are positioned at 35mm, 126mm and 180mm back from the front edge with the nose
cylinder attached to the front pair. It may be necessary to trim the rear hinge to clear
the nose wheel steering servo which sits in the door opening in with the leg in the down
position. This depends on the depth of servo case on your servo choice. The curved
nature of the nose door may require some additional bracing to maintain the shape. We
used some scrap 3mm hard balsa as shown. The supplied hinge rod should remain
straight even though the nose door area is heavily curved. The front and rear hinge
tubes will touch the fuselage skin, the centre tube will require supporting with some
scrap balsa. By design the Hawk doors must move away from the fuselage immediately
they start opening to guarantee smooth operation and clearance while opening.
Sanding a small radius on the inside edge of all doors will reduce the chance of them
catching on the fuselage surface.
The recommended Robart air cylinders can be mounted near vertical in the height of the
