Impresssive. I'm happy as h if I get a sivercan to turn 20 at 1.5. Now I'm assuming for us normal human beings a blackcan one that turns in the 24's with an amp draw of 1.7 or better is a decent motor. I'm not being sarcastic, I'm in awe.

Full disclosure: a silver can that turns 25K has very little bottom end and is useful only on tracks with super long straights and very sweeping corners where you can keep the speed up. Think Memphis in 2003-4-5. At 7.2 volts, a good all-around silver can with good torque will turn somewhere in the low 20's at about the same amp draw. I still prefer a 5 volt reading, however, and at that voltage a good motor will do somewhere between 13-14,000 RPM.

Full disclosure #2: That is not actually my fastest black can. I have an older 'olive' colored one (what we called black can motors before the new ones came out in 2006) that spins about 1500 RPM higher. Because black cans have a little timing on them, they don't lose much torque when tuned for RPM. In fact the torque number on the black can from the picture is just a smidge higher than a good all around silver can. But I still think that's too much power to put into a Mini.

Hey guys, been reading this thread for a while. I know there is an equation for Tourque with Amp Draw and RPM. However, one thing that I never liked about Amp Draw is that it can be mistaken for drag.

Default try it

hi,

try this and see if it works for you...

10 hr motor break in, 2volts, reverse direction (clockwise), periodically stop to spray out the comm, oil bushings (very small drop), keep motor cool with fan

periodically clean comm with spray, then run 2 volts for 2mins till comm is very shiny

8amp charging for 2400nicad batts or 6amp IB4200.

buy the best speedo you can afford. makes a big difference.

gear for punch, not necessarily for top end...

enjoy

Why do you want a 4 slot motor?
Honestly, my best race motors are all 2 slot these days...

Has anyone tested these motors on a Turbo Dyno? If so, what were the load settings used?


I just melted one using typical 27turn motor settings.

the ansmann clash motors are silver cans. just get a couple of the 23t ones and peel the labels off (and they cost less than the real tamiya ones too)

Some do, but most of them have pretty much the same performance as a good 2 slot. The Great Urban Legend is that they are all superfast, but I've not found that to be the case...and I've worked on a few of them

I think he's trying to stay within the rules at his local track...
