Instead of having a two servos for one aileron connected with a y, each servo can be plugged directly into a RX. Imagine the load if you had a four servo rudder connected with 3Y's, going to the one rx, it must be better to split it across another whole system. How many amps can a switch handle. I was in a discution with Jason Kruase and he mentioned that his fury, with 4 digi's, gov, and gyro, will draw up to 5 amps. Now how about a 17 servo ultimate! It has to be up there.
