RR1 engines

Post  WingingIt74 on Wed Mar 14, 2012 12:02 pm

I noticed in the for sale forum it was said that last one wasn't a 1956. How can you tell? There was also a version with a silver case but I don't know much about that one either.

I'll try to get some video of mine to show how the rotary valve works sometime this week.

I guess this answers some of my questions.

http://www.mh-aerotools.de/airfoils/cox_bees.htm


RR1 .049 (0.8 cm³)
Manufactured in 1957-1965 (#390)

At first glance, the RR1 looks like a fancy Golden Bee with small groves on the blue anodized tank and on the nose of the crankcase. The disassembly reveals the twin bypass cylinder and the rear rotary valve intake, which was used instead of the reed valve, typical for the Bee type engines. As you can see on the photo, there was no spring starter. Production ended in 1965 and later engine designs reverted again to the simpler and cheaper reed valve induction system.
During the first two years of production these engines came with a silver crankcase like the first sample shown (1957-1958). Later, the crankcase was anodized yellow which contrasts nicely with the dark blue tank.

The gold anodized engine block came along later and the natural finish is the real 56-57 model I believe.

Some of the pros will chime in and fix things I hope.

Aside from the info on the website above, when taking mine apart, I did notice that it has a different piston, as it has no copper.

I remember (for what little bit my memory is worth) seeing a picture of an all silver one withOUT the grooves in the crankshaft. I think it was a very early model.

I'm not fond of Yahoo groups myself. I'm on the ShopSmith 10-ER group, but it's just a pain since it is more of a email group instead of a forum.

Ditto that. The registration turned out to be a huge maze for me, I never got through it.

I had both versions in my hands a few years ago but they were torn up pretty bad. Set them dpwn and old timer grabed them. Oh well had no use for them anyway. Seller had box full of Cox engines but very bad shape. I passed on all of them. This was before Cox vendors started to sell products.

Dan,

The one that got away.......... Oh well. I bet any parts off an RR1 would be highly valuable.

The funny thing about the RR1 is that it performs as well as the rest of the bees yet it is still highly prized.

I would like to own one except like you said, what would I do with it?

Were any RR1 engines with a muffler, ever sold by Cox?

No. not even. The first muffler was the '66 Quiet Zone .049, Thimble-Drome did made a muffler type speed control for the Space Bug but i don't know how quiet it got and it was an add on.
