This newer version no longer has the problem of the tail rotor getting hit by a flare. The Enzyme is meant to basically destroy whatever you want, while being able to be a fun leisure heli. I can promise you a great time with this one, and have fun my people. VTOL lever for prop trim (you can also look down in cockpit view and see the VTOL and Throttle levers) the VTOL handle should never go past the first notch, only in extreem cases should it even go above the first notch a little. Throttle for throttle, I usggest having the throttle bettween 50-60 percent for maximum efficiency, but for agile flight you may want 100 percent. This aircraft can go up to 200+mph, forwards, however it is best to try and keep it to a max of around 150-160mph for maximum control in flight. Run on high physics. 1 for landing lights, 8 for interior lighting. Lastly, have fun my guys.
