Testors Fly'em Props Wanted

The (originally) four bladed prop is for the Spitfire. It is the one with the long hub and is the problem child. The three bladed is for the P-40. It does NOT have the long cowling, so I could use a modified Cox (the shaft is bigger on the Testors). I cant find my ruler, but they are both about 3.5" diameter. Pitch?? who knows, but it is small. No markings on either one.

I think an acceptable replacement for the P40 would be Bernie's .020 three blade 3.125 x 2.5. I could go bigger. Testors did have a "Speed and Stunt Kit" that included a bigger prop and longer lines. But I think I want to keep it on the short lines: sometimes in the city finding a "field" bigger than 25 feet is tough.

I might have a few of these somewhere....just gotta find the box the are in and that could take some time.

Opinions are like elbows...everybody's gonna have a couple...I'd look at using a spacer, 2-3 washers, maybe aluminum, or a nylon spacer like the ones sold in hardware stores, and use a cox prop 5x3 three blade or a 5x3 and 20' lines
Years ago, I had some correspondence with "Wild" Bill Netzeband, who had done some design work on the Fly 'em series. He said props were made to "detune" the performance, i.e., slow it down. Why they just didn't suggest longer lines I don't know, possibly less chance of loss of control.
p.s.
I thought I had photos of the performance props on my computer, but can't find them, I did upload them to the 049Collectors site under Testors Fly'em file

I thought about using a spacer, but the prop shaft isn't long enough. It is hard to see, but if you look at my last photo you may see that the hub is hollowed out. The hollowed out area gives just enough shaft to get the nut to bite. When tightened, the nut is fully inside the hub, and the end of the shaft is flush. Can the threaded shaft be removed and replaced with a longer one???

I'm sure the props detune the engines. An 049 with a decent prop on ten foot lines would turn sub-second laps! I want to keep one of the birds stockish so it can be flown on short lines. In my neighborhood, finding a place to fly can be tough especially on the weekdays. On short lines, half a basket ball court will do.... or if it is raining, a parking garage

If you have spares, I'd love to buy them from you. And take your time: the longer it takes, the longer the old gals stay clean

Rod.

That sounds just like the one that I bid on and lost out too. I was bidding for the same reasons, I need the main gear and tail wheel for mine. Yes, it was missing the tail section and I agree, the rest looked good. I think my bid was in the low $30's.



That P-40 has been chasing those Zero's for weeks now, but as he has no landing gear I can't bring him in.

I apologize for stepping on your thread John

Looked through my box of props and all the 3 blade props I have are Cox. Nothing with the tabs left on the hub as shown in the pics above.
