ok...  after my last post I decided to spend a couple of hours going over the FSUIPC manual.  First I updated FSUIPC and the manual... In the updated manual Pete states that calibrating flaps via FSUIPC is (sic) more trouble than it's worth.  So I disabled flap calibration in FSUIPC and the flaps in all of my A/C work fine; including the CS707.  Duh!!!

So Windplayer and Markoz thanks for ur time and comments.
