It is recommended to use 5052-0 AL because it is easily flared and bends with simple tools. The 3/16 OD lines which are .132" ID work well with the -3 fittings available from many sources. Where flex is required, I used -3 stainless steel braided teflon lines and Super Jem fittings from the Industrial line of Aeroquip catalog JA316. I went through the wing close out web with -3 bulkhead fittings. It's been operating without any problems for three years. If we have room I will try to get some pictures of the installation in a future issue of the LNN. I'm glad to see some discussion on this issue. There have been many incidents of Lancairs departing the runway due to brake failures, including the Dream Catcher many years ago. Most of these incidents are not showing up on the GOV accident list. There is no redundant system (a sterable nose wheel) for us to fall back on other than maybe having landed on a real long runway with favorable winds when either the left or right brake failed. Failure of one brake makes the other just about useless. A little extra $$ and time spent on your brakes is a good investment considering new blades for your prop and a precautionalry engine tear down could cost $10,000 or more or less. I estimate that I added $150-$200 to the cost of my Lancair by tossing the Nylaflow system and going with aircraft quality or better material. JimFrantz Lancair Network News
