Hi Stigjones.
Hope you liked it over here :)
Helicopters have two methods of control of the rotor blades. Cyclic pitch control and Collective pitch control.
Cyclic varies the pitch as the blades turn (eg, up on one side, down on the other). Each blade is controlled independantly, and one might be up while the other is down.
Cyclic gives you forward/backwards/left/right movement.
Collective pitch varies both blades in the same direction, at the same time, and maintains is regardless of where the blade is at that time.
Collective gives you up/down.
It's collective that you may be having problems with. Either collective pitch or rotor speed (RPM).
When the motor is disconnected and you are holding the flybar horizontal, if you "Throttle up" the pitch should increase positively (eg, the trailing edge of the blades will dip down). At maximum "Throttle" or with the throttle stick all the way up, there should be a noticeable pitch increase, while with the stick down, there will be negative pitch (ie, the blade trailing edge will be higher than the leading edge).
If you don't get enough positive pitch, then you may need to adjust the transmitter.
If when at "Max Throttle" you adjust the two knobs at the top, and the pitch changes, then you know your transmitter is unlocked and not set. Then that would be your problem. Otherwise they may still be out.
If you have plenty of pitch at the top, then it may be a power issue.
Don't be too wary of the hobby shop. Even if they don't show you how to set up, if they set it up, then at least you can use this as a yardstick to know what it should look like when it's set up correctly. (For when you do learn to adjust it later).
