These will overwrite part configs for all partmods this craft uses. Make a backup of your gamedata or simply create another installation where you install these before merging the folders.

This simply changes mass for some parts (not all) and increases power to the rotors. I’ve also modified RSE to add the prop noise directly to the rotor engine as without this they make no sound (props need to be attached directly to the rotor originally)

A modification of my OH-58D, I’ve fixed the issues my Kiowa had with its rear and streamlined the bodywork a tiny bit. Also obviously had to change the area around the engine. All of this took about 2 days to complete. Doing this made me realise I’ve built my Kiowa to a JetRanger spec, and not LongRanger. Going to apply these changes to the Kiowa eventually.

My main focus was to make it look good and to keep the main rotor as simple as possible. Due to this, it flies absolutely beautifully. Very smooth, I recommend flying this with fine controls enabled (caps lock).

Action groups:
1. Initial startup of both engines
2. Shutdown both engines (also used to re-start them again)
3. Toggles cockpit doors (locked by default due to wobblyness)
4. Toggles passenger doors
5. Toggles landing lights
9. Unlocks cockpit doors

Carries up to three passengers and has enough fuel to last you to the runway island and back, with fuel to spare.

As with any of my builds this requires some modifications to part configs. Although you might get away with leaving the rotor as is.

Weight: 8.182t (in my installation)
Cruise speed: Around 52 m/s
Max speed: Untested (I’ve hit 85m/s without issues in dives)

Currently only available in Business Blue™

Huge thanks to Rpatto92 and his helicopter guide. Without it I wouldn’t have even tried building working helis in this game.

Built in the SPH in KSP version 1.12.5.
