I also posted this on Stuka.
Going through a big box of Cox engines, I came across this.
It's new but I'm not sure of what model. Is it the RR1?
What was it intended for? Any value?

I think it is a RR! high value on the bay.

Yes this is the Cox RR1. Besides the outward appearances, you might think it is another reedie but no. The RR designates it as a rear rotor induction engine, the rotor driven by a pin in the crankshaft. Since it is a rotary valve engine it won't start backward like the other cox reedies... Unless you have a left hand rotor, which will only run in reverse!
Like Most other Cox engines, it was made in mass quantities and many exist though in smaller numbers than the reedies of course. Very collectable, but condition is important. So is packaging if you got that too.
I wish I had one!

I thought for a moment I had one.....close, but no cigar. But I wonder what this is? I won it at a raffle in Topeka, a very neat little engine. dg

In 1960 (I think), I saw Dale Kirn do three stunt patterns on 1 oz. of fuel with one of these, flying a Baby Flite Streak on a 50-foot Monoline. It was very cool.

Bob, I think I need to back up bit on my identification. Indeed it does look like the RR1 but could be a clever copy made by a talented machinist. If you were to sell this and it turned out to be as copy, I would not want you or myself to be in trouble had you taken my word for it. Chances are it is the real McCoy just based on the numbers of chance but I advise you to get a second opinion from someone who can examine it first hand.
Because they are valuable, well I would just play it safe.
HypercolorNC does some really nice machine work and anodizing: http://hypercolornc.tripod.com/hypercolornchobbyanodizing/id5.html
though I would not say it would pass for an RR1.
Dale, Not sure what you have but I don't think the final result came from Cox. Looks like an exercise in anodizing possibly done by Mr. Wiltse or another craftsman: http://hypercolornc.tripod.com/
Reminds me of Auburn University's school colors orange and blue. That could be coincidental.
While I have seen a number of colors and color combos, I have never seen a bright green anodized version. I just think that would be so cool, so long as it never came loose and landed in tall grass...

Thanks for the information, Robert. I checked the link you provided and my little motor is surely a product of this company. Mystery solved, for me.

After looking at the copy on the other link, I say this is a real RR!. The front part of the case on the original is simply to big to be a fake. The copy is obviously turned from the standard case.

I agree with this post.^^^^ y1

I just found this!
Vintage Glow Engines has been having some fun with anodizing too! See picture
VGE is also offering an interesting engine partially made with some NOS Cox parts and some new parts. For more details you can see one on $bay Item number: 350291380684 A youtube video can be seen here: http://www.youtube.com/watch?v=jsV65Xhbcz8

You could take a peek inside and see if it's reed or rotor.
-
Robert,
Thanks for the post.
Yes, I do all my own anodizing of Cox parts myself and a couple of other Cox resellers on ebay have me do their work also. That listing of all the crankcase is some of my first anodizing a few years ago and have some blems in the finish. All my current work is flawless that I produce. If any one would like to have some custom work done please let me know. You can find more information on my new VGE RR2 on the ebay listing. I will be adding another video of it turn more rpms' with up grades.
Also as per the other post that is a true Cox RR1 engine and not a repo.

Thanks to all of you for the usual great feedback. #^ #^
Even though the RR1 may be valuable, I do not plan to sell it but rather to donate it once the Brodak museum is up and running. I think it will fit in nicely to a rather large display of Cox engines, especially in light of the influence Cox has had on CL model aviation. y1
A long time ago, I read somewhere that Cox even experimented with some .29 and .35 size engines but they never made it into production. I would like to see one of those on display but I'm not sure if any prototypes were made or even exist. :'( :'(
THANKS AGAIN!!

Bob, they did make some prototypes, someone posted a pic a few years ago...I THINK it was a .40. Can't remember the details.

Some how or another I remember Charlie's Hobby Shop have one of each of the .29 and .35 Cox engines. Do not remember who bought them. I didn't find them in the Meriwether collection. Maybe Dale Kirn could be contacted about this as well as Larry Renger.

Let me just say: YEEEEEHAAAWWWWW.........I just got the best deal I ever had on the first cox .15 I ever owned........less than 30 bucks o2oP! Can't hardly wait to put in on a plane! #^

Great video on youtube, by the way.....I swear I could smell the nitro ;D

Medallion by Cox are great little sport and stunt engines. If it wasn't for the integral plug head. But, now we can get conversion heads that do work. You just have to play with them a bit. But, standard plugs are getting sky high.

K&B/MECOA is making and selling new standard compression Cox glow heads.
Their site says High Compression coming soon, but I think it has been saying that for a year. :)

Cox International has heads too.
