I fly a six servo giant scale decahtlon with a futaba 6exa and don't have any real complaints. Model naming would have been nice ( the new ones now have this) and not having a mix for my dual elevators was a bit of a drag, but I would have had to by a 9CAF /CAP to get that mix. So instead of spending $499 I bought a $10 dollar reversing y-harnesses.
