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

Engine Silicone Baffling and Auto Pilot Servo mounting

 March 7 2021

A large part of my time this month was spent fabricating the Silicone seal baffle around the top of the engine.  I set up a system of sliding wooden pieces to identify the height from metal baffle to inside surface of the cowling.  Then I was able to determine the width of silicone to use.  The standard 3 inch stuff worked out to fit well.  I decided I wanted all silicone to be removable and so installed on #6 nuts and bolts with a aluminum back plate.  This also allowed me to use pieces with fewer separations as I did not have to account for each separation in the aluminum baffling material below the silicone.




I began building a two brackets for the autopilot servos, the roll unit going under the passenger seat and the pitch servo insider the center console.  A lot of test fitting was required and the aileron and elevator push pull tubes were disconnected and reconnected many times to find the right fit.



The position of the A-pilot units ended up to be too close to the ADAHRS unit with a magnetometer inside it so I made a new bracket for the ADAHRS and positioned it in the rear just behind the baggage compartment.
