I pretty sure I have seen Barts red Pathfinder plane fly a few times. It has a very strong corner. Bart Kaplinsky has the unique abilty to hold virtually any stunt ship extremely steady, whether his or someone elses. Having watched,(and judged) Bart's flying a number of times, I can tell you that, I can see no reason why with current equipment, Bart can't be in the top five Walker Cup finals, at current and future Nat's.
He has a VERRRY steady hand!!
