You can place things like rules in place & in the end people will get butt hurt.

So what is a good starting point? 13.5, 10.5?
Either of those I can boost into the stratosphere...
17.5 doesn't belong in a SCT, I TQ'd two weeks ago on one, but it was just stupid.

Does my 8.5 look fast? no
Does it come off the track at 180+ deg? no
I think 98-128deg on a motor is perfect.

Put motor rules in place & then there had better be weight rules too.
I'll gladly get an uber battery & hot charge it & then see where that leaves you...

Some people are rule benders, have no rules & it is always a fair playing feild.
