How do I hook this up?? One is the brake valve the other the retract valve for my yellow aircraft FA 18 and I don't know which barb is which. I am also looking for pics on your gear setups, ie rc, battery, air valves etc.

Hey bud,

The smaller valve is for brakes, larger for gear. The single barb on the brake valve, and the center barb on your retract valve go to your air tank. Good luck,

Erik

What about the other barbs? That leaves 4 barbs I have 3 retracts each with 2 barbs an up and down I guess I need a diagram. Thanks

Does this help?

That's great thanks and the two screws are for adjusting the speed of the gear up and down correct
