Ok, I'm striving with the apple delivery mission.After getting to the first two air strips, my buddy says to pass over the mountains to get to the third one, so I set autopilot to get to 6000ft (700ft/min VS) full throttle.When the plane climbs through about 5000ft, it starts bleeding speed, manifold pressure drops to 0 and it drops into the ground like a brick.I tried playing with fuel pumps, cowl flaps, mixture settings, but I don't seem to get anywhere.Anybody can help?Tnx!!

I tried playing with fuel pumps, cowl flaps, mixture settings, but I don't seem to get anywhere.

Two other things that may matter: I switched all heaters on before takeoff and left them on; I didn't touch prop control.Which ones do the trick?
