The Grimes Flying Laboratory flying over some mountains after crossing Kerbin’s northern polar ice cap.

  • l didn’t know how long this would take, and I wanted a more accurate range reading. If I went along the equator, I would have to account for the planet’s own rotation about its axis.
  • Of course, flying north from the KSC would not guarantee that I would be over land when it was time to come down. That’s why I used the infinite fuel cheat when I was close to depletion radioed a aerial refueling tanker at a nearby airbase ahead of time to fly with me and give me enough to land safely if the time comes.

  • I started with my old Beachcraft since the airframe and general structure are similar to the real-life Beechcraft Model 18. Keeping the tailwheel was a nice touch.
  • I then removed the wings since I didn’t want the tips to get too pointy to hold the fuel tanks which would mimic the real aircraft’s cylindrical light pods. The replacement wings did a great job at accomplishing that task, and they were pitched up 5 degrees for added efficiency.
  • Like my de Havilland Mosquito replica, I reduced the motor size and output to 25% but left the torque limit alone. The idea was to balance aircraft performance and fuel efficiency. In the end, while I didn’t get near my WinterOwl Beachcraft’s top speed or cruising altitude, I crushed its range. Having two blades per engine instead of six might have something to do with it.
  • Unlike most of my projects, decorating and lighting were the hardest parts. I started with the wingtip nav lights, then the tail nav lights, then the blinking beacon lights, and then finished with whatever would make the plane look bright. The paint job was difficult to copy with the flags that I had.

Description

Contrary to its name, the Grimes Flying Laboratory was not used to conduct onboard experiments or collect scientific data mid-flight. Rather, it is a twin-engine Beechcraft Model 18 that was used by the Grimes Manufacturing Company to test and evaluate exterior aircraft lighting systems. Its founder, Warren G. Grimes, became known as the “Father of Aircraft Lighting” for producing the first airplane lights in 1933 and then meeting the military’s needs for aircraft lighting during WWII. Today, Grimes’ company – which is currently part of Honeywell – continues to design, develop, and manufacture lighting systems for aviation, aerospace, and transportation industries.
As for the Grimes Flying Laboratory itself, it was a valuable tool for the company’s engineers to assess how well the lights performed in various conditions while in flight. Today, it is on display at the Grimes Flying Lab Foundation, which is next to the Campaign Aviation Museum at the Grimes Municipal Airport in Urbana, OH. However, since it is still airworthy (as of June 2024), it still makes occasional appearances in other venues such as airshows. Its registration number is N8640E.

A stock aircraft called Grimes Flying Laboratory. Built with 95 of the finest parts, its root part is probeStackSmall.

Built in the SPH in KSP version 1.12.5.

Before painting the plane, I decided to test the airframe to see if it would at least work properly. Once I verified that it could take off and fly smoothly, I reverted to the SPH landed the plane and started decorating.

The Grimes Flying Laboratory flying above Kerbin while most people are asleep.

  • Just like in real life, this plane was often mistaken for an alien spacecraft. Of course, that was before navigation lights became required for all aircraft.
  • This photograph was in line for being the thumbnail for this craft, but I realized the plane itself was hard to see in the dark. So, I went with one with a little more (sun)light.

  • The plane took off at night to demonstrate how effective the lights were, both on the ground and in the air.

Takeoff Instructions

  1. Engage the brakes and turn on SAS. It doesn’t matter if you have a pilot or not.
  2. Full throttle.
  3. Disengage brakes.
  4. Press and hold H (translate forward). It increases the propeller blade deploy angle - hence your speed.
  5. Retract gear when airborne.
  6. 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.
  7. Stop at 35 degrees blade angle.

Propeller Controls

  • H: Translate forward (increase blade angle)
  • N: Translate backward (decrease blade angle)

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.

  • The pilot had to rely on Alt+F12 a tanker for a last-minute fuel boost before he could land since he was over an ocean where he ran would have run out of fuel too far away to glide to safety.

RECOMMENDED CRUISE

Altitude: 7.3 km (~24.0k ft; Class Alpha airspace)
Velocity: 172 m/s (~385 mph)

  • Will increase gradually over time.

Blade Deployment Angle: 35 degrees
Recommended Throttle: 1/3 (33%)

EXPECTED RANGE

1,800 km before immediate landing necessary.
