Like I said before I am supportive of what the IGT8F is about. The one thing and the only thing that I wish the federation can adjust, is the naming of the "SPEC" class. Instead of calling it just SPEC class, based on the rules as it stands right now, it should really be more specific on naming the "SPEC" class (like "REDS SPEC", or something like that) to minimize confusion for the newbies.
If someone who decided to buy a long chassis RTR then this person will need to buy a new REDs motor, a new REDs pipe, a new REDs header...etc., I hope you are getting my point. Anyway, there is nothing wrong with what you are doing but just name the SPEC class more appropriately and thats all.
Again thank you Tony for making the effort along with others (lots of names in my mind) to make this GT8 class a better class.
