With so many of the said motors out there, it would be ridiculous to tell thousands of racers that they can't race them any more.
The motors themselves can only be timed so far,before they are inefficient .
The speedies are more of an issue, but any kind of control over them will always be gotten around.
It only took the aftermarket tuners a few months to crack the Nissan R35 GTR e.c.u.
Nissan said it couldn't be tuned,they were wrong !! I dare say that they spent a little bit of money trying make theirs hack proof.
Much more than any rc company will ever afford.
Get out there and have fun. Stop trying to reinvent the wheel and improve what is THE BIGGEST INPUT to your car's success - Your driving !!!
Drive the wheels off what you do have and stop worrying about everyone else.
Regards,
Fleety - nobody racer.
