Saitek Throttle and Flightfactor A320 problem

[737Andi 6]

Hello,

can anyone please tell me how I can use one lever of my saitek throttle to control both thrust levers of the A320 at the same time?

This is working fine on other 2 engine aircrafts like the ZIBO 737 or the Flightfactor A350. For these aircrafts I have assigned the command "throttle" to the single saitek lever, which is then moving both levers in the simulated aircraft. However the exactly same setting is not moving any thrust lever inside the FFA320.

Here I have to assign two saitek throttle levers to "Throttle 1" and "Throttle 2" to solve the problem.

This is however very annyoing because then I cant assign the third saitek throttle lever to my speedbrake.

Does anyone have a solution for me?

Thank you very much!

Best regards Andreas
