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

ADAHRS Mounting To new Location

 May 14 2021, Update:  I had to move the ADAHRS unit to a new location because testing revealed that there was magnetic interference in the area under the pilot's seat due to the proximity of the installed Auto Pilot servos.  The ADAHRS is now installed aft of the baggage compartment.

December 26 2020, I have a Dynon system and so a Adahrs which must be installed in a magnetic free area.  It must also be oriented in a forward facing configuration and most difficult, must be installed in a level plane fore/aft and laterally in the fuselage when aircraft in level attitude.  I chose to install under the pilots seat for reasons of easy access to reset the level attitude if required.  I had to build up a triangular wood ramp for the Adahrs unit to mount onto as the floor is at a odd angle fore/aft.  This so it would be level when in a level flight attitude.  I then made a aluminum plate to bond to the  wood base  The Adahrs unit will screw onto this using Nylon or Stainless screws and nuts.  I built up the wood base to a level line matching the longerons and then bonded the wood to the floor.  If it is out of level in either direction I can shim the Adahrs unit to make level after seeing what results I get in flight.
