True, but if you want to make any power, you run heavy springs on the (+) and don't give a damn about brush wear.

Thanks a bunch Guys!!! Everything is back together and working just fine. I like the Battery Test, and will use it again Im sure. Now to get the Timing right. Any hints/tricks for getting it just right?

I think I read somewhere to run a heavier spring on the + also, so I did. It scared me a bit when I read the post about running a softer spring. How much difference will a heavier spring make. Im not doing any "real" racing, but I DO like POWER. So would the amount of power gained, be worth the loss of brush life? I know brushes are cheap, but as Ive mentioned amny times, Im a LONG way from any good Hobby Shop.

Are Reverse Rotation Motors marked as such, in case I ever run across one in a Lot or something?

I can't help with that because I'm not a speed demon. As a matter of fact, the Sapphires I run are a little too fast for what I do, which is crawling.

for general bashing around, i wouldn't worry about the springs.... heavy/+, light/-. but for serious racing, you want the most performance you can squeak out of it.

does the can have any timing marks on it?

Just a notch in the center, the endbell has the marks. They are all to the left of the screw. Didnt I read that you turn the Can in the opposite direction of Arm rotation?
I just wonder how much to turn it (12*?).

Looking at a Site that has info on Timing, and found this confusing info.

In the first paragraph it says:
"Also setting the timing below 0° can cause serious heating problems and the motor to run backwards."

In the second paragraph it says"
"Decreasing the timing gives you more torque, longer runtimes, and less heating of the motor."

Which is it?

i really don't know where to say you should set it. 6....8 degrees maybe?

to advance the timing you turn the endbell opposite of the arm.

BOTH.

Ok, starting from ZERO and working up, the motor draws MORE amps as you go, but will require more gear and it decreases runtime. Go below ZERO timing, and bad things happen. The best place to start is a baseline of ZERO timing. The motor will have the softest performance, the least heat, and the longest runtime at that given point.

More timing = more speed, but at a loss of runtime and torque.




My suggestion for anyone not racing modified is to run 0° timing, and forget it. It's really not a tuning aid for novices and will only make your life miserable trying to chase the perfect setup with a gearing and timing balance.

Really?? Until now, Ive always been under the impression most motors "needed" the timing advanced some.

Nope, electric motors don't really need anything... other than voltage.

I wouldn't advance a motor too much past 2-4° for any application, but that's just me. Then again, I gave up brushed motors for racing 3 years ago, so I wouldn't ever have to screw with that crap ever again.

Well, thanks for the info, EVERYONE. I'll certainly put it to use. As Ive mentioned, Ive had overheating probs for a while (on a lot of my RCs), and Ive been upping the timing around 12*. So, I'll turn em all down and see what I can do then.

Thanks again All.
