Default endbell color.....?

When you purchase a kit you get a motor that has a white endbell......if you buy a replacement motor off the shelf the endbell is black.....? Which is which ????? One has 3 fingers on the brushes the other has 2 the kit motor breaks in really fast if you water dip it(3 finger brush seats real quick )!!!

The white/silver endbells with large serrated brush sides are Mabuchis. The black endbell motors with the concave brush sides are Johnsons.

As mentioned above, if the box says 540-J, they're Johnson motors, and are the currently sold type. Mabuchis will still be found with the older kits, as newer ones now come with Johnsons.

They both have two large vent holes, though some older Johnsons have 4 smaller vent holes.

I think I want to "correct" you that Mabuchi's are found in older kits. THis is because there were two of us running newly bought Suzuki minis and both of us got the M's and almost got disqualified as it came with what was thought to be HPI motors.

I guess with this topic coming up, it kind of clarifies that the motor that I got is indeed from Tamiya. Found myself confused as well And I guess new kits still may come with the Mabuchi's

Really? That's interesting.. They must be just getting rid of what they have left of their mabuchi stock or something..

I just figured the 540-J's are all they're actively selling, including in the newer kits..

It's a not TCS legal but we use a homegrown closed end silver can. It has more punch and rpms(about 10%) than a Sport Tuned motor and has a built in cooling fan. They're fins built around the armature and force out heat as it spins. You can really feel the warm breeze coming out the vents. Weather gets pretty hot over here and these motors never get super hot like our old Johnsons/Mabuchis or Sporttuned ones. I have sent a few out to members in this forum and they really like this motor.

Yes, and it's overachievers like that who really SHOULD be playing in another class. Playing BS games like that really defeats the intent of what the Mini class is all about. Yeah, I'm not so naive as to believe is doesn't happen, I just find it sad that it probably does.

This is taken from the Canadian TCS rules:

3. Kit type closed-end bell, silver can motor only. Motors must not perform better that a 1.3amp draw at 2volts on a Peak or Orion Motor Performance Monitor. Motors will be checked throughout the race day. This is being done to tighten up the racing and encourage new racers to join this low cost type of racing!

This is a great rule and should be copied throughout the world in all the TCS classes that use a Silver Can Motor.

The only thing is, to get the amp draw numbers for other dynos from Trinity, APS, Muchmore ect. This is so we can have a standard rating. Not everyone has access to an Orion or Peak Motor dyno.

when the test is done do they put a break in fan on the motor? or is the test done with not load on the motor at all?

Thanks,
Larry
