YES IT DOES SPIN IN CIRCLES VERY FAST WHEN YOU GIVE IT MORE THROTLE .THE GYRO IS A JRG500T AND THE SERVO IS JR DS285. WHEN I SET IT ON THE FLOOR IN FRONT OF ME AND FACING ME AND TURN THE ROTOR BLADES CLOCKWISE THE TAIL BLADES TURN BACKWARDS WITHOUT THE RADIO EVEN BEING ON. IS THIS RIGHT ? IT WILL JUST SET THERE AND SPIN IN CIRCLES. HOW CAN I TELL IF IT IS REVERESED? I SURE THANK YOU GUYS FOR YOUR HELP
