Turnbuckle safety clips and starting Emp fairing

 Used this tensiometer to set the cable tension to 45 pounds.


Then installed the safety locking clips on each end of both turnbuckles.  Very important to ensure these are installed per the KAI's!



Then I got started on the work required to fit and install the emp fairing.



Pilot holes are drilled in the inside corners.


Brought these parts back to the house to work on them at home tomorrow.

Flight Controls Part 12

Installed the flaperon push pull tubes to the aft bell cranks.  Pretty easy due to good access. 


Then attached the fwd end to the flaperon mixer.

Don't forget the washers!

Assembled the flap motor mounting bracket.


And mounted the flap motor.  You can use a 9v battery to run the flap motor in and out.

Flight Controls part 10

Dropped back to install the nuts and washers on the bolts that I have installed so far on the flight controls.

The control sticks get castle nuts and cotter pins where they connect to the control column fork.  I guess they could have used regular nylon locknuts here because the bolt and bushing do not rotate.  I don't know why they went this route but I don't ask questions.

The aileron rod end at the control stick gets a nylon locknut and washer because the bolt does not rotate when torqued down.

The elevator control cable attach points get castle nuts and cotter pins because these are only finger tight so the spade end of the cable can freely pivot on the bolt in between the steel forks.

Bottom cable.

The inboard aileron control pushrod ends get nylon locknuts on the studs because the studs do not rotate after torquing.

Side shot to check that there are enough threads sticking out past the locknut.

The carnage to get all of these fasteners installed.  The DNA left on this airplane will definitely prove that I built it.
