KWOD Kopter!
The very first 4-rotor helicopter in the Kermansky line. It uses 4 Juno engines and 4 Twitch rocket engines to spin the turboshafts. When you inititally launch the KWOD Kopter, you will need to use both the Juno and Twitch engines to take off. Once your craft weight drops below 5 tons, you can hover using only the Juno engines.
Approximately 5 minutes of flight time. Very maneuverable.
