WK-0701 throttle adds to roll ?

[viva_unix]

Hello!

I was trying to get a lift off with my walkera 60 and could not do it in real life. So, I got the RealFlightG4 simulator to get skils for ligt off. After trying for 2-3 days I have noticed that my remote control WK-0701 works a little stranged. When I add throttle it automatically adds the roll (not pitch). So, it is hard to stabilize the halicopter. As a result the helicopter moves in circles or crashed.

Anyone know how to fix it? Should it be done this way? I read online that throttle should add a little to pitch, not to roll. Are any combination of switches in the back can fix it?

Thank you!
