B.A.E. HAWK

Main gear door installation.

The main gear doors are supplied moulded in one piece. These should be separated

into three pieces, the larger inner section is hinged using the milled phenolic hinges and

the supplied rod and tube.  The centre section will be fitted to the struts and the small

base piece notched to clear the strut, or hinged if you chose.

Operation of the inner doors requires two large bore approx 1.5” stroke air rams. These

can be bought as part of the optional Composite ARF air pack #200550 or sourced

individually. We recommend Robart 3/8” air cylinders F-RB165. These are angled and

overlap each other in the wing centre section.
The hinges need separating from the phenolic sheet and the retaining tags sanding off.

It is good practise to tack glue the hinges and tubes in position to allow easy adjustment
