This is not just a visual upgrade. It became MUCH closer to the real helicopter!
Older version mostly floats by jet power, but this one actually floats by wings!
It's more realistic, easier to control, smaller, stable and faster!

I replaced rotators with structual wings. They are much lighter and stable, so that the rotor can spin much faster.
Agility and stability can be adjusted by changing dead weight of structure, but it's little bit difficult.

[Controls]
You can roll, pitch and yaw. VTOL up to go up. Throttle 100% is full power, but you can save fuel by keeping it around 75%.
Keep VTOL +40% and adjust throttle will be easiest way to land.

I will make another attack helicopter next time.
Have fun!

P.S. Thanks for silver. :)
