MGM esc programming problem

Doug check the threads that I started, there is one I put up when I had an issue with a 1527 1500kv and an mgm28026 controller, there should be a video of what happened. I would do it for you but I’m struggling to do it on my mobile phone

I plan on testing the YEP 180HV and a Kosmik 200HV with cooling for potential HV controllers in my boats in 2018.

I have tried a set of YEP 180HV on a twin and will never use them again.

This one?

Care to elaborate Randy? What motors did you run? I would prefer to save a nice hull from a smelly mess if I can avoid it.

I use ducted fans as load dyno's for testing combinations. The smaller one is a Schueleber DS-86-HDS ducted fan mounted on some plywood. Allows me to load the motor at decent RPM's for extended periods to see if controllers have any issues. I ran the YEP and a 2250 for 4 and a half minutes at about 75% and everything was only warm. DC amp draw was around 125A.

The larger one is a 160mm I think and uses a Lehner 30 series motor which provides plenty of load not to mention tornado level wind speeds in my shop.

So just to theorize.. I put a 280 on my limited mono today.. it didn’t cut off.. but when I pulled the data said it was pulling 395 amps.. come on!!

That's phase current, not DC current. It's also the peak value of the AC wave form I believe. So 395Apeak =279Arms.
What was the DC current?

Yes fluid that is correct.

Hear is the thread of the build. I still have the ESC. they look fine. Actually I was drawn to them becuse of the size of the fets. they look a lot like a Schultz I had big hopes for the Yep 180.

So how to you work the math when you read the phase current top get dc current? I am spiking 900 amps some times with my 4S setups and it was hard for me to belive. That setup is a Neu 1530 .5Y, MGM 400-63, 4S3P 3300maH cells 65C/130C, ABC 1814, 11 pound 34 inch sport hydro. This hydro runs around 67MPH to 70MPH. I onlu have problem on the launch getting up to speed once it is at full speed it is OK from there on.

This is the boat. I have ran the same esc in this boat for going on three seasons. The only better ESC IMO is the 40.160

I have forgotten the Yep were 120 not 180 I just read that.

Randy. I am running a Dual 300 Flyer in a Twin Cat. Plett Motors. The Big 370BM/40/A1/S..X457 props. All good so far.

Thanks Howard I do not get around much any more. I have great memories of racing you years ago. I am glad I went to every race I ever did. (good and bad) I am not familiar with the Plett brushless motor do you have any comparison pictures?

It is good to hear about the Filer ESC, I have seen them work and then stop . I have never owned one.

I was running too with a singe 300A Flyer. It was good until 12s. Then the capacitors leads burned.But that was a bit overloaded.....
But before we burned 5-6 pcs. 250-400A Flyer. The Flyer contact Cathy very helpful and she provided me some spare parts free for repair.

10s Motor. Ran these in our 1/8 scales.
