Thanks Steve... the cap is 11/16 of an inch in diameter which represents 2.75" inches full scale... I think the full scale is closer to 3"; but the PL259 looks close enough.
And my mind continues to wonder... I was thinking about animating the control stick in the cockpit by using some pull pull cable out the side of the fuse and along the forward strut, around a working pulley and connected to the servos in the wing... for safety, adding a lite weight spring inline on the cable inside the wing to protect the servos in case of any binding that may occur... but that all depends on how much weight I have added so far.
