To begin in controlling the tail spin on your helicopter you need to turn your helicopter on and then turn the controller on. On your controller there are two trim bars. If it begins spinning to the left, tap the right trim; likewise, if it begins spinning too much to the right, tap the left trim. Unfortunately there is no memory in the PicooZ helicopter, so every time you turn on the helicopter you have to trim it. In the example video the helicopter needed to have the trim bar pressed 12 times. This is typical. After proper trimming it will stop spinning. However, you may find that you need to trim it occasionally as the battery begins to die.
