RE: Servo Rules
Many guys these days have been installing the 3102 Futaba servos, they only have 2 lugs per servo. But what is smart, is they guys are using a block of wood (spacer) between the two servos... and some two-sided tape to make the two servos seem as one. I've only seen this on V-tails, but you could do the same in Q40 for rudder and elevator. I personally think that is plenty strong enough when install correctly.
