Question about Axial Syma 9086 Helicopter
I was recently given a Danbar rescue copter 3d. It rotates in the air without pulling control stick. According to the manual I "can stop the fly, use screwdriver to adjust the potentiometer on chopper circuit board lightly". The only phillips screw I can find is holding the drive gear to the bottom of the rotor shaft.
You can adjust the trim under the stick on the transmitter and/or the trim screw on the helicopter. If this is still not enough the motors will need to replaced so power matches.

usually trim adjustments are on the controller... not on the vehicle itself.
a potentiometer os a fancy word for dial adjustment. It wont be a metal screw, but probably a metal square with a plastic looking slot that can be turned. usually white or blue plastic

This type of helicopter uses a fixed pitch blade. Have you recently replaced one or all the blades? If the blades are correctly positioned then once the motor comes to speed, the pitch of the blade creates enough lift to overcome the force of gravity. The problem you're having can only be that the motor is not coming to speed or the blades have been replaced but the pitch is now at the wrong angle.

When the controller flashes, it means that it has not paired up the signal with the helicopter. Move the accelerator control (left stick) up and down quickly several times. The rotors should start to turn signalling that they are paired. Max out the stick forward and back quickly.
