If your AUW is 3.5 lbs then you will need a minimum of .5 to 1 thrust to weight ratio (just a wild guess) to fly effectively which means you will need 1.75 pounds or 28oz of thrust total or 14 ounces from each fan. The GWS 75 5 blade with a speed 400 motor will get you around 9 ounces. You can of course pump more power into the fan but you risk cratering it. I would suggest asking the EDF forum how much power in watts you can safely push that fan with. You may have to go to a weomtec mini fan and a brushless motor to get the thrust levels you seek. Anyway, I am loving what you're doing keep it up!
