An amazing 3D flight demo of the Marcel's SJM430, made by Ugo, a wellknown young and great french 3D heli pilot.
This SJM430 R/C heli has been tunned by my friend Marcel. New scorpion motor and ESC, homemade A/C belt and pinions, etc...
The most important : Flybarless ! with an AC3X for the stabilization.
A must see.
Special thanks to the helisolution.fr team for their kindness and advices. All of them are so incredible pilots !
