Speed, he's looking for a "first build", not a second or third. If he want's more capability, just lower the wingtips and add ailerons and now it can do some basic aerobatics. IF he was looking for a plane that is aerobatic capable right out of the box, I would have suggested the Astro Hog or Kobra, not a Kadet. He hasn't even said if he's flown before or not so the Kadet was a given as a first plane either way. How about we leave it up to him and let him see if my suggestions are what he wants and not try to have him reinvent the wheel
