Doing a small amount of research we learn that there are two ratings of interest when considering a material for sound control, NRC Noise Reduction Coefficient = sound absorption Cork said to be 0.7 N ...

When it comes to Europa interior airflow each aircraft is somewhat unique, so I would not write off the duct from bulkhead to sternpost for all Europa's if it doesn't work on one. I think for it to be ...

I have been reading a few article's regarding the properties of cork insulation, light weight, fire resistant, sound absorbing, and thermal insulation properties. I was wondering if others considered ...

Interesting what a computer can say about shape changes on a aircraft. The B model Piper Aztec offered optional 22 gal tip tanks of a different shape to the standard wingtip. It was said they were Ho ...

I have the Beringer complete kit but no hours using it yet. It's been on the market about 10 years many Europa owners have been using it. In the beginning there were worries expressed about it getting ...

It will vary but winter mogas has typically 10% more butane to help it start in cooler seasons, butane has 20% less energy than gasoline and evaporates easily so it doesn't age well in a vented tank. ...

Hello Chris, that was a interesting video you shared, years ago I drag raced a mildly modified '70 Ford Mustang 351C engine, I didn't have a oxygen sensor I used the time and speed to tell me how to j ...

Hello Area51, thx for sharing. I see the contoured washer's and bolts instead of pins. I tried something similar ( Rhichard Collins LAA aproved mod ) it uses nut plates on a sectioned piece of tube ...

Ahh the fabulous Baker build I have heard of her! Nice details, Paul Lipps would have approved of your vent scoops, he once wrote of scoops vs NASA scoops in Kite planes magazine. Clean looking wing j ...
