Noline,

I use the Reedy 767's for my monsters in 1/12 scale with red+ and green - springs. For less maintenance I have run a 767+ and 766 on the negative. With that combo you can go quite a few rounds without having to cut the comm. Between heats just run the motor at 1.2-1.5 volts for a minute and spray the comm a couple times.

For 19 turn if you have standup hoods Reedy 729's are good, if they are laydown then I would use 767's. For srings you may have to go with a purple/ red combo.

Finishline F brushes are also good for both cases.

Greg

noline,

I'll second Greg's opinion on the F brush from Finishline. However, my setup is slightly different for a Monster. I file about .010" off the trailing edge of both brushes and use green/green springs. Filling the trailing edge of the brushes will drop the amp pull slightly and increase the torque with a minimal drop in rpm that won't be missed on the track. This will make for a more overall powerful motor.

I used the F-brush at the Halloween Classic and at Vegas and made both A's with it.

It's a very good brush. I run green/green springs.

One other option you might look at is 4503's they dyno about the same as f-brushes with a tad more rpm, but the amp draw is less. Usually I find 4503's fall off a little less at the end of the race.

I would also look into Putnam Brushes. the green on + blue - they make killer power. check the results from the last few big races Putnam brushes have been taking down many TQ's and wins

the f brush is also a good one

then you can always fall back on the trinity e brush or reedy 767.
