Neu and Mamba Max Combo

[jhautz]

The 1940/7 is a wicked motor. You will love it. And yes the RCM heatsink will fit it.

Try the 1940/7 on 5s if you really want a kick in the pants. Its jaw dropping.:p

[Sower]

What vehicle are we talking about here? Monster truck, truggy, buggy . . . ?

OK, here I go second guessing myself again. If I get a performance increase with the Lehner, should I go with the 1940/7 or will the 1940/8 have performance similar to the 7XL?

[glassdoctor]

I would say 1940/8. After what you saw with the 7xl... saying it's almost too much, etc... do you want to go with the same kv again in the 1940?

Now is your chance to drop the kv a bit...

7:2239kv
8:1959kv

The 1940/7 is very close to your 7XL.

I don't know how much the actual performance will be different going to a 1940... should be about the same, just more efficient.

Just more food for thought. I'm joining this thread a little late but thought I would throw my experience with the MM and Neu 1515 1Y combo in an LST2. I've been running this setup for about 5 months now without any major issues. What I once thought was cogging was actually my brakes binding and causing stuttering. Believe me when I say this truck has been run hard and has had it's share of nasty crashes. The MM has even been ejected and dragged by it's wires a couple times. The only issue I had has been posted here and has to do with LVC settings on 5S. This video clip is pretty typical performace. on 5S. I couldn't be happier with my setup. Would I recommend it? Not without mentioning issues others have had here. With that being said I will be doing a CRT conversion soon myself... MM/Neu

I think you guys should check with Mike. I called him up and told him I already have the MM for my E-Revo and asked what motor he suggested and HE recommended the Nue 1515 2.5 and that is what CC was recommending as well - according to Mike. Reading this makes me a tad nervous since I have not finished my project but have a nice $280 motor sitting there on my bench waiting for a few more parts to complete the project.... fingers crossed!

There seems to be conflicting info coming from CC. When the MM was first out Shawn was recomending the Neu. Now it depends on who at CC you talk to... some don't seem to know there is an issue, and others act like it's common knowledge.

It seems to me that the recomendation of hte Neu is based on how good the motors are, without actual experience running them in cars.

I'm sure the Neus are great in the planes... but remember the car thing is relatively new to CC... they are still what I would call plane guys.

Edti:
But, they are slowly coming around... and the Mambas are becoming a larger % of their business every day. A couple years back they were 100% planes... now it's more of an even split. If they play their cards right, the company could be car dominated in the future.

OK, I have to quit thinking about this for a while. I'm changing my mind like my wife does. We finished my buddy's buggy tonight. Well just about. We got the battery tray figured out and we're hoping that his MM and 8XL show up tomorrow. After running the 8XL, I'll see if that's the route that I want to take, speed wise.

I was getting ready to pull the trigger on the Lehner, but then I remembered the 4mm shaft.

I may just order the Neu and just live with what I get. If it cogs too badly, I'll just put it aside and wait for Castle to do what they have been promising to do. I'm still liking the 1515/1Y, and that's only because it's the only motor they offer that is in the ballpark kv that I want to be in.

Oh, I don't know if I got the answer to this, but will the RC Monster sink fit the Neu smooth can motor? Does it even need a heat sink? If I get the finned model, will I need a fan? I'm just asking because, if I need a fan, I'd just as soon use the RCM heatsink that I've already attached a fan to.

[jollyjumper]

no, it will not fit, the smooth nue is ~39mm while the heatsink/clamp is made for the "normal" 35.8mm motors.

One other thing to consider is that batteries also seem to make a difference in the cogging with the MM/Neu combo. I have an older Kokam 4s 3200 mah pack that seems to make the system cog a lot more than newer Lipo packs that are coming out now.

The MM is a great little system but, I think I'm with jhautz, I like the Quark for the 1/8 scale stuff right now. That may change though. Hopefully sooner rather than later if CC can do a programming fix.

[Sower]

Let's see if I can change my decision again. Here's the question:

If the MM runs great on a 4 cell, can you get enough power from a larger mah 4 cell and run it with a Lehner 1950 on a truggy? Rather than having to go 5 cell. I know the 4 is great for a buggy, but since the truggy is bigger I wasn't sure.

What do you guys think?:eek:

[jollyjumper]

you only need 30~35 mph in truggies so you should be good with 4cells.

Ah, the key word there is "need". I know I only "need" 30-35 mph, but I would like 40-45 mph to be attainable . . . with the right gearing.:005:

So . . . does a larger mah give me that option?

[jollyjumper]

i see, you want it to be fast.
i dont know then.
