3.9" Avionics Bay

3.9" bay is 12" long for mounting of altimeters, timers, or transmitters.  Stepped aircraft plywood endcaps minimize the chance of ejection gas leakage into the bay.  Now comes with improved screw type arming switch.

4" length of airframe provides the perfect place to mount the altimeter arming switch.  Comes complete with hardware and detailed instructions.  Includes arming decal for the switch position.
