Are you sure you are running your packs in series? That would be 8S a high voltage setup. Typically requiring a high voltage ESC.

He probably meant parallel.

I think so as well. Just need to put it out there so someone new to all this doesn't give it a try and melts down new equipment and possibly injures someone. Reading here in the forum I think it has happened before.

OOPS, MY BAD , sorry guys. Kevin's right, its a 4s parallel setup.
The ESC & packs were cool, but the mill was a bit warm, I think the h2o pick up in the ride pad had a blockage.

I plugged the pick up & hung a cf tube pick up on the strut. Now I am waiting for the 200A mystery esc I ordered. I may try this setup on a Venom 5000mah 25c 5s1p x2 parallel setup just to see how it does ....

Mystery esc? It's a mystery if it's going to work or not? Had to...lol

Have you run them before and any luck?

Wise arse

I ordered the 200A mystery ESC Sun. DHL already has it & its in transit from HK.

Its a new suppo ESC,not one of the clones that use old discontinued parts.
We have all run suppo esc's off & on. I have had good luck with several suppo's, just don't push them to to their max or they'll burn.

I bet that 100A reversible would be great with a retrieval boat

So far so good using two 200A Thunderjet ESC in my 41" Sprint Cat twin setup. I would bet $$$ they are the same ESC as the Mystery with different color shrink and label. But we may never know, it's a mystery.

Nice . You mean turbojet ESC ?.

Turbojet used to be a rebranded turnigyseaking, idk who makes them now. According to the specs, the bec on the turbojet is 1A higher.

[78MaicoRider]

Oops yep that's the one. Sorry, I am wrong. Glad I didn't wager! Anyway the Turbojet seems to be working fine for me. In a 41" Sprint Cat I'm using two 200A to feed FC 3730 1600kv 6S power. Also use the 200A in 32" Apparition with a FC 3740 2000kv on 5S. This boat really flies and my fastest so far! And I converted a Graupner "Systems" boat to brushless with a 150A Turbojet and DYNM 3830 1800kv 4S. This boat lower half is a 41" Sprint Cat reduced to 29". All working good. I have a Hobby Wing T180 and Leo 4082 1800kv for the 29" Sprint Cat. The latest boat is going to be a step up in all respects. So that my penny's worth

Thank you all for your help and info. I have ordered a blue Mean Machine bare hull from OSE and am now waiting for it to show up as the blue is a special order. I have read many build posts and understand that the tried and true combination is the Leopard 4074 or 82, Seaking 180 ESC, M445 prop, 4S2P combo good for around 50 ish mph.

This sounds reasonable, but I feel would be slower than my current UL-1 setup I have gotten used to driving and want something faster. UL-1 is Leopard 3674, Etti 150, X642 prop (de-tongued), 4S2P 3200 Mah each.

The reason I want to build the MM is for more run time as I can fit larger batteries and run in rougher water as it is not a hydro.

OK, so there is the history and now the questions

Before I purchase all of the rigging I would like to know if anyone has successfully run Neu 15151y 2200 KV on 5S2P? I am looking at doing 60 ish and do not mind spending the extra on the motor over the Leopard. From what I read the Leopard would be short lived on 5S and read in 1 post the Neu would handle it.

If the Nue would be OK on 5S would a smaller prop than the M445 be needed?

Appreciate the help as I do not want to go through wasting money blowing up things, especially an expensive motor like the Neu

I would start with M440 on 5s with the Nue1515 1y.

I just got the new setup on my meanie' tied up last night with a long rudder so she'll quit spinning out & handle better. I took it out Saturday and ran it with the 3674 2350kv mill, 200A ESC & the m445 on a 5000mah 5s and it was smokin' fast. Unfortunately it was spinout happy and pretty much uncontrollable because the rudder was to short.

Other than that the setup was great balanced at 30% & the strut level with the sponsons. Now the marine specialties blade I hung on it sits 2 15/16" below the sponsons. Now she should stay stuck to the water .....

BTW, the boat is sitting on the stand & the rudder is even with the floor.....

post a vid!

You know I will bro. Heres the video from saturday, too bad I had radio range issues cause it was crazy fast & out of control.

With a neu or castle 1515 1y on 5s, and properly set up with t-180 on m440 you should see low 50's - on x642 cut to m642 you should see about 60. M445 I didn't get a GPS but it was damn fast, and a bit more squirrelly
