Flycolor FlyDragon 150A ESC 5-12S HV OPTO for RC Hobby Model Aircraft Helicopter Electronic Speed controll for 105 / 120mm JP EDF Motor

When I finally decided having 150 amp worth of control was way cool was when I decided I really need to run a 10s setup. This ESC is large and solid, if that is any metric.

Works great with JP 105 MM Fan. Already has perimeters set for JP unit.

The esc works but difficult to use and not much instruction on calibration.

So they charge you another $50 or whatever, for an internal BEC... which literally equates to a 3rd 26 GA wire being soldered to the 5v output of the exact same board. I'm not an electrical wizard, but I've built 6 quad drones from scratch, following step by step directions. I was having a hell of a time working on this, my first stand-alone ESC, so I said F it and cracked'er open. If anyone with actual electrical knowledge/intelligence can elaborate on what they see here, it would be greatly appreciated/helpful to both others and myself! DO NOT reverse throttle on signal wires!... that's probably elementary for most folks, but I had to find out the hard way = making a smoky sparkler. TBD.

Does what it's supposed to.

I don’t have an immediate application for a 150A ESC at the moment, probably it will be an EDF. But it’s nice to have an ESC on hand that can handle it.

lol I have used these in many large jets without issue , today one let go brand new on a maiden L-39 105 set timing to 15 , boots she exploded and caught on fire, it happens I still think the value is there and things happen

PERFECT FOR WHAT I NEEDED. GREAT QUALITY. BETTER THAN EXPECTED.

Yet now tested with DIY water chiller compressor on low current 4A, using ESP32 as controller.
