RE: ??? before first attempt
tighten the blades up just enough to where you have apply GENTLE pressure to move them in their holders (about as much as poping the tab on a soda can). Straighten the blades by eyeballing them and then tehy'll line by centrifugal force when they spin up. The sockets do pop off the ball joint, as to how many times I am not sure but they are designed to do that.
If you live in the US and bought your product in the US then the throttle is on the left. Does it ratchet (clik) when you move it up and down ?if so then it is .....
the switches on the bottom are to reverse the servo settings.
moving the servos is ok when power off , they'll reset on power on BUT be very very gentle. You might strip the plastic gears if you are not careful.
