You guys are driving better. Smooth throttle and keeping up corner speed instead of on off trigger finger lessens spiking the battery. Same with not hitting things and getting stuck on the boards.

Can't believe this thread is still going strong--even with the advent of 21.5 brushless approval in TCS races. The only thing I can contribute is what a few of us did in 1997-1998: take a Tamiya black can motor, a dremel polishing wheel and 3000 grit sandpaper and you can have a damn fast "silver" can motor:-)

You know, I'm not sure if that was a Sport Tuned polish job or a 10 year old doc/red dot special that I used for RCFIA--I had a bin marked "Tamiya TCS 1998" with about 8 motors and picked out two and they both were fast. I sold all the slilver can motors on Ebay after that season's F1 race to two different people and they both asked where I got the motors from and if I had any more

Haha that's why you made that helicopter looking thing with the dustbuster. You liberated the "silvercan" from it. Lol. J/K

Wonder what color that handheld Dyson cyclone vac is? Hah. Clean the Ozite while you race.

Nah Sydey, the DustBuster had a generic, plastic end bell, garbage can in it. Swiffers use a real Mabuchi that's difficult to identify, save for the very faint laser etching where it says "RS 540SH 7520" instead of just "RS 540SH". I have occasionally seen a 4 digit code on regular cans, as well. It was something like 6527. First two digits are wire size, second two are number of turns.

A Silver Can motor is the Tamiya #53689. The rest are sealed end bell, brushed motors with a Silver colored can. Polishing the black anodization off of a Sport tuned motor has been tried many times and does not result in a Silver Can motor. This is more commonly called "cheating".

Also, Doc did not market "Red Dot" motors over 10 years ago. His foray into building motors commercially was more recent than that. My guess is that the "fast" motors you had were the legendary "4 slots" which were legal for TCS racing years ago.

The 540SH motors, although they are supplied in some kits, are not legal for TCS racing, but may be legal at the club level. There are any number of "fast" mptprs with silver colored cans, but those came from the world of Spec off road cars.

Lol my head is spinning. Too many "silvercans" with too many numbers. Hah. 4 slot 2 slot red dot no dot. Haha. As long as everyone is having fun it's all good.

Trying to figure out if I got myself one of the 'good' motors. Kit motor, Mabuchi RS-540sh.

Ps, read through the first 20 pages of this thread. Apparently a clean motor is a fast motor. Water dipped my motor clean, used thin oil on bushings. She's sounds great.

The 540SH motors are down 1-2k from the #53689 Johnson, which is the Silvercan motor used in TCS racing.

The can and the end bell are different. The brushes are also different. These are the obvious ones so there may be others.

Nothing wrong with your motor, but unfortunately, it's not one of the "good" ones.

Thats a Mabuchi. Johnson will have a logo stamped in at the pinion end of the can. The Mabuchi will likely have some very faint laser etching on the side of the can. (Photo has been enhanced for detail)
