Yea for Lukla you should be around 80 knots on the final approach, there is no go around procedure so it's imperitive to be at the right approach speed, only get the one chance.
on flightsim.com there is a fantastic free addon for Lukla airport, it's close to the real thing and a hell of a lot better than the default Lukla, check it out.

lol just noticed that tree in front of the run way! WTF that is not supposed to be there, try to get the add on.
Also don't apply brakes until all 3 wheels have touched down!
