Getting enough thrust is simply a matter of applying enough money.Of course ,being able to control the amount of thrust from each motor is the only way I know of to have control of the "pitch axis"! This means----2 throttles!But how will you control the "ROLL & YAW"axis as the model ascends???Can you say--"THRUSTERS".Extremely complex and costly!Simply put, none of the control surfaces have any effect at all as the model has no flow over them on take-off!!!It would be like a heli with no tail rotor and no angle control on the main output shaft.However,with enough time,money,and help from knowledgeable people,I'm sure you could succeed>
you seem to missunderstand me
: I dont need pitch control nor roll or yaw while hovering so i dont have to get 2 independent throttels , see what i mean .. just one throttle of the both motors and.
The planned
Lift Off according to my painting and position of the ducted fans
1.starting by having the plane on earth
2.pointing the both motors dwonwards( two identical servos controlled by one stick on the transmitter)
3.starting the motors and accend till its lift
