New RJR "C" can

[PDM1]

Well Monty this will save the long distance charges, congrats on the forum.

Have you worked at all with the new RJR c cans?

How will the strength of red dots do in this can compared to a Kelley?

Thanks

Paul,
I've built about 50 of the RJR setups now. They seem best suited for modest powered tracks and/or heavier cars. They aren't quite as gear ratio sensitive as other setups, and are quite rugged. The plating is excellent.

On the downside, they are still a gram or more heavier than ProSlot thin cans or the Kelly can. The endbell aligns well, but care must be taken as the hoods tend to be uncomfortably close to new, full-sized comms.

Like all C cans, they work a bit better without the magnet clips. Like the other setups, it is therefore highly reccommended that you brighten the inside can surfaces with your favorite abrasive before gluing the magnets in place.

In my experience, Mura red dot magnets can be found in a broad range of strength, covering the full range of Mura magnets in general. The 'red dot' designation indicates that Mura has at least approximated a decent match in any given pair. The individual motor builder, working from a large sample, can definitely do better. If what you meant was which can produces the greater field from the same set of magnets, its fairly close but the RJR, being almost twice as thick, gets the nod. Remember, though, a stronger field is NOT always better!

I have a question..... Why are the motors better without the mag clips? thanx......ben.....

Ben,
It seems to be a matter of field shape and also freedom of air flow. All I'm certain of is that its true: I've seen before-and-after testing on a variety of motors.
