I thought you had the 1 ton? Don't need the extra tongue weight?
Well, still consider having the spar and motor mount with the same structure

I would highly recommend the Gemini to anyone comfortable flying a plane with ailerons. It is quite docile except in gusty winds when it will tend to jump around a bit. I did pick up a new motor for it this weekend. Its a 450 class from Common Sense RC. With the 10x5E prop I have on it, it's rated at 44oz thrust.

the wing "airfoil" is really, REALLY sad. It nearly looks as though the main wing would fly better backwards. You need to blunt the nose and sharpen the trailing edge. Sharpening the trailing edge while you do aileron construction is a good idea, but don't forget about that sharp leading edge, you will get really poor off-design performance the way it is now.

Actually, I'm planning on using a line of epoxy at the bottom of the groove to bond the CF rod, then a 50/50 or 25/75 mix of epoxy/microbeads to fill in the groove around the CF rod and make a smooth surface.
As far as the wing goes, yeah it's a horrid airfoil. I can't imagine it would have changed the mold price significantly to make it at least semi-symmetric. I intend to round off the bottom of the leading edge and sand it down. I'm thinking I am going to make a 1 1/2" extension for the back of each wing that tapers down from 1/2" to 1/4-1/8" and glue it to the trailing edge. The ailerons would be cut out of that extension.

Thanks for the recipe. My wife will tell you I never measure anything, I just mix till it looks right. However, I have no idea what looks right here so the hint is good. I am assuming that at that ratio there is not much bonding strength and it mainly works as a filler?
