I have updated a helicopter that I uploaded during the beta test and that kept this copter from being seen or downloaded by a lot of people. So I'm revisiting it today. The changes I made improve the performance quite a bit. I modded my own VTOL engine to ouput the power of 4 engines. And the VTOL nozzels have also been modded so that they only turn 15 degrees. That way they don't add thrust or lift and only turn the rotors. Plus the fuel tank now holds 1000gal, this should be plenty and help get the part count down. I do feel guilty about using modded parts though.

The Sly HA100B is a high performance attack aircraft capable of over 120mph in level flight, and is able to perform back-flips with ease. It has been equipped with six rockets and retractable landing gear to reduce drag.

How to fly.
1. Activate group 1
2. Set throttle to 100%
3. Raise VTOL control and kiss the ground goodbye

Firing Rockets
1. Aim
2. Activate groups 3, 4, and 5, to launch

Raising landing gear (optional)
1. Deactivate group 1
2. Raise VTOL up fully
3. Activate group 3 until gear has retracted fully, now deactivate.
4. Return VTOL to desired setting and reactivate group 1

Lowering the gear is the same process only center the VTOL control instead of raising it.
