Welcome to your new addiction ISHAWA

!
This thread will help you with setting up your mouse. But i recommend you get a Joystick ASAP - youll get to know a whole new, better AH! Doesnt need to be anything fancy for beginning,
check here.
Now onto your questions:
The buzzing sound you hear is your
Stall Warning. If you slowly keep pushing it, it will get louder and louder, eventually ending up in
Stall Buffet (Shaking and machine gun sound) - loss of control (control surfaces wont react to input anymore). What you need to learn is "riding the edge of stall"... pushing it for performance, but without loosing control.
Stall usually happens because you get too slow. Theres also acellerated stall which happens at high speed. Do a search in this forum, a short while back BadBoy posted a great explanation on that.
For now remeber two things: Keep a minimum amount of speed up (depending on plane, but 150-200 mph for maneuvering is a general number). And always be gentle with that stick(mouse) of yours - no hard, jerky inputs.
If you pushed too far (into buffet): Nose low and straighten out and gain some speed back before starting to maneuver.
If you are fully stalled out (spinning) - Flaps up, nose low and rudder input opposite to spin direction.
On another regard, also do yourself a huge favor. Go to OPTIONS > PREFERENCES > Flight on your clipboard (ESC key) and turn off the
Stall Limiter. This is a code that limits your AOA (angle of attack) - in other words limits your turn performance by keeping you from pulling into stall/blackout. Its like training wheels - its better to never get used to them at all.
Climbing: Climb rate depends on a lot of things. Plane type, fuel/weapon/ordenance loadout, altitude, speed, engine settings (rpm/MP/WEP)....
To get some altitude to work with its best to use the autopilot:
X - autopilot level
ALT_X - autopilot speed (plane is kept at a preset (ideal climb) speed - at full throttle it results in autoclimb)
SHIFT_X - autopilot angle (keeps the plane at the current climb/descent angle, no regards to speed - if you set it too steep it will result in stall or compression)
When using mouse, toggle mouse flight control off and on (default key is H)before hitting autopilot key - this will "center" your flight controls, otherwise mouse input will keep throwing you out of autopilot.
When climbing manually, always keep an eye on your speed, stalling out will *cost* you altitude, not gain it. Never climb into buffet. Always remeber were WW2 here..... climb rates are usually between 2000 and 3500 ft/min. (A few notable exceptions).
Taxiing on the ground:
Use your RUDDER to steer the plane. A and D key for left and right, S to center rudder. To assist in tight corners, use the seperate wheel brakes C and V.
Pulling back on your mouse slightly will *lock* your tailwheel, keeping your tail from fishtailing. (Especially neccessary when taking off manually).
Youll notice that if left to itself, every plane will go in a circle on the ground. This is several effects from propwash and prop, usually simply called "engine torque" - the more engine power, the stronger the effect. Direction of the circle will be opposite prop turn direction, for most planes thats to the left. The same effects are still there when in the air, but a lot less noticable. But this still means each plane has a "favorite turn direction". There are planes with counter rotating props like the P38s - they suffer no torque effects at all.
To counteract torque on takeoff, lock your tailwheel and use RUDDER input to keep your plane straight. (Note that with nose wheelers youll have to push *forward* to lock nose wheel!)
So.... now i wrote a whole lot more then i intended to

. I hope i didnt flatten you with all that.
