Skill Or The Hardware???
FYI,
Last years masters was won by Pete Goldsmith flying his design scratch built 46% Cap 232.
As for the discussion, practice and dialed in equipment make the difference. I fly every week with Pete and Mike McConville and believe me these guys practice hard. Continually tweaking the programming and getting the planes flying the way they want them. Also their set-ups are pretty close even if their planes are different. TOC level pilots are a breed unto them selfs, any of the 21 could win on any given day.
