the term F brush is almost its "trade name", in other words what the brush is known as to the public.

F's would be the fastest, after 3 fast runs they will drop off considerably.

bill at full throttle has F's in stock right now.

Havent found that. I ran a pair in a CO27 without cutting that got at least 10 or 12 packs through, and it got quicker and quicker untill the serrations were just about gone - then it got slower. All I was doing was cleaning the comm and brushes with a comm stick each run.

just curious; what class? in both 12th & 10th stock, the brushes burnt up, lose the lubricate and drop off at least .3 sec per lap. and a large loss in overall power.

the 3 run assumption was an average. it depends on the ambient temp. the gearing, the springs, brush width, a dimple in the face, etc...
it is hard to give an exact answer to "how many runs can i get w/ "X" brush.

Touring stock at 1525g, large open flowing track with hills in it (around 1.5m elevation change) geared at 5.09. Hara speedy with a very very agressive profile. Purple/Purple springs. Full face brush, no timing cuts, slots or holes. No comm drops.

My personal favorite brush is a bit unusual... I've found that the 'ET Racing' brushes from RC4Less are a great all around brush... I've run them in stock oval, sedan, and offroad... I've run them in 19t... They never fail to impress. Great punch, good RPM, and they show more power on my TD45 where I need it for each kind of racing... Long lasting serrations, but they continue to run strong after the serrations are gone -- in some cases, they actually perform BETTER after the serrations are gone!

Give them a try -- you won't regret it!

The ROTM motors I've run with F's would get better after each run, and generally stayed that way not dropping off for some time.

I have been using putnum brushes in the X stock for carpet racing Bule - green + I have found that they are giving me good power I gear the car at 7.5. Just a question why you guys dont recomend the putnum brushes always going for the F lines I belive Putnum brushes to be more consistant than F lines without the loss of power.

Putnam Brushes TQ'd every stock class at the Snowbirds last year, (both oval and on-road classes) as well as TQ'ing and winning both Stock TC and 1/12th stock On-Road. Also Won the Indoor Champs at Cleveland, TQ'd the Nats, TQ'd and Won both 1/12th Stock and 1/12th 19 turn at the Halloween race...
Then again, I'm biased... lol
