I did fly for two seasons with the stab just bolted on. No need to worry of it falling off or comeing loose. What I did find was that the fuse in that area suffered from small stress cracks, so I glued mine on. I glued just the front and back of the block than bolts down on the stab, just in case I ever had to cut it out to replace it. Plenty strong with the bolts and just the ends glued.

The trailing edge of the wing is 7/16 thick, if you bevel it, it will still be 7/16 at center where the hing mounts. If your concerned about removing stock from the trailing edge of the wing, then, after peeling the coating back, just add a piece of tristock to the trailing edges. Instant bevels and perhaps straighter than the results of sanding or cutting. Good luck. Joe
