    finally i fixed by changing the mode on the radio and fixed it.

    but i have another question is that i download the Arducopter 3.0.1 on the internet and update the firmware by arduino.

    however, the setting which i setting by MP are clean.

    So , is there any ways to download the firmware which is on the board or in the MP?

    As Ray say, i fix it by reverse the second servo on mp. 

    But there's other problem that my radio's pitch and throttle are separate.

    For helicopter, pitch and throttle should be controlled at the same putter.

    My flight mode are set as Stabilize, loiter and position. I might change to Acro, Stabilized and loiter.

    By the way, i use Futaba T12FGH and R6014HS as radio and RC. 

    The connect between RC and APM are ：

    1-2

    2-4

    3-3

    4-1

    5-5

    6-8

    7-6

    8-7

    I try many time to get these connection, but i'm not sure is good or not.

    What flight mode are you in? Get everything working in Acro first, then move onto the other flight modes.

    Using mission planner, does the autopilot think it's level when sitting on a flat surface?

    Do you have your transmitter turned on with the sticks centered?

    Have you properly adjusted the range on all your servos? (both input and output)

    Have you properly adjusted the center point on all your servos?

      Nate what you mean about ranging all servos(input & output) I just range my radio calibrated and Supposed that it also calibrate servos. I have some problem connectiong APM2.5 and DX8. Do you have any advise?

    I may be as easy as setup.  You will have to reverse the second servo in the mp software and then I also had to reverse the pitch in my futuba radio.  It's not necessarily a problem.  Just look again at the trad heli configuration tab in the MP it may fix it.
