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.
Wait, Auto-WHAT?
Turn of all things auto. Play the game.
262 takeoff, any obstruction or airfield....NO AUTOPILOT!... Up on runway, hold brakes fully on during engine spool-up.... release brakes @ 8500 RPM. Allow jet to gather momentum. It will do what I call "the 262 hop" about 3/4ths the way down the runway. It will rotate into the air for a second, then settle back down on the runway. Allow it to do so, or keep the nose on the ground with slight forward pressure. Take the last couple hundred feet of runway, then lift the nose up. Rotation is generally at ~190 IAS. Fold the gear as soon as you lift. You can climb out to ~900-1000 AGL, or I prefer to level at 250 and build up airspeed to ~400IAS, and then climbout at 3K/min.
On the 163... you will love your plane a lot more, if you take off, level out at treetop height, and get 400 IAS built up. Pull the nose into a
GENTLE climb of around 30 degrees nose high, and it will
accelerate all the way through the climbout phase, and save you more precious fuel. I see so many people pull it straight up off the runway... you're wasting fuel (and sortie time) with a climb at 200 IAS straight up.
You can level off at 30K, with around 250lbs of fuel left, good for ~13 minutes at minimum throttle and 500 IAS.
