OK, if we want to get picky, lets recall first that the major body parts are molded/vacuumed FRP, not Aeropoxy/Fiberglass components. So while the Tg for Aeropoxy is indeed just over 190F, it is not
Hi Fred, That was the "second" red one, after the first melted! Prepreg material is no different in temps of having a Tg, Lancair kits these days are baked. Another interesting point to consider is t
Hey Ron, It was a stock 914 you bought, not a Predator variant right? I was flying in your neighborhood last week with an OAT of -15C at 8000 msl. As for top altitudes, I do not recall seeing a publi
Internal combustion engines are very sensitive to exhaust gas pressure. In operation, the cylinders put out large pulses of pressure and want to clear the contents of the exhausting cylinder as quick
Hi Guys, Its been two years since preheaters have been discussed here. Paul, Are you still happy with the Reiff? Anybody else happy or unhappy? Any new data on the JC Whitney variant?? Has someone fo

Hi Richard, The carb socket area should not see particularly high temperatures. The clamps are probably too tight. Of course, if the plenum pops out in flight, the engine will run very rough. Do you
The Tg for Aeropoxy is 194-196F depending on which hardener is used. see:http://pages.sbcglobal.net/ccanedy/aeropoxy_main.html The only Tg for polyester resins I could find on the web were in the ran

Hi Jeff, Included in my exhaust saga was a cracked heat shield as well. When the entire exhaust system was replaced, the new shield was redesigned to prevent what were analyzed to be thermal expansio
