this a real rr1?

I'd say that is real. I have read that the very first RR-1s didn't have the ribbed tank or crankcase. (This could be a rare one). I'm not sure if the seller would want to mess with it as it looks pristine, but you could ask if they would take the tank off or remove the cylinder to take a picture of the rotary drum.

I'm not sure that it is real. While the early ones had the silver case I am 99% sure that they still had the ribbed crankcase and tank. Also the other thing that looks suspicious is the filler tube on the backplate. These typically didn't have that since it has the 'stunt-style' tank.

Looks like the gold cased RR1 he is selling is legit, but I would have him take a picture of the inside before spending that kind of money.

Yeah, I could buy it and send it back if it isn't real. I might ask him to check but now that you look at it and notice its in a package and all, it is most likely real. I'm not actually a collector of these cox engines, I collect old toys and interesting stuff so I don't know if I really need one quite like this. I'm thinking about getting one that has the ribbed case and tank just because its the more common one that people would remember. Thanks for your guys' input on this.

Huh, Matt you have a point there with the filler tube. I might just stay away from this one and it looks like he is selling 2 of the same one so it very well could be fake.

I have bought a NIP Golden Bee in the past that had the filler tubes in the backplate, the tubes weren't drilled all the way through. I have never seen a RR-1 without the ribbing but I have read about it in the past. I don't quite remember where though. The only way you really can tell is to take a look inside to see if it has the correct parts.



Well, I stand corrected! In the 1992 "Vintage Toy Collector Handbook" by Tim Dougal, Chris Swanson and Yvonne Ottomas. Under the manufacturer "L.M. Cox, Cox/Leisure Dynamics...." the RR-1 is listed and is described "to have either a plain "silver" ribbed crankcase or gold-yellow ribbed crankcase with blue ribbed tank. None are known to ever exist without the crankcase and tank ribbing. The RR-1 .049 was made 1956-1963 (stocks in storage lasted till '65)......"

So according to the book, it must be fake or one that hasn't been known to exist up till now... The book was written in 92 so who knows what has been changed now that info can be found easier on the internet and people can connect.

I cant find anything about the book on the internet. It includes many other toys and all the cox engines and models.

Yeah, I know there were very few with the filler tubes. Seems Cox liked to mix parts quite a bit so who knows for sure.

Your right about opening it up. It would be a neat engine if it is in fact real!

Matt.

Like I said, I'll just pass this one up. I do have a question though. Why are RR1s so rare is they were available for 10 years? I know that the first version Tee Dee .15 was only made for 1-2 years and those don't sell for hundreds of dollars and they show up quite often on ebay. The QZ .049 was made for less then 10 years and those don't sell for very much and they can be found easily.

Yes I stand too I have just on mh aerosols and they show that the crancase and the tank are ribbed on the silver version so either this is fake and is near worrhless or is reap and different and in that case is near priceless well almost.

Maybe people started taking them apart to use the high performance on other engines or maybe cox did limited runs of manufacture of them.

I don't know about that. I have a friend who has a RR-1 on his plane and he claims it only puts out about 15,000-16,000 RPMs. I always thought they were considered rare as they were not the average Cox engine, most kids would have only gotten the Babe Bee or the Golden Bee since those were the cheaper engines. The RR-1 was more expensive and was most likely bought by adults for their models. The time period they were made and discontinued also can play a role. Also they are different from the rest of the Bees, they are colored differently, have ribs and don't have a reed valve so that stands out to collectors. The product run was also probably limited since the demand probably wasn't as big then.

I heard of a guy getting 22,000 rpm out if one and now that I think about it rear rotary valve cox engines always were expensive

Looks like someone is bidding on the RR-1 now...

Hopefully it is real for the sake of the bidder, but I am still leaning no. Did anyone ever ask the seller to open up the engine?

I didn't yet, if you don't want to, I could ask. I don't know if "beer guy" did or not.

The buyer will not lose any money if it is counterfeit because he can send it back and the seller must give the Money back if it is not as described I could also ask if no one else wanted to.

my goodness... 550 bucks...for a cox...that is truly insane.
i never thought anyone would bid with a starting price of 500...

Rr1's are worth a lot of money but I have seen .010 nib go for £180 and and other engines go for more I would not pay that for an rr1 unless u was a collector and it was the only engine I was lacking although I have a new addition to my micro diesel collection the Arne hende .1cc

is that a swedish engine?

Yes why?

just sounded like it...can you post a picture?
