Aid needed for quadcopter
We've been building a quadcopter for the past 2–3 months and have worked through a lot of issues along the way. We're currently using Mission Planner, and our ESCs seem to be calibrated and working correctly.
Our current setup:
- Drone weight: ~1–1.5 kg
- Motors: A2212 1000KV
- Flight controller: Pixhawk
- Battery: 2700mAh LiPo, 7.4V (2S)
The main issue is that, even with a fully charged battery and full throttle, the drone can barely slide around the table and shows almost no sign of lifting off.
We're also having another issue where the propellers keep loosening on the motor shafts during operation.
At this point, we're wondering if the problem is with our power system, propeller setup, battery choice, or something else entirely.
Does anything in our setup immediately stand out as incorrect? Are these motors simply too underpowered for a 1–1.5 kg drone on a 2S battery, or should we be looking elsewhere? Any advice or troubleshooting steps would be greatly appreciated.
