Default RE: Large Skymaster Hawk build

I just wanted to mention a problem I had with mounting the stabilizer bearing block. I noticed the sides of the fuselage were bulging out close to the bearing block. A little investigation discovered the aluminum bearing support was digging into the fuz. i didn't notice this problem when I first attached the stab because there was no compression of the glass, It may have had a small amount of glue supporting it and the constant bolting/unbolting must have dislodged it. When I checked the structure I made certain there was a 1/4 inch ply plate bonded into the structure at this position. The problem is that the ply hasn't been glued flush with the fuz. The forward holes are fine but when I opened up the rear mounting holes I found there to be a 6mm gap between the top of the ply and the start of the glass fuz. To solve this I used 3 large penny washers ontop of the ply so the stab has something solid to bed down onto. While I was working on the stab I carefully checked the geometry of the servos and linkage with a laser and finally bolted the 8711's down.

The touching up on the paintwork was done by SM, it's a bit messy yet to sort it out......just thought I'd mention it in case you thought I was getting messy.

Cheers, Alex
