That's the beauty of the rules Dible & I concocted -- the ARFs are allowed & encouraged, but not required. "Custom builds" like the Toni have to be just a tad bigger and heavier.

Why go to the trouble of building a custom job? Because the ARFs aren't clean enough or snazzy enough to suit you. But guess what, you won't be able to blow them away. Somebody who chooses to bring out an off-the-shelf Shoestring or Midget Mustang can still keep up ... just like your Shoestring can keep up with my Toni.

Look at other threads on this forum and you'll see the conniptions guys are going through with the "one-design" ARF events. Example: Can I add carbon fiber to the wing and still call it stock? What if I take a stock wing, strip off the covering, and add full sheeting to smooth out the rib bays? Is it stock then? None of that with F1 Sport. Make slick Rickey Rat out of your Shoestring if you want, but you'll have to add 50 squares and 4 ounces to be legal.
