Version 2.4: Replaced 6 bladed propeller pullers with 4 bladed fan pullers, increased cruised speed by >25 m/s!

Description

No Helicopter should be this fast!

Has more cargo and passenger capacity than its predecessors. Has a docking port for sky craning cargo and is proven to lift up to 28 tons in cargo. Improved range via more fuel tanks. All this at the cost of only 20 m/s in top speed.

Its side pullers control yaw and keep it straight against rotor torque (with SAS On). The highly dihedral wings allow for stable cruise. Reaction wheels are for stabilization against unwanted oscillations at low speed and do not provide attitude control torque. Has several flight modes:

  • Neutral: For flying at <15 m/s, slowing to a hover and precision landing. Rotor lifting is recommended.

  • Slow Forward: For flying at <50 m/s. Rotor lifting is optional.

  • Fast Forward: For cruising at >230 m/s. Rotor lifting should be off.

Warning: Do not activate rotor lift at full speed, to slow to a hover downshift to slow forward and then neutral when speed is below 60 m/s, only then can rotor lift be safely engaged.

Caution: Watch Electric Power Usage! Reaction Wheels suck a lot of power when maneuvering, you don’t need them except to prevent oscillations and drift at low speed so you can turn them off most of the time to keep batteries charged.

A stock aircraft called Compound Speed 2. Built with 67 of the finest parts, its root part is Mark1Cockpit. Built in the SPH in KSP version 1.12.1.
