Syma S107 - Change channels to fly simultaneously

Most RC helicopters come fixed from the factory on a certain channel and the helicopter's channel can not be changed. The Syma S107 however can bind to different remotes on 2 different channels so up to 2 can be flown simultaneously. Please follow the directions below to enable this feature.

1. To enable this function make sure both remotes and both helicopters are off.
   
   
2. Set the first remote's channel switch to the leftmost position (it says A, B, and C, but the s107 only supports 2 channels). Turn the remote on.
   
   
3. Turn the helicopter that you would like to bind to the remote on and set the helicopter down on a flat stable surface for about 5 seconds. Try the throttle and the helicopter should respond to this remote.
   
   
4. Next, to enable the second helicopter, set the second remote's channel switch to the rightmost position (it says A, B, and C, but the s107 only supports 2 channels). Turn the remote on.
   
   
5. Turn the second helicopter on and set the helicopter down on a flat stable surface for about 5 seconds. Try the throttle and the second helicopter should respond to this remote.
