Very nice pictorial!
Curious; how do you use a 6-32 screw in a 4-40 hole?
I'm starting on a BH P-47 and my ailerons were already hinged and pinned as you say your T-28 was. But my T-28 control surfaces were not prehinged and came with dry CA type hinges stuck in the slots. However the control rods for the elevator were shiny new while the ones in my P-47 are covered in fairly heavy rust and will have to be replaced. (just noticed this last night)
But overall I'm impressed with the two BH planes construction. I know I haven't put anything so complex together and have it anywhere near as nice. The factory doing this clearly has the process refined.
Regards,
Clay

Thanks, Clay for pointing out the error. I will try to fix it. (fixed now) The P-47 looks nice, but I have WAY too many planes now!
The early T-28's had plastic hinges with steel hinge pins and were epoxied in at the factory, and pinned. (messy glue job, though) The later models had the CA type hinges and were not glued. Either way seems to work fine.

balsa, I am glad the hinges are not glued in. I almost always find that the hinges aren't right on line to center the moving surface against the fixed surface, eg the aileron is not centered on the wing...it will be too high or too low, and inconsistent from one hinge to the next one. I always have to reslot one or two on most surfaces. That was true on this plane too, at least mine. So it works for me that it is not glued. I'd really be in a jam if they were glued in already. AND...great job on your photo essay for the build!!! Very well done. Jon

Jon,
Yeah, I know what you mean about the need to re-slot the hinges. I've had to do that on a couple of planes that I put together recently.
Thanks for the reply!
