I did 3d printed support. Nothing fancy but it gives additional strength.
I don't need a extension, I even limited especially the forward throw, as well as the rest, to mimic the F-14 stick in game. I run kind of strong forces, which work out well, hard dogfight though will bring the rhino into thermal scale down. Throws off a little muscle memory but that is mostly lost in the moment. For warbirds and Helos a extension might be something to consider, but I don't miss one. Pretty happy as it is.
