Hi All,This is my first post, I have been a long time reader and you guys have saved me a few times in the past.I have built a quad and it won't take off. The rotors all turn the correct direction and it responds corectly to me moving it and also to me using the radio to control it. It just seems like it is too heavy.The build is as follows:Apm 2.6Angel a2212-13 980kv brushless motorsSimon 30a escTurnigy 2 cell 7.4v 2200mah 20-30c discharge battery.3dr power distribution board.3dr power module.3dr gps compass9*4.7 carbon fiber props.The frame is fully carbon fiber.Total weight about 3lbsHave I made a wrong choice with my hardware or should I be able to fly?If it should fly what could I check next?Thanks in advance.T
On the page for the motor, they have it specced at 720g/motor max it looks like on 3S battery using your prop. That would give you roughly 6.3 lb max thrust quad, which would be good. The rule of thumb is you want your weight to be under half the max thrust. Unfortunately using a 2S battery, the motor is specced to 360g, which is about 3.1 lb quad thrust. Unfortunately not enough to lift your quad. But the fix is easy, buy a 3S battery!

Thanks very much that's an easy fix. I really appreciate the help. I'll order a battery now.
