Assembling the airbrakes
The airbrake assembly has two main components: the airbrake and the airbrake top.
 First give the holes in the airbrakes a very light file to remove the paint.
 Then take the airbrake tops and use a tap to clean the epoxy out of the threads. Clean
around the base of the bolt with a knife to remove the extra epoxy.
 Now thread the supplied brass spacers onto the bolts in the airbrake tops. The threaded
part of the spacer should be aligned with the top of the bolt and the unthreaded part
against the plastic. Tighten them slightly with pliers, but do not overtighten the spacers
or else they will break off.
 There is a slightly shorter bolt at one end, which lines up with the lower side of the
airbrake. There must be free movement of the brake on the spacers. Place the springs
over the spacers and be sure that the short one goes on the short bolt. There are special
washers that go on top which have a larger area to hold the spring in place. Use the
4mm nuts and blue Loctite 243 to secure them into place. Tighten the nuts until they stop
on the spacers; do not overtighten as you may strip the bolt from the plastic.
 Place the two long spacers on the second pin from the left and the second pin from the
right. Be sure to secure them with Loctite and tighten them with pliers.
 Now place the angle brackets over the spacers and be sure they slide reasonably well.
Position them about 5 mm from the base of the spacer as shown in the photo. Drill two
3.5mm holes and secure the bracket with rivets (those which have a larger head). Mark
the nuts with red paint.
