The MMS is very good. Compact, light weight and easy to use. Also, if you race at night, the backlight is great.

There is a little bar that bounces around on the display that basically tells you how badly the brushes are bouncing and arching.

if the comm is perfectly cut and you have brushes that are pretty old or worn the condition meter will bounce around. I use it to basically tell when my brushes are broke in after I cut the comm and install new brushes, when the bar stops or barely fluctuates the motor is ready to go. I used to know a Randy Barnes from toledo that used to run the old TARCAR track, is this the same Randy?

Does anyone have a picture of this whole system and where can it be purchased?

Also, I already own a Turbo35 GFX, do you think it is worth getting this Yokomo motor maintenance system aswell? I'm never really sure if my brushes need replacing or not or if they're broken in, it's mainly just a guessing game when I replace my brushes.

Thanks

There's pics and a description on www.yokomousa.com in the electonics section. Any hobby shop in the states can call Yokomo USA and get one. Yokomo has alot of nice electronics but for some reason they don't seem to advertise them. I'm using their BCS single charger and love it, it uses the same case as the MMS so it's nice and small and uses the same swivel display.

Do you guys think it's better than the Team Much More motor tester? If so, why?

Matt I will tell Bill you said hi, I see him all the time. This unit sounds pretty nice. You said you use the charger as well? you like it? I was thinking about buying some of the yokomo electronics, but I have never seen any one use them.

Hi guys. Greetings from Malta.

I use my Yokomo MMS all the time.

Like Matt said, it's useful to bed in new brushes and know when they have bedded in.

What I do is take readings at 5 volts, 6 volts and 7 volts before a rebuild (just as I take motors out of cars) and after rebuilding.

You won't believe the difference in revs after a rebuild.

Also very interesting to compare motor advance and different brushes.

A great bit of kit. I don't know what I used to do before I had it ..............but that's the same way as I don't know what i used to do before I had so many things!

Regards

Joe from sunny Malta.
