Hi man, try the help on the hitech board:
htchome click on help.
Throttle and rpms depend on which plane. When your at full throttle and press p (default if you havnt changed it) on the keyboard you get war emergency power (WEP) on most fighters.
That rises rpm and mainfold pressure a bit and gives a diffrent noise.
Why i say this is you can only engage WEP if you are at full throttle, so if you are able to fire up wep then you had full throttle before.
Take up a Spitfire V. Full Throttle on the runway should give 9.5 on the mainfold pressure, 12 or so with wep. 2900rpm and 3000 with wep, not totally sure since i cant check at the moment.
When you open the clipboard and click on E6B you see the readings you should get for that plane on Emergency power (WEP) and on Military power. Compare that with the instruments. (forget the max cruise for now).
Also acceleration is only good in lvl flight, hit x for autopilot lvl. When you are in a climb or in the CLIMB autopilot you wont exceed 180mph.
There are some slow planes out there... but 180 is pretty low i think eaven a C47 is faster.
keep asking, best is to ask questions.
In training arena most of the time a trainer is online and if not another player might help for a short flying lesson.
