Trinity doesn't have them available for sale....
Even if they did, they would not be legal for racing at any ROAR event.
As for motor designs.....tell ROAR to remove the stupid rules saying how we can build a motor and you will see motors that last longer, run cooler and give better performance for a similar price. Right now though, we are stuck on magnet type, armature size and type....makes it kinda hard to build a motor that you have little hope of getting legalized.
My company is in process of designing such a motor...
