Jack, just came in from finishing up the changes to my air system connectors and read your post. Glad to hear you like the jet. My setup is very close to yours. I see you needed 3/4 pound of lead in the nose. Did you melt down lead and pour it in a mould of the nose? I'm also going to look into adding a gyro. Probably my biggest worry is tracking straight on takeoff!
Tomorrow I plan on pressurizing the air system and check for leaks. I'm also going to finish hooking up the ECU and other electrical work. I still need to do something about the bird's nest of air hoses, aileron and flap servo leads in the wheel wells. I've been scratching my head over how to organize this stuff so that nothing gets hung on a wheel. I've got the BVM wing root air connector kit, but it sure looks like it would be easy to get it slightly misaligned and end up with a source of air leaks.
