Flap horn set up.

A 4-40 screw through the flap with a washer under the head
and an elastic stop nut holding the screw on the flap. Two
DU-BRO 3/32 E/Z Adjust horn brackets for the bellcrank
and elevator pushrods. I've used this style with great success
on R/C pattern planes but this is the first for a double on a
u/c plane. Anyone else tried it?
