RE: Brent Good Custom Airframes 50cc yak kit
Been getting a little done on the instructions. Just thought I would throw in a post and bring this thing back up. Here is a look at the elevator.
Next I use a cone shaped grinding stone in my drill press to make the reliefe for the hinge knuckle. Glue the beveld stab and elevator peices in place. Take extra time to get them centered on the surfaces. You also need to shorten the peice that will be glued to the stab. When every thing is glued in place there should be a 1/8" gap between the stab and the counter balance of the elevator. I glue the beveled peices on with tightbond wood glue. Gorilla glue will expand into the holes that you have drilled for the hinges and can cause a bit to move off center when you redrill the holes. Use plenty of tape to securly hold the beveled peices in place. Once dry sand them flush with the sheeting. Drill through the holed into the foam and you are done. I get a little over 60 degrees deflection by doing it this way and no hinge gap.
