Default RE: Composite ARF Impact - New Build for 2007

Malcolm,

Thanks for the tips regarding wing/stab incidence, I have made some build progress (if I could only quit my job, get a full-time nanny for the 5-year-old and hire some help around the house for my "honey-do" list) and have gotten the bulk of the cutting, sanding, aligning and gluing out of the way. I am working slow simply because I have limited time and I am still absorbing the manual, some other builds I have viewed online and the info I am getting here. I went with a solid, non-adjustable wing mount (glued main and pivot tubes) and am considering adjustable incidence for the tail as you have done.

I have a few questions if you don't mind me taking advantage of your Impact experience?

1.) Do you think I need reinforcing around the firewall? I used AeroPoxy and used the included firewall from the e-mounting kit, I know this is strong but I am considering gluing in the second firewall (it's the one used when mounting a hacker, to hold the rear of the motor) and some spacers between the two to really "lock" in that area. Waste of time or worth considering for the extra 4 ounces?

2.) My kit didn't come with a stab outer tube, not the tube that inserts into both stabs but the one they show in the fuse between the 2 reinforcing rings. Now it appears that they simply intend that I glue the reinforcing rings in the fuse and slide the tube through to mount the stabs (the holes are fit right for this 10mm tube), it just seems to me something needs to hold the fuse apart back here (without the outer tube in the fuse you can push the sides in a bit) and I would lke to know if you went with the outer tube as show in the manual or have the one I describe?

3.) The pull-pull setups I have seen (only 2) show a slot cut for the wire to exit the fuse, I don't want a slot and would rather use a sleeve where the wire exits the fuse (aligned as best I can so there isn't much side-to-side pressure on the wire), is this acceptable? Any concerns?

4.) Do you recommend gluing the tail wood in before gluing the hinges (after a perfect dry fit)? Seems to me gluing in the entire thing in one-shot will be harder to get good glue coverage. Any tips?

Here are some pics, nothing too far along yet, just the basics and core parts...
