thank's for trying to help me RedGN ...
as i said before .. i'm a real newbie .. so i don't know exactly what you want to know
VTOL is short for vertical takeoff and landing .. kinda like a helicopter but with a different body shape ...
our budget is around 500$ .. but ofcourse .. the less expensive .. the better
we need the remote control to be able to control the speeds of the all the motors simultaneously and individually
waiting for your answer ...
