Just curios to what made you choose 35cm for the extension size. I think the biggest one I've seen on a thrustmaster is 20 cm.
As for the FM, we are tweaking it based on conversations with real Gazelle pilots. Our goal is to make the FM as realistic as possible, and we will continue to do so.
Since nobody at home has the actual Gazelle inputs, adjustments might need to be made to mimic the real inputs with your joysticks. I don't have an extension on my thrustmaster yet,but I fly pretty much with no curves and can fly along fine. But with other helicopters, I have to add curves and make adjustments to make it flyable for me.
To summarize:
FM: getting tweaked to make more realistc
Inputs: Unless you own a Gazelle, inputs will need to be adjusted to match real gazelle characteristics
Gun and Rockets: Coming soon!
Dan Quale: Still gaining acceptance.
