I would consider paying $15/month to not play the game.
Talk to Hitech about that, I bet he would be ok with that.
Anyhow, easiest way to take off a 262 in my experience is let autopilot get you above treeline, then hit level autopilot. Get 250+ mph then hit climb autopilot and if the nose dips at all cancel climb autopilot and use level autopilot for abit longer. If you dont know you're starting to nose over, open those eyes and look at the gauge for your pitch attitude. I use this because for some reason if I leave on autotakeoff when it transitions to autoclimb in the 262 it does this teeter totter crap where it noses down to gain speed, then noses high to lose speed (it doesnt stop till I level it out.) So I work around that and it works better imo.
As for taking off in the 163 just let it autoclimb, cuz the dang thing will go nearly straight up... if you want to conserve fuel, throttle back, or just dont fly the thing.
