I wasn't referring to any one person. I'd suggest most flying AMA at 11 lbs and ~4300 mah packs have realized the benefits of flying electric and are willing to push to the ragged edge (4300 is not much reserve for many flying Masters) to keep that advantage. Of course there are other reasons to fly electric.

Perhaps not mass produced (but how many pattern kits really are), but Todd Schmidt is not the only who has built a Defiant. In anycase, you asked for 1 AMA plane, and you got a list.

Bigger fuses started growing to match available horsepower (which has continually increased since the displacement limit was removed), and this was before the current KE demands in F3A.

Please reread my post - I did not state a legal 5kg F3A electric model was potentially incapable of flying the entire Masters schedule. You stated AMA power demands were less than F3A (which would suggest any F3A capable electric plane would be more than capable for Masters). I'll elaborate on my original comment. The AMA patterns may have less demand (than F3A) for specific maneuvers, but the mah used for each pattern ends up pretty close, since the more demanding F3A patterns are shorter. Most Masters schedules I've flown use slightly more mah than a P, and slightly less than an F - again, it depends on which exact schedules.
