The bungee cord attachments have been modified, I didn't like the crossing cords (the "in -triangle" reinforcements are not in place yet - Avid Flyer pilots know what I'm talking about). Throttle handle is back where my left hand rests and I have replaced the level trim/balance bungee cord by my home made version of the Sonex trim system.
The fuel system has been review with a protected, while easy to reach, tank selector and replication of the fuel level alert led. The button in the hole is air purge valve for the feeder tank. When one wing tank is empty the level on the feeder tank goes down and triggers the alert on the dashboard. After switching to the other wing tank the fuel level in the feeder tank is increased by purging the air.
A fuel tap has been placed close to the firewall and an easy to inspect (and replace) filer. The tap is accessed from under the dashboard and a micro switch triggers the fuel alert when not completely open.
The exhaust system is as usual difficult to position due to the classic Avid Flyer landing gear. At full bungee extension the gear can touch the pipes so I have made an extendable mount, linked to the landing gear, that will protect both in case of a hard landing...
