This is a short section but one you want to take your time on. Over two days I was able to get the flap torque arms and the motor (flap actuator) installed. *note: The jig for this first step where you match drill the torque arms through the crank comes in the wing kit. If you don't have that, it's $15 from the Van's store ☺� Once we got it lined up and measured it four or fives times (it's a little confusing as they have you line up the inside of the flange in the middle to the outside flange of the end. However, we got them both lined up and then drilled them out. After that you upsize them to #12 to fit the an3 bolts. It was a little bit of trouble to drill through both holes so I found using a long #30 to make sure the holes are lined up perpendicular to the ground while I drilled made it easier to make sure I was in the second hole. The holes should center themselves but I am sure some people will elect to use the drill press here. I did not, and found no issues just using my hand drill and taking my time. I also primed the insides using spray cans. I started by running a long drill bit with some scotch bright pads which helped clean up the insides of the tubes. I then repeated with some acetone and finally sent through some acetone soaked paper towels to clean out any residue left behind. Then I just taped off the edges and primed them with the SEM self-etching primer. After that is complete you install it into the plane, torque the bolts and apply the torque seal (except for one bolt at the top that needs to turn freely and you use a nut castle and clevis pin). There is one section where you have to drill a hole in the flap actuator which will allow you to attach safety wire which is part of a service bulletin for older RV's. This seemed like it would be hard but actually it was quite simple. Now I just need to get my safety wire back from my buddy and install it to be done with section 34. Onto the sub panel!
