I am able to get the Chinook in the air, and I have the stabilisation thing set to "both". However, I find it impossible to stay in level flight with this aircraft. Even a tiny amount of collective causes the vertical speed gauge to go crazy, and I then spend some time trying to get it to settle back to zero where the aircraft is not massively climbing or diving. Does anyone have any tips on how to maintain level flight in this aircraft or to reduce the sensitivity of the collective please? Thank you in advance.

I'm thinking of upgrading the stick and throttle on my simrig from the T1600M I currently own. I've decided I am getting a gladiator premium for the stick, but I can't decide on the throttle. The STECs mini looks great with the extra hats if I also buy the button and magazine module, but the Omni throttle is so much cheaper in the UK. I fly both Helis and aircraft. Does anyone have a view on the STECs Vs Omni throttle? Do any DCS players actually use the Omni throttle? Love to hear your thoughts folks.
