Thanks all. Waiting for harnesses to dry so moved ahead a bit. Part J15² installed. Should have the fuselage buttoned up shortly. When I got home I did another wing/fuselage test fit and added a bit of dihedral. It now looks like no filler will be needed after all
Belts are glued in place, just waiting for the joystick handle to dry and I can put the cockpit together. A big shout-out to Terry Airframes
for the heads up about the seat being too far forward
Once glued to a fuselage half I'll be caught up on the other build and I'll start painting the engines
