Our line of 3.5 channel RC helicopters with gyros are the newest and easiest beginner RC helicopters to fly. With the built in gyroscope, you will easily be able to control your helicopter to fly up, down, left, right, forward and backward. The 3.5ch RC helicopter with gyro is similar to standard 3ch helicopter except the 3.5ch RC helicopter has a built in gyroscope that auto adjusts the yaw (left or right tail swing) movement to stabilize the flight. With the gyroscope feature it will be much easier to control your helicopter.
The 3.5 designation was previously used to distinguish helicopters with gyro but now all 3 channel models come with a gyro so the the terms can be used interchangeably.
