With the delivery of a number of outstanding parts I was able to complete the wing locker and servo operating arm installs.

Now I have the fittings for the wing lockers I can finally finish off a long overdue job.
The weather-proofing washer is put over the lock barrel and the unit is inserted into the pre-drilled hole…
and locked into position with a nut.
The locking bar mechanism is fitted onto the lock barrel and held in place with a screw and shake proof washer.
The final part of the install is running a rubber seal around the inside edge of the wing locker to make it watertight. The same process is carried out for the starboard wing locker.
The wings are now complete!
Another item I’ve been waiting for is the servo operating arms so I could finish the servo install.
The roll servo is connected to the aileron operating rod with a clamp.
attached to the servo arm. The control stick and servo arm are centralised and the clamp position is marked so it can be riveted in place.
The only way you can get the aileron control rod out to is by dismantling a lot of the fittings that hold the control sticks
The clamp has two pre-drilled holes holes either side of the clamp that are used as a guide for the rivets. The first hole is drilled and cleco’d in position to ensure it doesn’t moved when drilling the other side.
Two 3.2mm rivets are used to further secure the clamp before refitting.
The pitch servo rod is a lot simpler to fit. Two AN3 nuts and bolts secure the rod in place and the final adjustment is made once the aircraft is rigged.
The roll servo and control arms completed.
Final job for today is to start installing the pressure system pipework for the pitot, AOA and static fittings
