Featuring realSavageMan's Fokker Dr. I on the second thumbnail picture.

L.T-2S Mark 1

The L.T-2S is a fighter prototype built in 1916, and made it's first flight on late 1917. The L.T-2S nicknamed "Armed Kite" by the pilots due to it's agility at low speed. This build, however, was a restored and upgraded version of the actual L.T-2S, featuring the improved cockpit dashboard, engine starter motor and battery, retuned 9-cylinder radial engine, and overhauled airframe.


  • Simulated left turning tendencies
  • Realistic Engine startup sequence
  • Low part count (172 parts--ultra mobile friendly)
  • VR supported
  • Simulated gun jamming (10 seconds of continuous fire)


2x 7.7mm 450rpm machine gun


Throttle - Fuel injection
VTOL - Propeller Pitch


Fuel Valve - Controls fuel pipe valve, fuel valve needs to be opened to use Throttle
Engine Start - starts the engine with the starter motor. Note: starter battery has limited energy, the energy amount are showed at the far right gauge. leaving it empty will cause engine start motor becomes inoperative.


  • Pull the Throttle and VTOL(Prop Pitch lever) all the way back
  • Open fuel valve
  • Engage Engine Start until RPM gauge needle raised past 1 bar
  • Throttle up to 50% until RPM established above 1000RPM (Engine Start switch must be released, otherwise the engine start clutch will prevent you from spooling up the engine)
  • Throttle back to 25% until RPM is idle at 1000

To shut down the engine, pull Throttle to 0%, or shut off the fuel valve.

    Side note: don't push the prop pitch up suddenly, as the torque kicks in and makes the aircraft just spinning around. Instead, push it progressively as the speed increases.

    This is lovely! I should have a go at a WW1 aircraft like this. :)

    Nice but complex for some amateur like me.

    @BangRou Thanks for the response. I'm a bit of a newbie to simpleplanes so I'm still educating myself, for instance, I'd never heard of propeller pitch until I looked at your plane. Anyways, nice work !

    @Oculite1 nope, back then WW1 airplanes spools up their engine by manually spinning the propeller. This build was intended to be my engine startup testbed, but I went too far.

    Nice build with an interesting start up procedure. I'm curious, is that the way a lot of WW1 planes fired up their engines ? It works great in VR by the way !

    This is probably just a me problem but right rudder on the ground just makes me go in a circle
