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 ?????

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.
If thi is a Reflex with two opposing rotors and two directional fans then use the "trim wheel" on the top of the rotor assembly to counteract the spin. If you crashed it often enough the shaft for the top rotor may have come loose. I'm not sure how this actually works with the trim wheel but mine crashed a bit and the shaft came out. I re-inserted it and it worked OK for a while but eventually the gear inside stoppped grabbing the shaft and the top rotor would not spin. I took it apart and tried gluing the gear to the shaft and that got the rotor to spin at the same rate as the lower rotor but I could not trim to get rid of the spin on the body. I would advise not buying the Reflex becuse it does not hold up very well. I went out and purchased a Sharpshooter which is easier to fly and seems more durable
Issue: Heli spins to the Left (counterclockwise) uncontrollably. Problem: Tail rotor not turning fast enough, Dragging. Background: My son's Heli Cage also started spinning to the left after he had flown it a couple 3 times. The trim and direction stick could not compensate. One time, the tail rotor came off during a crash. It was put back on and ran fine a couple more times until the dreaded left spin. I began to troubleshoot the issue. I checked for damage, hair and whatever else on the shaft. There was no obvious signs. When I pulled the tail rotor off, I noticed that it came off very easily. I put a new one on it and problem solved. Diagnosis: the tail rotor shaft was spinning inside the rotor. This prevented the tail rotor from turning the correct speed. Corrective Measures: replace rotor with new one. Avoid hitting the rotor while it is spinning...good luck! :-)
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
