RE: Wing tip stall
Tip stalls happen for a reason. That tip is too slow to fly, at that moment, in that AOA, in those wind conditions. You see, many factors contribute. Simply avoid the whole thing by keeping your airplane well above stall speed. Not too difficult really. You can tell when your control is becoming 'mushy' and difficult. In those conditions, a stall is only a heart beat away. Add more power.
When landing, for aerobatic and most sport planes, get the tail wheel down first and the wings will follow. For most war birds, fly it to the ground on the main gear, and let the tail come down when ready. There is more to it, but those are the basics.
