Yup, in an earlier posting, one of my club members has a model with FOUR servos on the rudder alone. That model uses one of those powerboxes to handle the maize of servo connectors, what with rudder, elevators, ailerons, and flaps.
I think he has more in servos in that model than my $1000 Extra 330's total cost.
