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

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

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.

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.

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

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.

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

So far all I can say is its rated high current high voltage.. I will put that to the test on the work bench long before it gets near an EDF! programming options very limited.. but hey it was cheap for 150Abut its a chunk coming in at 7.52 ounces.. QUITE HEAVY!! and large, going to be hard to mount in a slim aircraft. so far not impressed. I will update if it gets better or worse, going to see if this will run a dynamax 127mm fan with a HET5068 675kv..
