So far, just within AH2
I was pondering...I have the very same problem with MS Flight Sim 2004 where I simply cant use it for a similar reason, it just never gives full power (50% or a tad less). Only in that program, there is no means to recalibrate other than the Windows Settings -> Game Controllers. Your application at least gives you a means to correct it.
I'm going to surf Saitek's site too.
