The 2nd variant in my LXR2 series, and the shortest in length. It's the Roberts LXR2-100

History

Oct 2022

I first came up with the idea of an airliner in Oct 2022, while planespotting from a hotel room balcony in Queenstown. It was a top view that was very basic, but would be the beginning of a long journey.

Development

LXR1 similarities

Before I started designing the prototype, I had already made the LXR1 turboprop, which was the result of someone (who shall remain nameless) saying that basically, I make planes that are somewhat mediocre. And they were right (sort of), so I stepped up my game with the LXR1. For my LXR2 jetliner, I decided that the nose design would be based on the LXR1.

July 2023

This is when I drew up my original blueprint(s) for the LXR2-9 (later the LXR2-300) (replacing the original top view), and it was my most detailed drawing I’d ever done. I would commence the actual building of the plane shortly after, on a flight from Wellington to Brisbane.

VR decision

When I started this project, I had no intention of adding a VR cockpit. I had thought about it, but didn’t actually make one until later, Once I started, I didn’t stop.

Prototype in Nov 2023

I unveiled the LXR2-300 prototype in November 2023, with links to the other unlisted variants. The first stage was complete: Hit the ground running with a fully functioning prototype. But the second stage was already well-underway: Continue development for the production model.

Design

The design has been inspired by both the latest jetliners and my LXR1 turboprop, with the semi-blended wingtips, high bypass engine design, and the single-slope nose.

Changes from prototype

At first glance, the prototype and production LXR2-100 aircraft look rather similar. Look closely, however, there are a multitude of changes:
- Updated Landing Gear
- Redesigned wings
- Redesigned flap mechanism
- Opening doors
- Redesigned Cockpit (see Cockpit section for more info)
- AoA sensor (don't worry, this one works properly)

Cockpit

Prototype Cockpit:

Production Cockpit:

The cockpit is likely the largest change from prototype to production. The fully digital display has been replaced with a neat layout consisting of both analogue and digital readings. The compass and artificial horizon have been combined into one. There's now somewhere to put your legs. The joysticks have been replaced with control columns. The throttle control has been redone. The VR grips and switches have been brought closer towards the cameras for easier reach (including a lower cockpit ceiling), and are white with a slight emission for better visibility at night.

Gauges and measurements

The analogue gauges measure in the de facto measurements in aviation (feet, knots, etc), while the digital readouts below each gauge and in the centre are either metric or percentages, and are mainly de facto aviation measurements everywhere else (the digital fpm readout is to the nearest 100 fpm).

Much of this aircraft wouldn't be the same without their airliners.

This video on precise rotation was very useful — I now use small rotators for basically anything that rotates.

I decided that the map from GuyFolk's [AI] auto ejecting Wasp-B would be very useful in terms of navigation and travelling to locations beyond the map boundary.
