I toyed with that before low-priced solutions like the uAvonics one came

There was an article in Kitplanes magazine several months ago about a guy
who built an elaborate blower system to give his new (certified) engine the
same ventilation it would get in flight. That way he could do the complete

Has anybody ever tried using vinylester resin to fasten a layer of
heavy-duty aluminum foil to the inside of the tank.? Then as far as the
gasoline is concerned, you'd essentially have an aluminum tank, and if you

The IDEAL tank would be polyethylene, which is what modern cars have. It's

If that's really the case, then de-ethanolized gasoline (or whatever you

The statistics on the safety record of homebuilts are somewhat misleading.
According to studies by Ron Wanttaja in Kitplanes Magazine, the safety
record is much worse during the first few hours of flight. After that it
decreases and eventually the safety record is similar to that of certified
