Above: Album of the circumnavigation test flight.
Details
- Type: SPH
- Class: aircraft
- Part Count: 111
- Pure Stock
- KSP: 1.12.4
Description
Based off the Eve drone prototypes, this aircraft is designed to carry three people and a science station across Laythe using solar power only. But first, it needs to prove its usefulness by flying around Kerbin and dropping off a science station somewhere.
Named Impulse
because the guy who designed this kind of proposed this on impulse.
A stock aircraft called E-40 Impulse (PLANE ONLY). Built with 111 of the finest parts, its root part is Mark1Cockpit.
Built in the SPH in KSP version 1.12.4.
Takeoff Instructions
- Engage the brakes and turn on SAS. It doesn’t matter if you have a pilot or not.
- Deploy flaps (Action Group RCS).
- Full throttle.
- Disengage brakes.
- Press and hold H (translate forward). It increases the propeller blade deploy angle - hence your speed.
- Retract gear and flaps when airborne.
- Keep tapping H as necessary to keep optimal blade angle (which maximizes thrust). It is recommended to tap rather than press and hold for fine-turning blade angle. Best blade angle for maximizing thrust is 45 degrees, but you do what works best for you.
- Be advised that you may need to slowly lower blade angle again at some point. When that happens, translate back using N.
The E-40 Impulse loaded with the equipment necessary for a science station.
- I put the
PLANE ONLY
part in the name since at the time I first designed this, I planned to send this to Laythe once Kerbin testing was complete. I still do, so stay tuned for the Laythe variant.

- It was completed in 5 hours, 11 minutes, and 30 seconds.
Landing Advice
After you land the plane, (unless you’re all done with it) press and hold N to return the blade angles back to 0 before taking off again.
RECOMMENDED CRUISE
Altitude: 7 km (~23k ft, which is technically Class Alpha airspace)
- Expect a near-negligible altitude drop, but you shouldn’t have to worry about it.
- In my case, it dropped ~10 meters for a 5-hour circumnavigation flight. That’s not too bad.
Velocity: 200 m/s (~450 mph)
Optimum Throttle Level: 2/3
The E-40 parked in front of the Temple of Tut-Un Jeb-Ahn. Since the plane was loaded with science station components, I decided to set up a science station there. After all, what archaeological work site wouldn’t have one set up?
- I admit I have no idea how they’re supposed to work. I loaded them in the plane for when I do learn or when other kerbalnauts need them.
