RE: Sterling 48
The rear cabin roof was glued on. I had to put some balsa strips along the top of the bulkheads to get some more contact area for the roof. Pins did the rest.
Tom, I removed the motor from the mount. The mount looks like it's .090 aluminum and it has some substantial holes in it. I can drill .25 or even .375 holes but not that big one in the center. The only ones that need to be accurate are the two #6 holes for the mounting screws. I'll wait for Astro Flight to send me a drawing and if I don't get it in a few days, I'll go out and buy a decent vernier and make my own using the dimensions I get from the motor. It would be great if you have two of the AF 425s in your stash. Dan
