RADICALL v.4 : Video Presentation of final version

Razeebuss Radicall v.4 is now on his final version ; this V.4 version was upgraded with 2 mains improvements :

1 – A brand new virtual cage specially develop for the Radicall

2- An automatic thrust angle control system

Virtual cage and Thrust angle system are link together to detect flight or take off status , and control unit position in all situation .

For take off the system will hold propeller shaft to horizontal axis , balancing in real-time all pilot movements  and optimizing thrust angle .

In flight and specially during pilot’s harness and speed bag installation the system will be adjusting the thrust angle to optimized position without any action needed from the pilot .

Below a ground video demonstration of the system running .



Razeebuss Radicall : Last Virtual Cage flight test

A short video of our last virtual Cage testing .

This flight was done in thermal condition to check new cage parameter , taking  off from a flat field with irregular ahead wind 15 to 20 Km/H .


Virtual Cage system is a king of Gyroscope controlling unit position in 3D . If any off one of the maximum preset value on one of the 3 axis is reach , the system is stopping immediately the E-drive .

Superb demo flight for Clement Latour & the Radicall
