Thank you.
The cub is a 48". The 1/2 " is in the book for high rate and 3/8" for low.
When I did it first it seemed very little so I just wanted to make sure I am measuring it correctly.

Thank you for the detailed explanation - Yes I needed it (I am true noobie ).
Yes it is better somebody to tell you from his experience instead of finding out the hard way.

I am almost ready. All servos and throws are adjusted as good as I can.
Only the balancing remains... )
