Slowly getting back to the Vampire after some family stuff.
Decided to put the main airtanks in the sub wing LE,, behind the inlets. (they are light so I want to space further forward for anything heavy) I'm using a UP3 valve and have an MAP hopper as shown. Wooden plate on top of tanks will take turbine valves, pump etc. Powerbox Evolution and Rx will be on the right hand side of this area
