Hello! I just started building this quad and need some help getting it in the air.
I tried to hover and the motors started to pulse and wouldn't come off the ground. So I thought I'd reprogram the escs. When I did (doing so 1at a time with tx) and everything was set back up, I plugged in the battery and the motors started beeping non stop.
Please help! If you have any ideas I would love to hear them.
From the esc manual the beeps are a warning that my throttle input is not all the way down. But it was functioning before the reprogramming...

ok so i got those issues fixed and have loaded a sketch as well as used the gui to calibrate the sensors. My next question is what are some good settings to play with on the gui to see this thing have a smooth movement? As it stands now it will hover but has very jerky movement. Anyone out there have any suggestions?
