    Sport Racing plane for 3 cylinder Kolm engine.

    Had a look at the manual, not much there, looks like there's only one temp sensor. I think I would instrument the rear cylinder.

    Scale Wendell Hostetler 30% Piper Cherokee Glass Fuselage Build.

    The mold modification worked as planned, a couple coats of wax and will lay up a new part. It's not perfect but will make an acceptable part, the defects in the air dam are below the trim line so all is good.

    Electronic Carburetor/Roto 85 FS Install

    I had to cut a rather large hole in the engine stand used for the Saito FG61 to get the Roto mounted. When I ran the engine it had quite a bit or vibration in the 3000 - 4000 rpm range. Decided to make a stand for the engine and increase the stiffness. It's mounted and ready for testing.

    Here is the fuel flange for the Super Cub, I would image the J3 is about the same size. I would make it about 7/8" like the photo above.

    Scale Wendell Hostetler 30% Piper Cherokee Glass Fuselage Build.

    While researching the number of screws used in the cowl came across this photo of the bottom half of the cowl. After seeing it I just couldn't leave it alone. Works out well because the current requires the removal of the nose wheel to remove the cowl. alone.

    Scale Mick Reeves 1/3 scale Tiger Moth

    The wing area of the Mick Reeves Tiger Moth seems to be a guarded secret. I found the full scale is 239 square foot, so the 1/3 scale comes in at 3824 square inches, that's a lot of wing! At the advertised weight of 30 pounds, the cubic loading is 3.51which puts it in the glider category.

    Scale Mick Reeves 1/3 scale Tiger Moth

    The 2500 was 25 CC glow engine, ran on low percentage nitro and less oil than other glow engines. A friend had one in a Akrobat II that was about the same size as the US 1000. The Arkobat II had a strange life, a friend's fellow coworker copied the plans and started the build, cut the ribs out...

    Scale Mick Reeves 1/3 scale Tiger Moth

    The US 1000 plans show OS 1.08 to ST 2500, while I'm sure other engines were installed. A 45 cc would be way over the edge!

    Scale Nelitz 1/3 scale Cub build

    Not sure what your "dilute through the fabric" comment refers to but I would not brush the first coat on, go right to the spray gun after taping.
