Helicopter spins left and rear rotor does not spin at all
On my first flight I crashed into the sea, don't laugh, wasn't at all funny as I had to dive in to retrieve it. Washed down everything with fresh water, dried it off and tested. Main rotors are fine but after trimming the left spin as far as possible it still spins left. Also the rear rotor does not spin when plugged into its socket on motherboard. Does spin when change to different socket, but spins constently which is not good. Maybe the motherboard is screwed ?????

adjust the trim on the controller please watch some beginners videos. In this instance the problem is yaw which is left and right rotation on a helicopter it is affected by the speed of rotation of the tail rotor relative to the speed of main rotor and its gyroscopic effect. the floor cause weird flight effects on helicopters to get the trim precisely set it must be at least 4ft from the ground. but initially just get it to where it is controllable.
add small counter weights on copters plastic body just enough to allow motor to spin without dragging the body and spinning while in flight. check if motor's rotor shaft comes in contact with copter's body, make adjustments on it
When the crash happened, was the throttle gimble on the transmitter left at a throttle up position for any length of time? If it was, it might have burned the speed control or electronic gyro for the bottom rotor blades. Replacement of PC Board might be a fix.
I had the same problem. Bottom blade would not spin. There are 2 shafts that spin 2 gears. The outer shaft that spins the bottom blade has 2 set screws and my set screws got sheered off. I replaced both set screws and everything works now....
We are a family that bought one of your helicopters. We immediately had a problem, the top rotor stopped spinning after a crash. We found out that when the helicopter crashed I wasn't paying attention(I am 10 years old)and I was still pushing the throttle while it was on the top rotor. Big mistake,when I tried again it Didn't lift off the ground. We then put crazy glue in between the top rotor and the shaft and tried it again. It worked! Both rotors spun! Good luck!
If its a Reflex twin rotor Heli use the trim wheel on top to counteract the spin and at least stabilize the craft at hover. Then use the right/left froward backward fans to control flight, (right joystick on the controller). These fans are not very powerful so don't expect alot from them other than turning the craft right left and reverse. Seems there is too much down draft from the rotors to effectively move the Heli forward. Not a real good design. The Sharpshooter is easier to fly but uses the batteries in the controller as a charger so they don't last real long.
make sure there is no debris such as hair thread or string caught in the back rotor. this will cause it to lock up. Remove it and try fiddling with the trimmer button to help it stop spinning the helicopter
