How much dihedral is enough?
I just built and am training on the PT40 with max dihedral.
It gets alot of comments at the field, but it is very easy to fly.
I thought I might build a second 'sport' wing, but have decided to move on to a complete new kit.
Re the three screws for the hatch cover, harden the holes with a little thin CA. They are working fine for me.
