Opto ESC with HKpilot Mega 2.7 JP1 jumper

Posted by Rusty Sprocket on April 27, 2016 at 12:24pm

Hello, I had an unfortunate crash with my fixed wing (Skywalker X5) and ended up frying both my motor and ESC. So I ordered a new motor and ESC from online store. The package arrived today but the problem is they sent the wrong ESC. I ordered a 30A ESC with built in BEC instead they sent a 30A Opto ESC. It will take long time to get the correct ESC from them if I send back the wrong ESC that they delivered to me today. So the question is, can I use the opto ESC with my HKpilot mega 2.7 if i put the JP1 jumper on? Or I still need to add external BEC? I power up my board with HKpilot power module by the way.

Thank you.

    Get yourself a Castle ccBEC ($20) and you can program a clean 5V to the rail. This is how I do it with an APM setup and I'd imagine its universal. I've been there too, had a 1880 go nosefirst into the dirt at 50+mph... It happens! Good luck!

      Thank you for the suggestion! I'll check for it!

    The power module does not deliver enough amperage to run your servos and could brown out the computer.  If your ESC does not have a built in BEC, you will need an external one.

      Thank you for the explanation! Guess i need to hold my flying for now. Going to contact the store for replacement.
