The lower wing mounting system is now installed and a wing panel seems to be reasonably okay on it. It will need some tweaking over time, but I can move the mounts with a simple 1/4-in drill bit. It really would be nicer if the ailerons folded flat (my fault, not the drawings)...
This is how the lower mount looks with a wing panel installed in the trailer.
The lower wing panel is well secured by three Velcro straps and is constrained by the cross-braces for the upper wing.
The lower mount bar has a long end for wrapping the strap around. I made the upper and lower beams interchangeable, hence the extra hole visible.
To-do's before the first flight are now:
install lower wing mounts into trailer- finish weld the upper rail to the vertical supports
- finish weld all the trailer joints
- take all of Goat for its first trip around the neighborhood
- do a weight & balance
- do a very thorough pre-flight check
- acquire radios (need 1x in car, 1x airborne)
Deferred:
- wing root kiss seal
- leather patch on wing tips where they rub the ground
- leather patch guides for elevator control lines
- trim color paint
- main strut fairings
- jury strut fairings
- emergency parachute
- drogue chute
- variometer
