What do you guy's think about going that route.
I'm racing on the rug for the first time(touring that is). i might have to try this motor in my crc 3.2.

okay, I will try a set of fbrush. tomorrow. in quilifing. and will also try a 118 spur. but It also depends what the new track will look like. I will also try to align the hood also. (i do have the tool. haven't used it yet don't ask why) I might try red and red. or maybe red+and green-. what do you think? I was also thinking on picking up a set of 767 with the cavities or am i just wasting mymoney?

Hi Andy...........I'll be going brushless on this weekend, no messing with comm,springs or brushes

I`ll be giving mine a run for the first time this weekend..
Should be interesting...i`ve only tested it up & down the driveway & it feels very punchy.
Another club member will be using one for the first time this weekend too, both got the Pro`s, he`s running a Pro 4 & i`m running a FTTC4.
Cheers

Can you give then the gearing you used on the FTTC4 ?
Thanks.
Thanks.

I played a little more recently with differing brush combinations on both a CE and Fantom dyno and here were the best two setups I found for the co27:
For high torque on tight tracks: F-brushes, drilled face, shaved trailing edges (+) purple spring (-) purple spring, bent just a tad softer
For high rpm on open tracks: XXX brushes, drilled hole (+) purple spring (-) red spring
Both setups gave similar overall power, but the difference in rpm and torque were pretty clear.

After a bit of help from EAmotorsports
me & another pal over here in the uk have got our`s flying
the said track is indoor rubber on carpet every thursday night
roar 9.1,9.2
monster 8.6.8.8
co27 7.65 this is on my evo 4 sorex 28r 64 pitch gear`s
this works out 4 teeth more on pinion then i would on monster
i did go down to 7.4 it was real fast but got a bit hot
on thursday i was flashing for FTD & setting fastest laps during 3rd qualiy
till the dreaded `sshakess` came into play
but this motor is resembling very much like the p2k2 of old so gearing is going to be crucial for this baby to go
luckly we have been using the monster for so long we have a starting point on what ever track we are on
not been outside yet
but on a faster more open track a guy with a roar was in front couldn`t catch him (indoors again)
paul had red/red F-line`s
i had red/red then moved up to red/purple F-lines
how good enogh driver.setup merchant am i (you may ask) ??
good enough to know what is horse & what isn`t
i haven`t just come down the thames on biscuit
not much cogging effect either compared to the roar/monster
better motor ??? no not really just another weapon in your armoury me thinks
having a co27t & roar is like having
a C219t & atlas 19t but in 27t , both are very good motors ,if the revvy isn`t working on the day chuck the torquey one in with 4 extra teeth on pinion & away you go

i have 2 co`s
now other pally has one
had 3 meeting with my one`s played alot
1 of these co`s came of ebay ,so i done what i knew best .
never had a issue with the roar`s or monster`s . i used roars indoors on carpet/rubber`s never over heated
but i think this co will have a small gearing window like the roar has
but it`s got a nice blue can to go with my preeeety blue evo 4
i only need a couple of meets to find if it works or not
And what i found is every thing works it`s just applying it at the right track & right gearing

However, the common thought is that the tighter the spring tension, the more torque you'll have and vice versa.
Also note that the XXX brush setups negative spring is red. This would actually have less tension than the F brush setups negative purple spring, even it it were bent inward slightly for "softer" tension.
