RE: F3A Special Pattern Radios
The Kraft Signatures and the Prolines had the cross trims in better places. They were at the upper right and left corners so when you wanted to trim the elevator you just took your thumb off the throttle and it was right there. Cross trims in the center of the TX is a bit of a oddity. I have 2 used Kraft Signatures and I would say keep it NIB. If it is used 1 time it is not NIB; you probably have the only one left.
