World’s first ROCKET-DRIVEN helicopter: EXTREMELY FAST !!!

First ROCKET-DRIVEN 700-size helicopter. 20 individual booster elements deliver 8 kg thrust and send the model vertically into the sky with insane acceleration. Biggest challenge was the remote-controlled ignition because all single engines had to ignite absolutely simultaneously and reliably also in the high-vibration environment of a nitro helicopter. Heli is a Vision-X by Helisystem AG, weight with rockets about 6.5 kg. HeliGraphix LEGACY is our new series bringing back old favourites in HD resolutio
