Had the the same issue with my VirtualFly TQ6 but resolved it with the purchase of FSUIPC. I use that to assign and calibrate the levers and all is golden now :-)

PS. using FSUIPC the process is analog just like the real thing.
I didn't like it at first but am liking it more and more all the time. Somehow I have mine spread across three monitors in full screen mode but am using it in VR mode now
