Um...not entirely sure how much help I can be, but I will try.
Firstly, I'll try to sort out your questions from what you wrote.
1) Can I make the game more difficult so that the enemy attacks me when I'm in their airspace?
2) What can I do to avoid stall on takeoff?
3) Why doesn't my gear lower?
Assuming that the above are the correct questions, here are my answers:
1) The only thing I can possibly get from this is that you are playing offline and wish for the drones to attack. Sorry, they don't. You want some enemies to attack you, come to the main arena, join either bishop or knights, and tell me where you are. I'll gladly bring my rook pony over to help you out.
2) If you are using auto-takeoff, you shouldn't be stalling out, unless you are attempting to roll off a carrier with a heavy ordinance loadout. If it stalls out once you are airborne, is it because you attempted to make to radical a course adjustment?
3) There was another post regarding this recently. Unfortunately, I can't help you with a resolution. Just make sure that you are travelling slower than the maximum deployment speed when you try to lower them. Try looking in the "bugs" forum...there might be an answer there.
