Trust pipe installation
Drill 2 holes 3mm intone flange of the
aluminium brackets to mount to the wood
board and 1 hole 3mm into the other
flange to mount against the carbon entry
cone. Cut the edge of one flange as seen
on the photos.
Trial assembly everything and mark the
end of the funnel and the hole positions to
the wood construction. Use a sharp and
red glowing 3mm rod to drill (resp. “burn”)
the holes on the outer side of the fuselage.
Use 3mm screws with stop nuts for the
outside brackets. For the inside brackets
you get along with sheet metal screws.
Mount the brackets with M3 bolts, stop
nuts and sheet metal screws to the wood
boards and to the carbon entry cones of
the inserted thrust tubes.
