Hi guys,
I am relatively new to the world of quadcopters and I have never flown one either. I just finished building my first quad. I decided to go with a combination of X580 frame and KK2.1 board (v1.6 firmware) from Hobby king. My motors are 800Kv supplied by Turnigy plush 25 amp ESC's. The whole apparatus is powered by a 2700 mah 4s battery.
I am using 11" x 4.5 props. The final weight of the quad came out to be 1282 grams.
I am having no luck in getting this apparatus up in the air. All calculators suggest that it should fly just fine. I have double checked my motor layout, prop mounting, rotations, and everything else I can think off.
Here is my motor layout based on the picture below:
Top left: M1, turning CW
Top right: M2 turning CCW
bottom right: M3 turning CW
bottom left : M4 turning CCW
At about 30% - 40% throttle, the quad tends to just 'roll over' along its center axis but never leaves the ground. I mean, M1 and M4 lift up but M2 and M3 just sink into the ground.
All Esc are programmed the same way. All motors start up at the same time and seem to running just fine. What is it that I need to be looking at next? Is it the KK board? do I need to adjust my roll/pitch as I increase the throttle?
Any suggestions on how to troubleshoot this problem? Things to double check?
Thanks
