Well then that’s a whole different thing… you didn’t say you were an expert…… My gas setup is as follows:
DA50, Slimline Pitts style muffler (non-smoke).
Futaba standard servo for throttle (S3003) & choke (S3004).
Futaba 3010 servos on Ailerons.
Futaba 3305 servos on Elevator.
Hitec 645 on Ruder.
One Hitec Rx.
NiCD Receiver battery, 1500 mAh (2/3 sub C size) 6-volts.
NiMH Ignition battery, 1650mAh (AA size) 4.8 volts.
Heavy Duty switches for ignition & radio system.
Dave Brown 3.5” spinner.
Pro Zinger 22x6 prop.
Dubro large servo horns on all servos.
Hanger 9 Titanium Pro-Links turnbuckles on AL & EL.
Dubro Pull-Pull cables for RD.
Dubro safety lock Kwik-Links on all push rod & pull-pull connections.
Hanger 9 heavy-duty control horns on AL, EL & RD.
Sullivan tail wheel assembly.

Wheels, landing gear and the rest are all stock. I did not use the stock linkages or control horns but what is listed above was used. I moved that Battery and Rx as far back as I can under the hatch. I use a Futaba 9C so I did not need an expander, all the servos go to one of the channels on the radio.
Channel 1, AL right
Channel 2, EL right
Channel 3, Throttle
Channel 4, RD
Channel 5, Choke
Channel 6, AL left
Channel 7, Battery
Channel 8, EL left.
