Here is an interesting observation. Every time I find a topic on RCU about a controversial topic with multiple opinions I find this result. There are always those who use things for years without failure.

Examples - stock fuel tanks, PPM Rx in gassers, CA hinges in gassers, Plastic spinners on gasssers and glow engines, Fuel valves on gassers. Mods such as pinning and fiberglassing the firewall mounting box when using gas engines.

For me, this is what I experienced within the last five years. Stock tanks failed twice and now I don't use anything but a Dubro, Sullivan or Hayes tank and have never had a failure since. CA hinges failed on my Pitts and now I use Kletts Flexpoints or most recently Robart hinge points. Too early to tell how well these will work, but they sure seem to make sense if you look closely at the design vs CA hinges, and I have never read where someone had a failure using them. Fuel valve on my DA-50 developed an air leak - think the seal failed due to vibration. Now using a fuel dot so this won't happen again. I have never used PPM Rx on a gasser because I just didn't want to have to learn this lesson the hard way. I used a PCM after testing with PPM and making sure there was no interference. I also didn't have to learn the lesson about plastic spinners or having firewalls come lose because I did the proper things to ensure that I wouldn't have a problem in these areas, so maybe I'm ahead of the game on these issue.

To each his own I guess, but it amazes me how many times I hear about people using products with known failure experiences and then they change after they experience a failure of a product. I know I've done it. We all have to learn at our own pace I guess. I know nothing is ever 100%, but some things sure make more sense than others.
