Default Monster Horsepower Pro motor- Brushes

I was wondering what brushes give the best performance/power for a monster horsepower pro motor?

slingr got it right..I ran nothing but stock for Trinity last year, and that was the best out of anything.

The stock springs on the Pro version (red on +, green on -) are the all-around best for off-road racing.

There's not much you can do to a stock motor..

Make sure the hoods are aligned (Trinity is good about this). Don't break 4505's in before you run them..just put the brushes in, and race. At big races, I cut the motor every run, and put new brushes in every two runs (re-serrate the brushes the second time I run them).

Monsters are very fast for stock motors..the hardest part is finding the right gear ratio. Remember to gear lower than you normally would any other stock motor.

Paul's been running 4499 PNT with purple springs on both sides. At big races we cut & re-brush every run, so we carry extra arms, but he thinks that's the fastest way to set up the motor.

Your thoughts, Aaron??

Purple springs are stiffer and will give the motor more torque, which is what's needed in TC. In off-road and especially with racing on a weekly basis, the red/green combo is easier on the comm (and should allow the motor to rev a little higher on longer straights). Most of the big electric races I've been to in the last year or two, it's been hot outside..and I'd be worried about the purple springs (and extra amp draw) overheating the motor.

As for running the 4499's instead? I'm not really sure..are you absolutely sure they're not really 4505's? It could be because of the purple springs and driving so punched in TC, but I'm not absolutely sure.

I may have the wrong number. Paul runs the ultra high silver dual shunt E-brush. With purple springs the thing has gobs of torque and very high RPM, and Paul is quite competitive in off-road this way.

Hear you won't be at the Mod Nats -- will see you at the Pink Palace in July. When will you come east for some real racing??

When I can meet an East Coaster that can beat me..it seems all the real competition is out here anyway.

Just kidding! Jesse Robbers smoked me badly at Silver State..

Trinity's only dual shunt brushes for stock motors (according to their website listing) are 4500's, which are really hard, and used on TC's and 4wd cars because you're so punched.

4505's will be better for 2wd buggy and truck.

I beg to differ...they offer a 4499PNT which is a dual shunt no terminal 4499.

You are right..I scrolled right over that one.

The dual shunts hold up better when really punched. I bet a dual shunt 4505 would be really dialed..haha.
