I am setting up a pattern biplane with my 12Z and a 6208SB receiver. It has 4 aileron servos, 1 elevator servo, 1 rudder servo and an ESC. In reading the Rx specs I noticed that channels 1 through 6 are high speed. (I usually run the Rx at high speed) Do I need to put the 4 aileron servos on SBus and leave the other three channels as 1, 2 and 3. Basically what is the best way to do this while keeping high speed and minimal channel delays? (Servos are all Futaba HV SBus2 type)

Thanks,
