Trinity(Epic) motor's arent as picky as those other motor's that are all actually assembled at the same factory.
Orion&Peak(Top),Reedy(Yokomo),and Integy(Atlas).
The material used on EPIC based stocks comms are simply a different compound.
On a BIG track like that alot of guys favor the
Putnam Greens.Not as much torque as other brushes but good watts and probally the MOST RPM.
Hurricane Golds,Reedy 767's,or a list of trinity's work GOOD but not AS good for big fast flowing tracks.
TRIBO: I do NOT use this product as a comm drop but simply to make the brushes and comm last longer and it does increase effiency.
You CAN NOT use Tribo if you plan on or HAVE used Comm drops on a particular Comm.Use a VERY small amount.Like 1 small drop on the comm itself before a race.
In mod motor's the amount doesnt matter but in stocks it does.
Goodluck Racing guys.
