RE: Gen4 102 questions
Rick,
As for the balance, leave the batteries right at the end. Place them loosely in the fuse until you achieve the proper CG. I can not tell you where the will end up, you have about 12-14oz of batteries, way heavier than what I had in the manual!
Now on the tail gear subject, the rod you see in the 101, is the rod that goes through the hinges, has nothing to do with the tail gear. I haven't constrained the rod just yet. Assembly is very simple, hook up the spring to the hook and perhaps pass it through the ball link at the bottom of rudder. Take a look at the 102 manual, instead of rod you have a spring. I am assumming that's how they had it in mind! I will look on the 101.
Thanks,
Reza
