F Brush vs. 4499
Could someone pleas explain to me the difference between the F brush and the 4499? I put a set into a C0 27 this past weekend after doing all the other little tricks,i.e. centering the armature, aligning the brush hood, trueing the comm, replacing the bushings.
It runs completely different(better) than my other C027 with 4499's or was it just a cummualitive effect of everything?
Thanks

Why would you change the bushings?
Anyway with "F" brushes Purple-Purple or Purple-Red worked very well. Gearing I believe was based on motor temp which was around 180F.
All those things you did are good but springs and gearing is critical when your running "F" brushes!
Just my $2

sorry fellas, still pretty new to all this.
gearing stayed the same at 35/100 in a TC4 on carpet with purple/purple springs for the "f" brushes and the other C027 had red/green with the 4499's as I had been told to do by a much more experienced racer. Motor temp I can only guess at, when I broke it had been run just over 2 minutes of 5 and by the time the main was done and i got the car back it was around 120.
I got the motor as part of a lot purchase and had just redone it since it had been used in a off road car, hence the bushing change.

Unfortunately, if you are running on carpet with foams, your gearing will change and it affects your rollout. May be better to list wheel diameter too or just list your rollout for feedback and questions. A 61mm foam tire will be much different than a 55mm.

Hi all,
i need some help requiring tuning a stock motor. i have just gotten a team orion advantage charger, am i right that this charger will tell me the amp draw from the motor? at what volts should i test the motor. what am i actually looking for? and then how can i improve on the results (or does it not work like this?)
changing springs, brushes, etc will improve motors performance, what do you guys recommend to gain more rpm?
thanks in advance

larry roll out that motor at 1.03 to start at both harbor hobbies and trackside.

Thanks again Wallstreet.
Another question, Are you better off using a larger spur and smaller pinion or a smaller spur and larger pinion. I know the numbers would work out the same but I know there has to be some type of performance differences between the 2 ways.
Would you get quicker acceleration using a smaller pinion with a larger spur?

I have always been told that running the biggest spur gear that fits in your car is always the way to go .... However when running brushless... you run what ever it takes to make the correct rollout

you can get quicker acceleration with Bigger Spur gear mate...
