Beeps at video end simply means the board is not powered correctly and there is no valid output signal provided to the Escs.

Is the board powered (do you see led blinking / board booting) using battery power source ?
The board should be powered using +5V from Esc's bec or additional ubec.

I have been able to get it to fly, but I have to fiddle with the throttle (moving it very slightly up from bottom) and then it will beep three times and then one short beep and then will arm just fine.

The board is powered via a 5v solder pad built into my PDB, no power from the escs.

Maybe the min values are not correct and cannot allow Esc init at start.

Try setting the first two output banks from PWMSync to PWM-490Hz, save.
Disconnect all and see if he issue still.

[fox]

I set them both to 490Hz PWM, same issue still

Reduce refresh rate
Redo Esc calibration.

changed them all to 50hz pwm, and recalibrated all the escs following that tutorial exactly. still the same issue.

It's so strange because I can sometimes get it to arm if I move the throttle up very slightly, and in that case it does the 3 beeps, then one short beep and arms / works / flies just fine.

Looks like Esc crap.

Try setting the min value same as neutral or some other value that allow Esc init after you power using the battery.

[fox]

pardon? esc init?

[fox]

?

[f5soh]

Esc init = Esc initialization

If not initialized Esc output continuous beeps.

[fox]

Where is that in the program?
