Top Tips To Flying Remote Control Helicopters Upside Down



Operating an radio controlled helicopter is not as difficult as a lot of people beleve. It is suggested that a flight slimulator be used if possible a 6 channel version.

The initial aspect is the actual building of the model heli itself followed by trimming it. When trimming ensure that the recommendations in the models instruction booklet are followed. It is essential that flying an RC helicopter upside down is one of just a few tricks which you cannot perform using training equipment. The counterweights will make the base of the heli be pulled back down if training equipment is used.

The recommendation is that the pilot does not attempt this trick immediately with the actual model but in fact practices with a simulator. By using a simulator the risk of damage to the heli is decreased in case something goes wrong mid-trick.

The process of flying upside down is started by rising the throttle on the helicopters so that it is just off the ground. Care should be taken not to raise it too much. The reason for this is that it is imperative to take time when learning this trick to avoid crashing the heli. Within time you possibly will start to feel how the helicopter is reacting to wind etc and you can react to these movements.

Very gently the throttle should be increased so that the heli moves off the ground. As the height increases it is important that the heli is kept as stable as possible. After a short time, the throttle should then be moved higher again. After every few feet, the pilot should stop and stabilize the helicopter.

Next, it is time to commence a loop by decreasing the angle of the helicopter and increasing its speed. As soon as it starts to dip increase the angle again so that it loops forward. The angle should then be moved to -2 once the pilot has reached the top of his arc.

The pilot is then required to add more cyclic as he is moving to the top of his dive and to slowly add negative collective as he is approaching the top of his loop. As soon as the helicopter is at the top of its loop its motion will be changed by the negative collective and the helicopter will be upside down.

Rotors are the blades of the heli. They are used to generate speed when the heli is moved at rapid speed. Normally, they spin in a way that produces downward force. For a helicopter to move upside down, these rotors should be spun in the opposite direction.

Helicopters that are able to reverse the rotors' thrust can also fly upside down. To perform this wonderful looking trick the elevation needs to be increased to a safe height and then the pilot quickly puts the rotors into reverse. This should be done while the helicopter is airborne. As a result of this, the heli will be momentarily suspended in free fall and the force of the rotors will spin it upside down. As soon as the helicopter goes upside down the throttle can be inceased and the thrust from the rotors will now be applied towards the ground, the helicopter will remain upside down and remain in the air.
