Mystic 1850mm/twin Lehner 3080 setup, need advice?

[Yamadori]

Hi guys.

Please help me and give me some advice.

I will be putting together Mystic 1850mm MHZ carbon/kevlar bulletproof hull with 2x Lehner 3080/8.
That's what I already have. So this is my starting point.

I am a bit confused with choosing esc. I plan to run the boat with 2x 12S...I would use two 12s 5000mah parallel for each motor to reach some reasonable run times.

Lehner proposed: MGM TMM 40063-3 X-SERIES. Should I go with that?

I don't have that much experience to be able to choose wisely, so I'm asking you to check my setup ideas and suggest me possible better solutions. I will be more peacefull if you tell me this is ok.

Thank you for all your help and effort.

I know you are probably sick of giving advices to less experience people on the forum..but, I would really need some input. I came here to learn..but I cannot learn anything if nobody wants to teach me...
So please...can anybody tell me anything about those hi Amp controllers and if there is some more choices.
Thank you in advance

i don't think this is an issue of people not wanting to help its they don't know how to. very very few of us have built boats of that size with that kind of power the big 2,000$ escs are purely fiction to most of us.

i know someone with smaller mgm controllers they're fantastic but can't comment on the bigger ones. i don't want to give advice or such a huge purchase.

schulze 40.300 have been used with lehner 3080 8 wind motors 12s2p. i have posted a link to hpr 233s using the 3080 motors i'd probably try to reach out to a few of the owners too. boats like this are far and beyond the world of typical FE.

Iridebikes247,
Thank you very much...I appreciate your good will to help me...and you already did..just by taking the trouble to answer my problem.
Thanks, I will check the link.

Concearning the cost...exactly that. I'm not so sure in esc choice so I'm asking. I will not be very happy to buy 2000$ escs just to find that wasn't a good choice :)
Thanks
All new suggestions welcome with much gratitude...

Look on youtube...plenty of those boats out there with all the specs on what they're running. You can ask them for guidance.

[Yamadori]

Yes, I did...and I will surely, but still..I highly value opinion and experience of people on OSE forums.
Thnx

Hi, I'm with Mike on the idea that not lot of us have build those big boats so it's very hard to give a direct answer. But based on bigger boats and their setup, you have a few power options I believe. For a 185 I would go with LMT 3060's rather that the bigger guys. The old school Schulze can still power those, so can most solid 300A capable ESC's I believe. As for your 3080's you may have a bigger motor than what you really need. I think you would benefit more with something RPM capable rater than torque. But since you already have them, there are still options out there. I honestly don't think you can go wrong with the MGM's, I wonder what Martin at MGM will recommend for those? "Most likely what you are already looking at" if $$$ is not an issue, talk to Martin at MGM and let him guide you. That way you get the right setup, and most important the right settings and options for the controllers. As the saying goes..."pay now, or pay later"

I use a couple smaller MGM compro escs and they are a great little known controller they make a 250 hv model also . They have good warranty work and reasonably.priced out of warranty work

I also don't own anything that big, but I do have a 25063 and love it. It did double duty a couple weeks ago in a 45" hydro with a 3080/8 on 10s and a 44" cat with a 3060/10 on 10s and performed extremely well. One heat a water line came off and temps went up 10 degrees above being cooled. They're definitely pricey but worth it. I haven't owned a schulze, but I will own another MGM.

Yamadori,

I have a lot of experience with the MGM controllers from the smaller 28026 to a large 40063 and even bigger ones for commercial use. These are excellent controllers and in my opinion are of benchmark quality for hobby applications. I have tested your exact combo although I used 10S instead of 12S. I would also recommend the 40063. Compared to even the 3060 and smaller 3040, the 3080's are capable of drawing huge amounts of current. On 12S the 3080/8 will pull 260A without a sweat and easily double that if you over prop the boat so you want to err on the overkill side for the controller.

The hardware quality is very high on these units and they are constructed well. I have several recommendations to give you the best combo. Add these options to your base level MGM when ordering.

WP version: this adds water protection, but still allows servicing if necessary (I do not recommend the water proof version as repair is not possible due to potting compound)
Design with water cooled heatsinks: Somewhat obvious.
Double 10mm^2 power conductors on inputs: Although this is not listed, it is available.
Double 10mm^2 power conductors on outputs; Again this is not listed, but it is available. Assuming you are running in Delta, the double wires for each phase make connection easy to the motor.
USBCOM4: USB adapter to allow online programming.
CC_11 cable: Cable to connect USBCOM4 to ESC.

I would recommend emailing Martin at MGM ( [email protected] )to place the order and mention your exact set-up. He is very helpful and will know what you need. You can also ask him when the next time MGM will have the 15% off sale which is nice for 1000 Euro orders!

Any more questions feel free to PM or post.

Now you're talking guys...a big thanks to all of you for taking the trouble to think about my dillemas..
I apreciate it :)
RaceMechaniX,
Well, that was detailed really...almost as I' ve ordered a scientific study :)
That s very helpful...you have done everything I needed...told me mgm's are good, advised me what to be careful about, gave me a contact to ask Martin in MGM, and offered further your help...what can I ask more :)
Perfect. I will surely follow your suggestions...maybe even be free to contact you pm if I stuck somewhere.
Thanks people to all of you. I will post building process as I start after I receive all my parts
Of course...further input welcome
Thanks to all of you

I don't know how much your boat weighs compared to HPR 135, but this setup will get you 128mph: Everything listed is x2:
LMT 3040/09
Schulze 40.160WK
10s PQ XF 4400 45c
Octura X460

Yamadori,

If you have further questions just send me a PM. I will be happy to help you out.

My intention is not to offend you, but posting stuff like that and giving recommendations for an almost $10K build with obviously no real knowledge about the topic is actually pretty dangerous.
