The solution to no tampering with the ESC or Motor is Liquid Contact Indicators (LCI). Simply add the fluid to the indicator itself, put on the inside, and if you try to open the motor, it turns blue ( or what ever color the manufacturer wants). Comes attached on the inside from the factory, no way around setting it off if you try to open either. You could add indicator strips for easy visual verification at races.

However, many different things are killing USGT, and RC racing in general. Creating tamper free parts won't fix that.

But it is hella entertaining to read.
