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 .
