The dip switch on the back #8 must be flipped to "unlock" the knobs on the top for the following adjustments.

Try turning down the knob on the top left (PLT).
And turn the knob on the top right up a little (PIT).
This will make the helicopter less likely to jump off the ground and act more like a fixed pitch helicopter which I think also makes it easier to learn. Don''t turn up the pitch (PIT) too much because you do want the blades to spin up at a fast rate... too much pitch and the blades, motor, will bog down.

And also it's a good idea to get some rubber bands and secure the switch top right front in the
"N" Normal mode so you don't accidentally flip it to the "1" mode which is 3D (aerobatics mode).
