Hi Dave,
We have a mono airplane & bought the glider wings to be able to switch between
airplane & motorglider. We have 500 hours on the airplane but haven't done
much
work on the glider wings.
We started Mod 78 and completed laying up the ropes (2 people can do 1 spar in
a long day). Be sure to use Bud Yerly's notes in addition to the instructions
---From Europa. We had to redo the first spar because the orientation of the
mold
was not clear & we had the bump up instead of down. Clearance is very tight.
After that, at Bud's suggestion, we checked clearances using the intensifier
board
as a template and found that the new wing spar will not fit - it contacts
the flap actuator rod. This is only an issue for the mono airplane
configuration
(flaps actuated with gear retraction). Apparently the factory tested the
mod on a pure mono glider and on a tri-gear airplane but not on a mono airplane.
Because we (like you) don't want to screw up the wonderful flying
characteristics
of our Europa, and we have the added issue of re-engineering the flap actuator
rod, we have stopped work on Mod 78 and are thinking of selling the glider
wings.
