TC yes, OP was talking about heli engine fuel flow controls. For a FW throttle you push forward to climb, pull back to descend. Fuel control levers on helis the same, pull it back, you are going to be descending!
The cyclic is connected to the Main AI (directly). Push it fwd and the AI shows descend and the helo goes down as well as fast. Pull the cyclic back, the AI shows climb,
Must try that in the hover sometime!
