Griffon 2000TDX - 1/10 scale
The inner wall of the lift duct is made from a sheet of 0.4mm plywood,
with the grain of the outer faces running along the longer dimension.
Gently roll the duct wall and fit in place. Mark the overlap and
remove the duct wall. Glue the duct joint along the overlap line.
When the glue is dry, fit in place and then fix with glue.
A 90mm by 25mm rectangular slot must be cut in each side, 25mm from
the top edge of the duct. Use balsa sheet to make a rectangular tube
to join the duct slots to the craft outer wall. This will allow air
to flow into the skirt.
Fit the motor to a 25mm wide piece of 1.6mm plywood. Position face down
above the duct and cut to length. Glue in place. It is important that
the propellor does not contact the duct.
