Description

A stock aircraft called Hawkmoth. Built with 31 of the finest parts, its root part is MK1Fuselage.

Built in the SPH in KSP version 1.3.0.

The purpose of this little jet is to fly contracts of the kind Take temperature above/below X at Y.

It is very fast and has enough range, and it can go above 19km as some contracts require. Just pick up enough speed (800m/s) and pull up 45 degrees, and it will easily climb to a 40km apoapsis.

Takeoff and land at 80m/s.

In addition to the Panther engine, there are two Junos that help push a little to get it up to speed.
However, they will flame-out at about 800m/s.

The airbrakes will violently bring the speed down to less than 300m/s within just a few seconds - while making Jebediah pass out in the process :D.

If you’re using the Kramax autopilot:
The craft flies stable manually and with SAS turned on, but the Kramax autopilot starts oscillating the pitch at around 700m/s. The default control loop characteristics are just too violent for very high speeds, so you need to tweak its settings a bit to stop the oscillation. You can see my settings in the screenshot above, but here are my values again:
Vertical section, Angle of Attack PID controller: Kp 0.005, Ki 0.2, Kd 0.1, Scalar 3.0
You can save this as a preset.

Range: plenty
Confortable cuise speed: 800m/s (half throttle, wet mode)
Max Speed: 999m/s (engine will overheat and blow up)
