Cox Golden Bee
A favorite of mine. Got two hung on my P-38 right now, original to the plane but replaced in later years by Black Widows thinking an increase in performance, but I really didn't notice any difference in this high drag heavy built to scale not fly model. But it did fly.
Got two more GB's in my display case and maybe more in the loft, but still, I saw a need for another as I recently posted about - Cox Engine Detour or something.
It arrived yesterday slightly stuck but clean. A little heat gun heat freed it followed by a spritz of Remoil. All you guys favorite SPI is evident. It has a thick wall cylinder indicating I guess later manufacture.
It came with a standard Cox 6/3 prop that is badly curved. Is there a fix for that or should I just toss it?

Cleaned up without disassembly, unusual for me.

Good looking Golden Bee. Like other members, got a soft spot in my heart for these colorful engines.

Hello friend, I'm glad you're enjoying your engines !!
I tell you about the propeller, please do the following:
If you notice that the shovel of the propeller have cracks, do not hesitate discard them !!
Put water in a saucepan and boil it, when the water is boiling, turn off the ornalla (without fire) and immerse the propeller there, at least 5 minutes, recover the propeller and by force of hand bring the shovel to the right place holding the shovels to its ideal place until it cools (warm tempered).
Repeat the operation again (if necessary three times).
The propeller will be new!

Re: Cox Golden Bee
Hey Bob, Congratulations on sourcing another Cox Golden Bee engine! I have a soft-spot for them too! I've mentioned this countless times here on the forum.. but will mention it again because the post-title would warrant it.
I have "two" Golden Bee engines that were in my family since new. I don't know when they were purchased though. They are very different. Originally; the Golden Bee was configured as a Cox Babe Bee .049 engine with a stunt-vented tank of 3cc's larger. They had an air-intake of the same (.0625") size.
In later years; I found that one of them had a much larger air-intake. The engines had been taken apart.. and parts "mixed" with other reed-valve engines.. so unfortunately I lost traceability to the cylinder-porting between the two. I'm guessing that the cylinder-porting differed between the two.
Here's a couple of photos that compare the two tanks.. and their backplates..

![Cox Golden Bee Golden11](https://i.servimg.com/u/f62/18/50/45/90/golden11.jpg)
The photo-example(s) show an enlarged air-intake on the right-hand side examples. When measured; it is .082". This has baffled me. This engine was not modified by my family. The gold anodizing can be seen down the throat of the venturi.. so it was not drilled-out.
My theory is; that some "later-model" Golden Bee's were hopped-up by Cox.. just preceding the release of the higher-performance "Black-Widow engine.
My example is probably very rare.. but you never know with Cox.

I understand your reasoning I did that work many times because here we do not get any nucleus and / or some accessories, the results of "test" were always good, that's why I shared my experience.
Therefore, comment that if the propeller is inspected AND HAS CRACKS, it should be discarded.
The hot water allows to return to its normal creation position, it is not damaged.
I have repaired many propellers even in wood, but hey, we are faced with different situations. Here, where I live, it is not easy to obtain materials, so you have to investigate and see how you can solve something, if you can not, it will be there in oblivion.
It is an experience of your own nothing more ... do not take it, you may have many alternatives to solve it.
