Why won't my Horizon Hobby Toy helicopter respond to the throttle?

If your Horizon Hobby Toy helicopter responds to other controls but not the throttle, start by ensuring the throttle stick is at idle and the throttle trim is not too high; lower them if needed. Verify that the transmitter is in normal mode and throttle hold is off. Check the connection between the motor wires and the ESC, inspecting the wires for any damage. Also, ensure the flight battery is adequately charged; replace or recharge it if necessary. Finally, confirm that the throttle channel is not reversed on the transmitter; if it is, reverse it.
