If ANY of that were true Mike answer one simple question---- when the guys with "puppy dog" programs got out dated by the new Retro Hawk--remember-these were motors that WERE being rebuilt and worked on---there have been guys selling their ENTIRE program--and MANY--had over 50 motors in their stable!!! So WHY did they need SO many motors??
THERE IS NO SUCH THING AS ANY ELECTRIC MOTOR BEING EQUAL IN HORSEPOWER!!! All it will do to try and go with an UNSEALED motor---is make it a LOT more expensive to race!! Same old argument--- HO is NOT retro!! Try racing box stock 12's---motors that are COMPLETELY assembled by the builder---you'll find it just becomes an ARMS race instead of just a motor race!! Sadly--it doesn't matter if you build the motor--or bolt in a sealed one--only at most %20 MAY be good enough to race--%50 will be good for practice or breaking in tires-- and %30 will be just plane JUNK! Not worth putting in ANY car except maybe to practice with on a flat track!! It's the nature of the beast!!
Sadly--the best way to keep people from cheating--is ENOUGH rules to catch them with--and punishments when they ARE caught!
Yes the motors will be still different, but instead of being pulled by 10 ft on the front straight, you are being pulled by only a couple of feet, now will you be more interested in racing on the king?
As good a driver as you are Tim, you will be back up with him at the lead on... now how fun would that be?
Take the spoiler off the cars, run less spray glue, make the driver drive the car even more... that will make the motor even less important
