Motor spring tension

Does softer or harder springs give you more speed?

I'm using an Epic binary2 10 turn.

Thanks.

More timing gives you more speed....but lighter springs will give you more top end and stiffer springs will increase torque.

Thanks, I went to softer springs, but wasn't sure if it would give me more speed. I'm also running 25 degrees of timing.

Maybe turn it up to 27 or 30 degrees. Then put on slightly stiffer springs to compensate for low end loss. Should be dialed.

I thought you already had the motor dynoed to 64,000 rpm?

Keep heavy springs on your 10 turn, and make sure you cut the comm every several runs.

I clean the comm after every run (each run is a few second long) and I cut the comm quite often.

Thanks guys.

You probably dont need to "clean" the comm after every run. In fact, it might do more damage than just leaving the motor alone in between cuts and new brushes.

This is why I don't use brushed motors. To much work.

Keep us posted AJG - Let us know hwo the motor performs after you get everything back in the car.

Well, if top speed is what you are after....I would not use a heavy spring.....try to spring as soft as you can without the comm buring up from too much arching. Remember that the if you overspring, the brushes will act as a drag brake and will limit your top speed.

Well, thats a pretty big spread.....not to mention a purple is the 2nd heaviest trinity spring....try a red on the positive and green on the negative....possibly even see if you can run a green on the positive...continue to spring up both sides until you get slower. I would never be more than one color apart either(though you can bend them a bit to get a little more or less if needed). The positive side should always have a higher or equal spring....never spring higher on the negative regardless of what any retard tells you.

Trinity Springs in order of tension (highest to lowest)

Silver
Purple
Red
Green
Blue
