In storage, a peculiar problem again has surfaced and I do not know how to remedy it. On the leading edge of the canard I’ve noticed many indentations. It’s as though a sharp edged tool was hammered down the surface. These indentations are about 6”-8” apart, 1”-2” long and about 1/8” deep. The layered expoxied fiberglass seems to have been sucked down. Don’t know how this is possible! The foam beneath this could have shrunk, making these indentations. I wrote to Ron Alexander about this. He suggested I fill the indentations with an epoxy slurry mix, sand to the adjoining surface and then place another fiberglass layer over all of this. A lot of work, but worth doing.
This question resulted in responses from the QLIST including one very civil response from Jim Masal! There was a general concern for the leading edge because that area does add to the torsional strength of the canard. Masal stated that he had never seen this symptom on plans-built canard before and that a good close-up photo of the problem area would help. It sounded to most members that the damage is likely mechanical in nature by something being forced into the leading edge of the canard. The suggestions included:
The original text of the responses will be mailed to Ted for his review and consideration. These responses are only based on the description of the problem above and may not resolve the issue. In any event, the leading edge of the canard is a very important component of the Quickie design.
