I did another drop test on the modified/repaired gear and it seemed to do ok. I did two drops from 9.5 inches and 11.5 inches with no visible damage. It seemed to flex and perform ok. I haven't viewed the video in slo-mo yet as I have to get the file off my buddy's camera. I lowered the tire pressure to 13 psi--interested to see how much they compressed.

If I were to reproduce that 11.5 inch drop on a bad landing, I think the rest of the airplane would be in bad shape. There's a real possibility that a failure mode will develope with repeated use but I suspect it would be gradual rather than catastrophic. So, now I'm tempted to use it after all but would keep a close eye on it.

Thanks again everyone for all the thoughtful responses and support!

From the video, it looks like the gear compressed about 7-8 inches, 3 inches of which was the tire compression. The gear is definitely stiffer without the laminations separating.

Price of materials--$300. 100 hours of tedious labor--priceless.
