Wanted WANTED running tips for the RR-1

So I got me a couple of RR-1s and you what I want to do.....

They are your typical used versions and it is time to bring them to life.

I am tired of just looking at the little engines.

It is time they become "The little engine that could."

So beyond the typical cleaning and tuneup, what pearls of wisdom will the Cox Engine Brain Trust pass on????

I ran a SEARCH and, as usual, it is not strong for me on this topic.

In fact, I got nada when I tried various combinations of RR-1.

What do I need to know beyond what the user guide tells me???????

On the L/H side of this page is an Info section which includes engine manual downloads, I believe the RR-1 is included there Shocked

One thing I have found that helps with search is click on Google instead of Inside then Go.
I have had trouble with Inside search lately.

According to that article in the June 1959 Flying Models magazine, the RR-1 had respectable power. It is showing 0.092 BHP at 18,000 RPM:

This is on high nitro Cox fuel (25 or 30%?). In contrast, the Golden Bee put out 0.062 BHP at 14,000 RPM on 15% nitro. cheers  Beer Cheers  drunken

Interestingly enough, two decades later, the Bill Netzeband designed Testor's 8000 reed valve engine produced the same BHP at 18,000 RPM on 15% nitro fuel.

So, I guess if the Cox RR-1 is out of reach cost wise,  eBay
then opt for a good Testor's 8000 engine. lol!

Don't break it especially the rotor in the back that is turned by the crank or you will have a display model in short order . There i am going to say impossible to get with out purchasing another engine Sad Have you tore the engines down to see what you got ? Use appropriate fuel 25-35% Nitro 20 % castor and the right prop not to overload will help and don't just let it scream on the bench if you do that run . Small Cox Logo

An interesting original sport design posted in Oct. 1958 Flying Models Magazine is based on using two RR-1's in a push-pull configuration.

Outerzone: 54" Tandem Bomber (oz3386)

Today if I were to build, would probably consider decorating as a Canadian Bombardier in fire fighting colors, used to dump copious quantities of water to douse forest fires. It resembles that type of plane. Also, if rudder only using today's radios, I'd extend the moveable rudder to the top, doubling its area for stunts. A bit out of the unusual plus larger, it would be an attention setter wherever flown, including S.M.A.L.L. in Arkansas.

And, if one showed up at a flying field especially with two RR-1's mounted, given their rarity as hen's teeth

would be an extremely rare sight to behold. Damn! This Site Rocks!
