    @Sleet01 u definetly know ur stuff man :D
    I expected helis to be way simpler than that XD, guess i was so wrong....
    I am studying the model however and will start in my first heli in a couple of days due to a heavily busy academic schedule so wish me luck on both XD

    @BigBeast I made this while double-checking the heli building guidelines for your post. Of note:

    • This ship is probably a bit overpowered, as it can hover at 50% collective (VTOL) while fully loaded. I could reduce the power or the rotor size slightly and it should still fly.
    • The tail rotor is set to Head[ing] Hold mode, as I find this easier to fly on mobile. Rate mode is probably more realistic, but far harder to fly without a flight stick (or pedals).
    • The vertical and half horizontal stabilizers are not strictly necessary, but they improve control at higher speeds.
    • Despite what the stats say, the rotor disk loading for this heli is about 5lbs / ft^2, right in the 2 - 10 lbs / ft^2 zone.
