Si-F3a

Hi I recently bought this combo to replace a 14mz and have a couple of questions re the setups for non futaba digital servos in a flightline spitfire 1600. In order to us the sbus output as I done have enough output on the receiver for
1 rudder servo
1 Throttle servo
1 Elevator servo
2 aileron servos
2 flap servos
2 gear servos
+ 1 connection for 3 led lights onboard
Makes 10 connections.
Can I use 2 ail, 1 rudder, 1 Throttle, 1 Elevator on their regular ports and then do I need to use an extension lead with built in decoder for the remainder?

Not sure what is the right or best way to set this up so looking for the best way forward.
