Gary,

I emailed you with the tracking number from UPS. It should be there by Friday at the latest. It went out early this afternoon. Can't wait to see when you get a chance to start on it. I'm really looking forward to pictures as you go. You are an outstanding friend for doing this for me!

No worries Barry. I love to build for others as I can. I have a CJ Corsair waiting in the wings on a spot in our building line up. He wants me to build it and then fly it. He got every option they offer for it I guess. I'll be happy to oblige when we can clear out some other things. Your engine is not so big a project. I'll still have to spread it out a bit though. You know going in it will be awhile, so we are cool.

It isn't too busy with work right now, but that could change. As my construction work slows down, my wife picks up more time at the hospital. I'll be glad to have more work so she feels comfortable taking less extra work.

You are more than welcome to post here. Please, anyone working on these dummy radials feel free to post in this thread.

Really nice work. Love the wire harness. What did you use for the wires? It all looks outstanding. Thanks for posting. Looking forward to seeing more.

Yes I did. I meant to tell you, sorry. What a great site for micro scale parts. I could spend hours looking through it all.

BTW, the picture of the rear bank of cylinders on your radial is a nice touch.

Gary,

Finished my engine for my YA P-47. This thread was extrememly helpful as I simply followed how you put yours together. All I need to do now is some weathering and install it in the cowl.

For anyone out there considering building this engine or another for whatever warbird they are working on by all means build one. Sure it took several hours but nothing was difficult. The results are certainly worth the effort!

Thanks again!

John B.

I neglected to post this one addition I made. As you recall, I had made a silhouette cutout on the bottom cylinder for added cooling. I decided to go ahead and add that cylinder, but make it removable. It is held in with Velcro for static display, but can easily be removed for flying.

I am assembling a Carf Corsair and would like to have a dummy radial that nice. Can you tell me where you got all the parts? My plane is 1/4.5 scale. I would like to have a Moki radial but the cost is a bit more than I want to spend.

Thanks,
Mike

I started mine with a FTE resin dummy. Find one the correct scale, or close, cut the cylinders off the casting, and then go to work. The prop drive housing is the challenge. It so happened that the cowl for the Meister P-47 already has a piece molded in the center that can be cut out and used for this. Without this, you may need to mold one. The rest of the parts are just thinks like aluminum tube, solid aluminum rod, balsa, and various other common things to builders, as you can see in the beginning of the build thread.

Hope you try it and please share your pictures.
