EXTREMLY NOT continue your turn with acceleration on, for more than 6 secs because if you exceed the aircraft max speed witch is 30km/h your wing will fold up and brake and your bird will get ground faster than lightning (witch happened to me one mounth ago and fourtunatly i was flying in a 30 cm height grass field that absorbed the shock and kept the electronics safe !!!!)
I can vouch for that. Luckily I was in a wheat field when it happened to me! Once you hear that prop winding up more than normal slow it down.
I do suggest that you strengthen your wing with packing tape before flying in expert mode if you think you're going to kiss the ground with any force. Even in standard mode you should at least put a piece of packing tape on the back side of the wing just past the diameter of the propeller. If you land a bit off and your wing touches the ground first while your prop is running you will without a doubt take a chunk out of your wing.
