Thank you for taking the patience of answering in detail. As it happens I am also from downunder.
I believe I have already followed the procedure you have outlined.
The hardware controls are the TWCS Throttle and the T16000M FCS
(Note that the T16000M has a little Lever Throttle at the base of the Yoke which works perfectly).
I still have a persistent problem which inhibits me from taking off using the Throttle on the TWCS throttle handle however.
I am using Windows 7 Premium, XP11 Ver 11.34 64 bit, no pedals, no special yokes. Also a registered version of X-Camera whereby I assigned about 20 camera views and controls using both hardware components.
The Lever Throttle on the T16000M could be part of the problem. Because it rubs under my arm when I am operating the Joystick, I use the other throttle handle on the TWCS. Never any problems on FSX or indeed XP 11. It gives me more dexterity and no unexpected fluctuations in speed). Therefore I taped down this Lever Throttle.
As of writing, all stock aircraft and a Zibo Boeing on XP11 are working fine using the Hand Throttle still with the Lever Throttle taped up. Importantly, the TWCS Throttle works fine with all of these planes too.
Of late I installed the Carenado S550 Citation and worked fine for two weeks. But all of a sudden I got a problem.
So two problems.
Cannot use the main Handle Throttle.
Persistent message in white reversed out of Magenta colour “Multiple axes assigned to Throttle”. I do not know which throttle it is referring to. And I cannot get rid of it.
I have re-installed the aircraft but with no change.
I have not as yet re-downloaded the Drivers.
I noticed from your guide that I had a couple of controls assigned to multiple buttons just for ease. I took all the controls out completely and this message still persists.
Note I cannot find an Attach instruction on this Reply Setup.
