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>
