that's really nice, and a Saito too,

my Y model was larger, with the MVVS 35 Gasser w/ 3W 20X8 was a very good match, it was fast and would climb out well, so yours should be some 2 or maybe 3 pounds lighter, so it should go very well with the Saito 40 Gasser.

Assembling the 1/5th Scale R-986D from Atwood Aviation which was 3D printed for me at 9.6 inch diameter. I put it together with extra thick CA versus the epoxy recommended by Damon. The 4-Stroke 40cc gasoline engine runs very smooth so I don't think it will get shaken apart. We will see. Lower 2 cylinders omitted for cooling. Sprayed it with KRYLON Aluminum. I need to get some dark grey gloss for the crankcase tomorrow. I am studying the installation and contemplating a baffle, I have to figure out how to mount it all inside the cowling. Leo

I decided to go with a baffle. It is a circular light ply ring that is set at the mid-point of the Saito cylinder. It will guide the cooling air through the fins plus it will provide support to the dummy engine. I will glass it into the cowling when it is done and it will come off complete with the cowl when dis-assembled. Also installed the stock tail wheel assembly yesterday, it went on really easy. It's going to need some black paint. Installed a slightly over-sized tire for better grass field control. Leo

Installation of a servo activated choke on the Saito FG-40. They need a lot of fuel to prime and pop-off. This is a convenient way to do it. Also works as a secondary engine kill in addition to the electronic ignition kill. Hinged block of foam to seal the carb. Leo

This is a really fun stage on the dummy engine. Added some Rustoleum gloss grey for the crankcase. Nice color, sets off the aluminum. Added spark plugs which are just brass tubes and shrink tubing. Went with my own version of the distributor ring location which is supposed to be behind the rocker shafts. Mounting the cowl with screws from the back is always an easier option. This required making 2 new plywood rings that are slighly, 1/16" larger than the kit ring. From the pictures you should see how the cowl mount screws and t-nuts go. Leo

Very nice job! Makes me wish I would have spent a little more time dolling mine up.
Working on a Hostetler 33% Gee Bee Z now, Can't wait to get it done!

Displayed the Gee Bee Z on a table at the last GeneseeRC Club meeting. Pilots liked it but I am not sure they know what they are looking at? I think they lack the knowledge of the Golden Age of Air Racing to know how significant this airplane was. If they only understood, then I think they would have been more excited. Hmm. It must be just me. Leo

Can anyone tell me how they removed the canopy? I know it is attached with brass screws, but it seems to be adhered as well. Also, what size pilot might fit under the glass?

Unfortunately they glued that canopy on, so the only way to remove it is to cut it off. You will end up pulling ultracote with it. I would cut the ultracote around the edge of the canopy before trying to remove it so that you won't have to recover areas like I did. The Williams Brothers 1/5th scale pilot was the largest I could fit in there. I tried the 1/4 scale but there was no way. The overall dimensions on this airplane are 1/4 scale, but the fuse diameter is smaller so it effects things. Paint is on the inside of the clear plastic. You will likely end up re-painting the yellow on the outside as it will get scared up. Leo

This is Lowell Bayles, he looks terrified! and he should.

Mine is coming along. Have glued the wing fairings in place. Soon it will be time for the decals and the engine test run.
