ASSEMBLY MANUAL B-25 Mitchell ARF - RC DEPOT

Section 9: Retract Valve and HardwareAll pushrod hardware and mounting plates are suppliedby the modeler. Step 1You will need to fabricate a plywood plate to mount theservo and the retract valve on. We made our mount fromlightweight plywood and a small piece of triangle stock. Step 2We use a plastic 2-56 clevis to attach a 2-56 pushrod tothe retract valve and then make a “Z” bend on the otherend of the pushrod where it attaches to the servo arm. Thepushrod should be placed on the servo arm a distanceof approximately 1/2-inch (13mm) out from center of theservo arm.Note: Use travel volume on your radioto allow a maximum 1/4-inch (6mm)of travel on the pushrod. Be sure tonot over-throw the pushrod. Step 3Mount the air fill valve on the fuselage so that youhave easy access to make the connection. The fillervalve will be less noticeable if mounted towards thebottom of the fuselage. We chose to mount the valvejust forward of the leading edge of the wing next to thesteering servo access hatch.52
