This is so cool!
One Aircraft that I can really recommend for all the airfields, is the Bücker Jungmeister. It has good STOL-capabilities and the engine is strong enough. The Extra and the Pitts are also no problem in Lukla, though quite a challenge in Syangboche (but it works!)
Q400 also works in Lukla, but only just... On my first take-off with normal flap setting I stalled and burned to death, but on second try with almost full flaps I was able to takeoff and also to land (on first try, without dying! ), approach speed 120 knots, touchdown at the threshold, immediate reverse thrust and max. braking.
The experience in VR really makes this a 10/10. Amazing!
