Well I've been using Putnam Greens on + and -, I presume that the F's should beat those too.

I haven't run Putnams in like 5 years so I have no idea. I've been running mostly 767's, 4499 cross cuts, or Hurrican Golds.

Okay, fair enough. I am going to do a back to back test with them with EA Motors and Surge Motors (Monster Stock Based) and we'll see how they end up. I'm going to be running on very much a power and RPM circuit so I expect accurate results!!

Yeh, I think I had that happen too. In fact, when I ran at a race meet, I killed 1 arm and 1 can (it was pretty hot day too) and I was using putnams all round. Pretty disappointing since the can and arm were BRAND NEW!!!!

Not to worry, I'll be F-Brush from now on I suspect. :-)

There's laydown and standup versions. I've tried them in Monster Stocks and Binary 2 mag motors and plan to test them in some 19T's soon. I guess a lot of the guys in the 19T A at the Novak race were using them too

Thanks for the data. I think I now know what its all about. That extra edge when you need it.

Too bad that test didnt have like some wear data. But power is good enough.

Also no one answered my question on keeping the motor clean, just kinda got off-topic from the Q but thats cool.

Ill probably print out that data sheet and go into my hobby shop. I think I would get a drop that provides high rpm and power.

Wear wasn't an issue with the dyno tests. For each Drop test the motors got a skim on the comm and a new set of brushes. Also each drop was tried on 3 different motors and the order that they were tested in was changed on each motor (that way comm wear and size would not be an issue). I was pretty anal about setting the controls and eliminating as many variables as possible.

For those wanting to try the "F" brushes they are $1.75 a pr not $3.00 like I see them advertised at some places.Just don't like to see people pay more than they have to.
