RE: GP Extra 300S - Group Winter Build
Some more pics. Photo #1 is finished elevator.
For the rudder, the main issue I had was running out of the 5/16" sq stock. The CB on the elevator used up about 12" extra and I was about 18" short given the additional requirements for the larger CB. I did not have any in the shop so I used 3/8" sq stock instead; you can see the rather beefy ribs; I planed and sanded it down to 5/16" after it was framed and glued. Again, I used 1/4 triangle stock along the hinge line of the rudder.
Photo #2 = bottom of rudder started; Photo #3 CB close up. Photo #4 finished before sheeting and Photo #5 is finished unit.
