This is the Vision prototype designed/built by Steve Rahm in USA. and still being supported by Pro Composites Ltd. in USA. The aircraft is a 2 seat side by side, scratch built from a series of manuals. Built entirely of fiberglass and carbon cloth material the builder needs to know or learn some of the easy basics of composite construction. Building began Feb. 1998 in my spare time with 7 years where no building was possible. Building Hours at February 28, 2022: 4248.--------------------------------------------------------------------------------------------------------------------------------Some short videos of flights are at: https://www.youtube.com/channel/UCfxJXIwvmfNlNF3gwplFw7Q

Mechanical fuel pump shroud construction

 January 15 2025

As mentioned earlier I have had issues with my fuel pressure getting as low as .5 lbs.  I have already made stainless steel exhaust pipe deflectors and wrapped heat protective wrap around my fuel lines.  After still having issues I then made a ram air scoop to increase the air volume to my oil cooler.  This second update made a world of difference and reduced my engine temperature by 24 degrees fahrenheit.  The issue was that my mechanical fuel pump would get too hot and the slow moving fuel would then vaporize at times of extended taxiing on warm days.  The oil cooler scoop has made this almost a non event now.  Because I would like to be able to operate in warmer climates such as Arizona I wanted to build one more fuel coolant solution into the system.  I have made a custom built shroud to cover the mechanical fuel pump out of carbon fiber and fiberglass.



The left magneto had to be removed to install the fuel pump shroud. The cap is held in place with two screws into the lower piece.
