Hi everyone, I'm in need of a bit of help finding an appropriate esc for a non-extortionate price. I am designing a heavy lift drone that is based around a lot of the architecture used by 700 series helicopters.

I need:

• Input Voltage: Must take 12s (50V)
• Current: 130A to 160A continuous minimum.
• Helicopter Support: Must explicitly list a Heli Governor Mode in its features so it doesn't strip my gears on startup.
• A built in BEC for my servos etc
• be able to work with Ardupilot mission planner. (I assume they would all work but let me know if thats not the case)

I really do not know a lot about helicopter electronics, so if I can add an external BEC easily or cheaply, please tell me and give ANY ADVICE YOU CAN. I'm pretty sure that an external BEC is going to be the way forward to save on £££, but if I can find an integrated BEC then that is preferred, as it saves precious weight.

cheers for any engagement))
