Hello,
This is my first time building a quad. Even trying from last 2 months, we were unable to make even our first flight. We went through many websites for troubleshooting our problem. But unable to find it out.
Specifications of parts used:
Turnigy 11.1Volts 2200 mAh battery,
HW30A ESCs (30amps) 4 in number,
1100 KV BLDC motors, 4 in number,
KK2 Flight Control Board,
6 channel transmitter and Reciever model number FSCT6B,
10 x 4.5 propellers CW and CCW 2 sets.
We have done a factory reset to the KK2 board and loaded the values as per following website

Arming is possible. But the problem is when I arm a motor and start to give throttle, the motor is rotating for a while, When I gradually increase the throttle , the motor just stops rotating. This is the case with propeller. But if I take off the propeller and give throttle, even at maximum throttle on transmitter, the motor keeps on rotating. As soon as i attach propeller, the motor starts rotating and when i gradually increase the throttle, it stops automatically after a while. And if I attach two motors with out propellers, they sometimes are rotating at high throttle and at times, one of the motors will stop rotating after a while and other keeps on rotating till high throttle. Same happens when I add up the four motors. And with propellers, even one motor is not doing till max throttle. What I understood is, motors are not getting enough power from the battery. But the case is same even when we did replace the battery. I was thinking that the props are two large and hence the motors are not making till high throttle. But on verifying in different websites, i concluded that this is not a much of problem. There are people who made their quads with 10x4.5 props on 1100KV BLDC. Hope i am not wrong.
Now I am unable to figure out what actually the problem is. Can anyone help me as soon as possible please. Thank you..!
