Hello Gavin,
I reloaded the plane and tried but it's the same! So I had the right model modified!
However, as you had specified that the clickable areas were very small on the controller on the right, I "explored" the surfaces around the power levers !! And there, I found small areas on the base of the levers, but which are not active on the red balls! (see my image - in yellow) It's a shame !!!

So I put my modified plane back in place!
And if I understand correctly, it is not possible to enlarge these clickable areas!
But nevertheless, thank you for this excellent job of adapting to FSX!
Have a good day.
