Thanks Mitch.

Yea, I was considering a narrow (1" probably) strip of cloth and epoxy or simply CA. I don't think weight in this area will be an issue in either of our builds since you're using a 4 stroke and I might use a tuned pipe. I noticed that you placed your empennage servos in the rear. This will presumably help to offset the 4 stroke weight.

I'm not sure if you had in mind placing your battery above the landing gear under the tank but I would imagine that might be option if necessary. Somehow I suspect that yours might end up just aft of F2 for CG purposes and mine probably too. In any case, space is not an issue.

I don't recall but I believe Jim doesn't make a point about the stab junction. Between thick fuse sides, triangle stock and fillets I'm not too concerned about the strength of the stab junction once glued in place. I don't plan to install the bottom block until the stab is in place allowing the glue joint to be strengthened. One thing I did consider was to make an extension to the fin bottom so that it would notch into the top block but I ended up not doing it.

David.
