The Wasp Super Micro Helicopter, one of the the smallest and technologically advanced helicopters in the world! Utilising a tri-band control system - A, B & C, three helicopters can be flown at the same time. Recharging takes place via the transmitter, and also the transmitter has the alignment trim, a charging/power indicator and a left/right lever. The helicopter is supplied in yellow or black. The helicopter is powered by a fast charging flight battery, and it also has a small blue LED strobe light that flashes when in-flight for night flying. When the helicopter crashes, the motor will automatically cut off the power. This will protect the motor and increase the product life span. Most of the mini helicopters in the market currently do not have this feature and it is a common cause of helicopter expiry! Current mini helicopters on the market are using standard electronic position IC for the remote trimming adjustment. The Wasp is equipped with the FULLY Adjustable Position trimmer. This functionality is usually only available on scale model flying machines, or 4 Channel helicopters.
