Drum roll please... final Neu motor choice(s)......
 

well, almost. I narrowed it down to 3 Neu's, with my heart sorta set on 1. The setup: Team Losi Muggy, MMM, with 6S 5000mah, and ?? for gearing. Goal: 60mph-ish speed + 30min-ish. runtime.

1)1515/1Y 2200kv - my 1st choice. Will hit 48,840rpm w/ 6S
2) 1515/2D 2050kv - 2nd, will hit 45,510 rpm
3) 1521/1.5D 1900kv - 3rd, will only hit 42180, but most importantly, I think this one will have TOO much torque for me; I've seen videos on youtube!

There is a vid on youtube of a guy with a 1515 2200kv, in an 8T truggy and 4S. I know it's much lower voltage, but even with this motor and only 4S, the truck STILL flips with no problem!! Then there's the guy who did the 1521 1577kv on 6S in a Muggy on youtube, and all it did was flip! With a 22T pinion! I want to be able to pop a wheelie, but not flip if I sneeze, ya know?

So, my 1st choice goes to 1515/1Y 2200kv, despite what others here have advised. Please speak now or forever hold your piece; but keep in mind I AM a dumb(!) noobie, so don't let me screw this up if you think I am. I must order by the 30th.

#3, if your gonna drop the cash why not? You can always use the awsome programming of the MMM to tone it down, then when you want more, turn it back up.

My two cents (and a splash of envy)

Go with the 1515 2d, 45k rpm is enough to do what you want. Not sure if you will get that kind of runtime geared that high though...

Just to clarify, if I punch the throttle on any of my conversions they flip over. You just have to learn some control...

I would go with 2) especially since you are after 30min+ run time

I would go with 1521/1.5D or you can even go with the 1521/1Y. The 1515/1Y and the 1515/2D will suck more AMPs than the 1521/1.5D. You will absolutely love the torque which will make the truck get up to speed much quicker. The 1521/1Y will have more torque then the 1521/1.5D and if you feel your speed is not enough, just try a bigger pinion. Right now I have my truck geared for around 35mph+ and I only see spikes of 75A.

I don't see the need of the 1521, I think the 1515 will suffice. I got a 2.5d/1515 (1700kv and on 5s its freakishly strong, I'm hoping to try it on 6s with a MMM soon. Don't got the money right now, but soon

The Muggy is a big truck. The 1515 is plenty, but to get the most run time, the 1521 mentioned will need less AMPs and will help a bit.

2.5d/1515 1700kv would be my choice for run time and torque

Dont forget theres more than just how fast the motor is turning..... with the 1515/1y with 6s setup you will have increased stress on your drivetrain, escpecially the diffs, and getting that power to be usable...wheelies will get old fast, you can gear up to help with that, I have put some extra weight in the nose to help with wheelies,

Does the muggy use a center diff or a tranny?

1515/2.5D is a killer motor on 6s. PLENTY powerful for that application. Running higher kv doesnt necessarily give more speed. Speed is in the gearing.

All of those motors you mentioned will pull alot of amps on 6s. 60+ MPH and 30+ min runtime will be a hard combo to get with that big of a truck and 5000mah. With the 2.5D you can gear it up for the crazy speed, but then gear it down and get nice long runtimes as well.

Just my opinion.

I'm with jhautz on his suggestions. The gearing is where you need to be focussed as well as how that will be impacted by your KV. KV doesn't equal speed unless it's geared that way. And if it is - you'll be burning more amps at that speed than with a lower KV motor geared to the same speed. If you want run times, then a lower KV is best.

If I were you, I would get the 1515 in the 1900KV for full flexability. Besides, I have a link here for you where they're selling one for under $200 - new. This is what I would get if I were you:

Any of those motors will do about what you want with the right gearing so I say why not save the $$?

That motor flydma is selling is not for just the motor. He'll need to buy the gearbox too and that will add $110 to the good price of just the motor.

I'm pretty sure he can just get the motor w/o the gearbox. I could be wrong though. I got my current 1515 from them also and just avoided the gearbox option. Might be worth a call to them to clarify if he's interested. Sweet deal at $188 if it comes w/o the gearbox. Good catch though lutach.

I tried getting that motor, but once you add it to your cart the gearbox is added automatic.
