I am always amazed by the flight envelope of this jet. It can fly as slow or slower than any Freewing jet I own, does bat turns, if it stalls I didn't even notice! Seriously, why stall it? You can bring it to a stop in high alpha and fly right out. It goes where it is pointed and does great 4 point rolls, KE, the works. Only fault IMHO is it is draggy and eats batteries pretty quick, it's no glider. Of course it is on the "hard to see" side, I use a gyro and think it helps to lock it in to any flight attitude. Oh, it is great in high winds and is truly great in a crosswind, it will land as slow as you dare, I would choose it for the shortest runways. Just looking at it it doesn't make sense, but there you are.

How is it without the gyro? I have thought about one, but that is just one more thing to go wrong....

I just glued the rear fuselage on mine and have a bit of an issue. I used BSI foam-cure, but did not realize that it bubbles a bit as it cures. Given the large surface area being glued, it pushed the two parts apart as the glue cured. I have a gap of about 1.2mm at the top and .8mm at the bottom. It was out enough that it cause the holes for the rudder mount screws to be mis-aligned by about 1/8 th inch.
Did anybody else run into this before? Did it create trim issues?
I would normally just run with it , but I am doing a turbine conversion, so the stakes are higher. A new fuselage is $100 plus a couple days of work lost.
I am not worried about the strength of the joint, but the mis-alignment of the tail assembly creating a control problem.
Any thoughts?
