The idea of the Rescue Cup
Flying a Koax-Helicopter is great fun. But most experienced helicopter pilots consider koax helicopters as toys. These pilots will maybe change their mind when the try to fly special missions. That’s why we invented the koax rescue-cup!

The rescue-cup consists of a special scenario that brings great fun. It is designed for standard koax helicopters and can be flown by every experienced pilot. The pilot has to fulfill severall rescue missions that are more or less transformed from the reality. The rescue missions rerquire the perfect control of your koax helicopter and are as follows: extinction of a burning skyscraper, rescueing of injured people out of the building and transportation to hospital.
The main intention of the rescue cup is to have fun with a simple koax helicopter by creating new challenges of flying. No matter if you want to do a competition with other pilots or just fly on your own it is big fun to improve one’s flight skills.

The components
The heart of the rescue -cup is the rescue unit which is mounted easily on your koax helicopter. With the unit your koax helicopter is completed with 5 special rescue functions:

- extinction left rubber bands
- extinction right rubber bands
- launch a rescue splint (changes extinction function to rescue function)
- roping of a rescuer
- dropping of the rescuer

The procedure of the rescue-cup
The missions take place on a special designed tower (skyscraper) with 4 down turnable fire cards in the windows. For a succesful extinction these cards have to be hitten and turned down with rubber bands that are launched from the rescue unit on the helicopter.
The roof of the tower is formed as a helicopter landing platform that one of the victims has reached so that he can be saved from the roof with the helicopter.
Half of the tower roof is open so that a quadratic hole of about 20×20cm results, where in another wooden victim is waiting for being rescued. A special rescuer can be let down on a rope from the helicopter to save the victim with a comand of your radio control.

Every mission starts and ends at the SAR base where the rescuer is taken on board an the helicopter is refueled after mission.

As soon as the rescue pilot has put the rescue unit on the helicopter, the games begin. The pilot has to fly his helicopter to the tower and hoover in about 70 cm distance exactly in front of a burning window. Now the pilot tries to turn down the fire cards by hitting them with the 2 rubber bands shooten from the unit. The goal is to hoover very precisely when pressing the extinction button on the Radio control. The challenge is to stay exactly in fromt of the window while you are fine tuning your position because every change of one flight axis results in a change of another flight axis. Once you are horizontally an verticallly in a perfect postion you finally have to gear the whole helicopter to get a perfect shooting angle. When launching the rubber gum with the RC you have to be carefull not to snatch your hard reached position. Really not easy!

Once both fire extinction rubber bands are launched, a dramatic rescue operation starts. For this time the rescuer has to be let down on a rope by putting the switch on RC and. It is a real exciting moment that comes very close to reality when the rescuer jumps of the helicopter! But the most difficult part is to lead in the rescuer in the opening of the tower roof while hoovering the helicopter about 1m over the tower to save the person inside the tower roof. Beginners often wonder how difficult it can be to lead the rescuer in the opening with the strongly oscillating rescuer. Every little movement of the helicopter can make the rescuer more oscillating. Nevertheless it is very important for this mission to watch the helicopter carefully because it can easily come down to low and hit the tower with the rotors or any other part.

When the pilot finally lead the rescuer in the opening of the tower roof he has to decrease very carefully the throttle to bring down the helicopter about 20cm to pick up the injured person with a magnetic “click”. Don’t fail now, climb higher (exactly vertically and very slowly) to save the 2 people hanging on your helicopter rope.

As soon as you have reached a safe altitude, the two people are hanging quite stable on the rope you can start the flight to the hospital.

The rescuer and victim set has to be put down exactly in the hospital box. Because of the oscillating rope this is a simular difficult task to the one before but now the pilot has to push the eject button at the right moment to put down the people as smooth as possible.
