The two most frequently asked questions that I see in the general VTA thread are:
1: When are other 21.5 options going to be allowed?
A: The only other option allowed is the Ballistic Novak motor with the 21.5 wind in it. That configuration offers the same perfomance parameters as the original Novak 21.5 Brushless motor.
2: When is the Vette going to be made legal?
A: The shell is not going to be adopted into the official list of legal shells. So you wont be able to race it at sanctioned USVTA events like the Nationals. However many clubs consider the shell to be acceptable for their weekly racing. If you want to run the Corvette, then its best to always check with the race administrator where you plan to run. It would also be a good idea to have another shell ready that you know is legal by the official rules.
