Slider 1 is propeller pitch - you need to set it all the way up or there's not thrust from the prop! lower it once airborne maybe, up to you. I think it's meant to be more fuel efficient or something but I could be wrong I'm not an engineer or anything I don't actually know what the point of manual control on this is, but I had it unlocked so why not.
Slider 2 is flaps. idk lol they're meant to give the plane more lift at lower speeds for takeoff/landing or something but they don't work very well.
My first real attempt since the tutorial at building a plane in this game. Modelled after an Extra330. It doesn't do the best with aerobatics, but it flies nice and stable, has plenty of pull and no trouble recovering from a stall. It has range for days, I flew it from Juno Village to Ali Pad on less than 10kg of jet fuel.
Not sure if this is intended or Fuel Cell is bugged (the cell output is <1kW and prop motor requires about 95kW, but it flies fine on cell power alone with a dead battery)
Just sharing so I can import this to my Android copy of the game, why not make it public I guess. It's all vanilla so should be usable by anyone, requires a few tiers in propellers and wings if you're playing in career mode.
