Silver Can Motor Tips/Tricks

So, now that I've read all these tricks, should I build a slave motor "dyno" - hook test motor to a slave motor and measure volts and/or amps off the slave - or should I just drop $100 for a real dyno????
Or, buy $100 worth of silver cans and keep the good ones?
Opinions?
Recommendations on a real dyno?
Thanks.

Wow...this silver can stuff sound like a lot of vodoo. If I were to run silver can, I would do the following: If it's a big race, I'd run with high-quaility bearings with all of the oil and grease blown out (maybe add a microscopic drop of oil), make the car as light as possible, find a setup with high corner speed, and charge at 10 amps .

$100 will only get u a motor checker (eg. TMM motor master, yokomo MMS, integy v2 dyno, etc ..).
those are not dyno as they measure the motor RPM without load.
the "motor checkers" are useful for comparing your different motors but nothing more beyond that.
- it will tell u motor A peaks at 25000 rpm and motor B at 29000rpm (and at what voltage that happens)
- but it doesn't tell u the length of time it takes to hit the peak (just exaggerating - motor A takes 2sec to hit 25000rpm under load, but motor B takes 8sec to hit 29000rpm under load)
- so u get a 1-dimension view only
if u want a real dyno then google on robitronics dyno, CE TD45, fantom dyno. they'll cost in excess of US$500 though

my suggestion is to get as many motors you need to so you can use one motor per race, then swap it for a clean one for the next race. keep them SUPER clean, with a shinny com, it will go dull after a race and needs to be re-cleaned.

Tekin dyno. Haven't been made in years but you can still find them here and on eBay. I'm not selling one, but here's a current posting:

These are the best Mabuchi motor testers ever made and the only one I use on my own bench.

Wow .. that’s really an old school dyno!!
But being a tekin product .. I’m sure it works.

Hawk- It's very stable and produces repeatable results, which is very important to me. The slave motor lasts forever (I use a mod can with a stock arm in it and hard brushes) and once set at at five volts and 15 amps of load you get real-life numbers that mean something in TCS racing (e.g. not too much load and not too little). You can also put a switch in between either of the slave motor leads and get a lighter load reading. It really works. Next time you go up to Trackside, ask around- there are bound to be a few of them in the pits. Or try to hook up with RC GaryK, who's somewhere in IL and might be able to help you out.

Howzit guys,
Has anyone tested the Robitronic dyno? Any good & value for money?
Cheers,
Vance.

I built a very effective motor dyno for pennies, I also did a full article on it, will post tonight.......use you motor to drive another motor used as a slave measure the volts produced with a dvm, the faster its driven the higher the volts, dead simple and accurate, works on all motors of course not just silver cans.
The only secret I have found with the silver cans is the cleaner the comm the faster they go, WD40 and cotton buds used between each run helps, I also water dip......
