I have been building my first quad, and when I have gone to test it, it flips on takeoff.
I have the below specs:
4 x DYS 2830-14 750kv
4 x 14x4.7 props (cw & ccw)
Hobbypower simonk 30a esc w/ bec 490mhz
Turnigy 30-40c 1000mah 4.s (testing battery)
frsky x8r reciever
taranis plus transmitter
I have gone through the calibrations settings on openpilot, checked the neutral points, however when I apply power, it flips on take off.
I have checked the following:
- Checked and double checked motor spin in right direction.
- Checked props are on the right motors.
- Checked the orientation of the cc3d controller.
- Checked the gyro was level on the surface.
I have been on youtube and found the above tips, but it still occurs...
I have also found one of my motors seems to lag behind, so I replaced it.
I am fresh out of ideas... any help is appreciated.
I am taking some apart now that have little balls of solder in them, think it got in as some solder can become airborn, but I'm sure that is what these would sound like as the solder caught in the motors.
