Sorry I’m late to reply too, but thought I’d throw in my thoughts too:
It’s fantastic. I love the “feel” from the engine, stall, and g-force. The original foam pad was a bit thin for me, but comfortable for an hour or two. (I’m a big dude, ~250#). I ended up modding it though since I also got their Boeing seat. That made the strength a little muffled since the foam is thicker and a bit harder to feel front to back on the bottom cushion, but the overall “feel” in flight is still there. (And I had to turn up the overall strength from ~mid to almost 100%). The differentiation between the inputs (engine, flap, g-force, etc) is pretty well tweakable through the software. I’m using 1.1.4.3 with much success. The only other downer was that the simshaker software seemed to give better variable sensation within the input modes. Like I really felt the ground roll undulations and “seams in the concrete” but it also did not support all 8 pads. I’m thinking that as the HFS software improves, it should only get better.
I fly everything from ultralights to tube-liners to light GA to an occasional darkstar/F-18. I pretty much haven’t changed the settings between the aircraft types, and I’m really happy still.
@Baracus250 has excellent points too. I do have all the previous beta loads too so if you have issues and he can’t find it, I can get it to you too!
