does anybody have any experience of these?
just bought a brand new 11x2 for under £25.00 still in packet...are they any good?
does the "flatwire" make any noticeable difference?

Hey Chris These are good motors I have an 8x2 flatwire(not for off road)which is OK.the flatwire is suppose to be a torque motor, they are by all counts quite fast as well. At the track I have seen a few cobalts (mostly 10x2) and they are very quick, If I remember correctly the cobalt is based on the D6 with a few changes to the exterior but not to the rotor & magnets. should be a nice match.

Beware the evil D6........, these motors are very good but need a lot more maintainance than others on the market, skim every run and change brushes they generate a lot of heat and seem to draw more current than other brands
many guys at the club i race at no longer use them

I round off the P94 brush in the D6 with very good result's, at least 5/6 run's before cutting the com and the brushes outlast the com. I noticed that Trinity is now offering a Hex cut brush in the Lemans compound that should do about the same , though I have yet to try them, I run only D6's in 13x1 down to 8x1 in 2wd and 4wd

not sure what you mean "round-off" the brushes?
do you actually modify the profile of the brush so reduce surface contact?

Yes, the contact surface end's up an oval shape much like the Orion V2 brush, that shape or a round shape is why the com's last so long, the P94 brush is too wide anyway { Too much com overlap } The Team Trinity guy's were cutting down the width to standard standup brush width last I heard. Have you seen the Cobalt-2 ? it has oval brushes, but I've heard of problem's with dead short's in the aluminum endbell's.

LMK how it work's for you, mine work great ! the Trinity XXX Hex brush is pn# TRI13507 the Epic pn# is EP1208 and will probably do the same as modding the P94 brush the way I do.

well - i ran it all day sunday, and it did indeed run very hot.
Spoke to Tim Woods, and recommended getting rid of the double shunted brush for a single shunt brush, so I will do this next time out, oh, and using a fan too.
I have not yet stripped the motor down to inspect the comm, but I will this weekend.
I cut down the edges of the brush prior to use - there was plenty of speed and punch all day, and the motor didn't once show any signs of slowing down at all.

I thought I would mention that the late Big Jim Greenemyer tested the brush shunt's used on our brushes and they failed shortly after 10amp's, that being said duel shunt's will handle more power . I've allso notice most all the D6's I have came with 20deg advanced timing IMHO they don't need that much timing and I back them down to 12deg and adjust gearing accordingly, I don't have overheat issue's with them, I should have mentioned the timing but didn't think of it in my earlier posts.
