Just a couple other things to check, along with all the other good advice so far...
If you are correctly calibrated in both Windows and AH, you've checked your connections to make sure nothing is loose, your gear and flaps are actually up, and you've checked and set the apprpriate "dead band" on your stick...
...then also check your loadout. Full bomb load, full fuel, full ammo...and you'll be low, slow and heavy on takeoff. Using Auto-takeoff, a bomber in this trim will climb out on the edge of stall for quite a ways. try to do it manually and you only get one mistake before faceplanting on the asphalt.
Try lightening the load and see if performance improves. Especially critical if you try a carrier landing! Can be very tricky with a fully-loaded bird. FWIW...I agree that Auto-takeoff is a perfectly acceptable tool...even good sticks use it to simplify things while they get ready configured and ready for the upcoming fight. No one knows the difference anyway...unless you go manual and plant 'er tail up in the fringe!
For the mike...make sure you have checked your key mapping. IIRC, the range radio is f12 (?), and tuned channel is T. You are either using the wrong key, or no key is currently mapped for that command. Also, mic has settings in AH, as well as Windows. Make sure that mic level is up high enough.
You'll love this game, and this config stuff is just part of becoming intimately familiar with your ride. You will discover tips, tricks, little knacks for getting specific things done...they go on endlessly. Easy to learn...very hard to master! That's what'll keep you coming back for more.
Lastly, Shatzi is right. The TA and NetAces are the bestest place to start. And start yourslf a Flight Manual!. Laugh now...you'll use it later.
Good Luck!...you won't find an equivalent gaming community anywhere else.
