| One of the key rigging measurements is the wing sweep - or lack thereof.
The RV 7 wings are completely straight - or should be.
We stretched a reference line across the floor and then use a plumb bob to align the outmost
and inboard leading edges. Generally both wings were pretty good - about 1/4" difference along the length,
but both were slight swept forward. | 
|
| Part of the reason for the problem was the first rivet above the rear spar attach point. The AN470 (domed head) rivet interferes with the wing spar. | 
|
| The solution? Either remove material off the spar or remove and replace the rivet with a AN426 (counter sunk) rivet. I decided to go for the later. | 
|
| Even with the rivet modification, a little filing on the spar was needed to assist with the various rigging requirements and mounting processes. | 
|
| The rest of the afternoon was spent with frustrating problems.
Everywhere we looked / reached for something it didn't work or required something else.
All a bit depressing but on the positive side I did manage to finally get the IT / database back up and running. The log entries are a little out of date, but I'll catchup as soon as I can. | |
