Rigging Flaps - 3 hours (178 Total)

I spent a few hours trying to rig my flaps to have the correct amount of droop to no avail.

During the process I noticed that I had bolted the teleflex retainer in the wrong hole in the left wing. There are two holes about an inch apart in the compression tube. The manual clearly states which hole to use within the text but doesn't reference it in the exploded parts diagrams. Luckily the holes were pre-drilled to the correct size for the bolt (I would have never been able to get a drill inside the zippered portal to drill out the hole). With considerable effort I was able to unbolted the teleflex retainer and move it to the correct hole.

Even with the teleflex retainers in the correct position, I still wasn't able to adjust the flaps to the correct droop. I adjusted the following components in many combinations...
  • Female Rod End - While maintaining min 10 threads
  • Teleflex Retainer - I've rotated this to point forward and aft but the change it makes is too great. I verified that it is mounted in the forward hole of the Flap Compression tube.
  • Insert Nut - While maintaining min 10 threads. I also tried removing the Insert Nut and using a lock nut but the change it makes is too great.
  • Flap Lever Teleflex Cable - I've adjusted how far the shackle bolts onto the threaded end of the cable.
  • Unihorn - I verified that I'm using the correct hole (there is only one hole left after the unihorn was cut down to size) and it is oriented in the same manner as the assembly drawing.

I will contact Rans and ask for their advice.
