does anyone use really big batteries?

[lutach]

I have the 1521/1Y in my BPP truggy and it's insane with 6S and even 5S. Arct1k saw a little run with 10S lipos. If my truck was geared right, it would've been awesome.

Personally, my pack suits my needs so I'm not going to come in here and try to defend them and have this guy spend 550!!!???!! on their battery. Obviously, if you guys can get away with running 1p, then them trying to sell a 2p battery says something about them. Especially when its such a high capacity and they still want to go 2p.

Maxamps lipos have their place, mainly 10th scale 2wd. About the only thing they sell that will work in a MT is the 8000 packs. They get rather heavy, and large, especially over 4s. I had alot of issues with defective cells, 10-12 packs... That alone would steer me away from MA, not to mention the outrageous prices, and"questionable" specs.

A 6s lipo may be too much for the 1515 1y, go with a 1521 motor, 1800-2000kv for 6s...

Yeah, I have one that works great. But like I said, I'm 10th scale 5lbs, not a big ass 8th conversion.

Not sure if your serious or not but if so there is more to speed then high motor RPMs's. If that was all that mattered then you could just throw in a mamba 7700 and go even faster right?

1521's create more power and can be geared higher then is possible with the 1515 series motors. But if you really want the high rpms you could get the 1521 1D. More power then you'll be able to use, high rpm's, and certain to pull a ton of current in the process.

[ReV:-O]

but i figured the 1515/1y was a pretty strong motor regardless and could handle the muggy? i dont want to buy a really powerful motor and then just continually strip gears n stuff

[mxracer]

1y is nice on 5s !

flight power packs have been flawless too

flightpower all the way !

[ReV:-O]

oh oh i think i found the solution:
EITHER:
a Neu 1521/1D 2900kv on 5s running at 53650RPM,
or
a Neu 1521/1.5D 1900kv on 6s running at 42180RPM.

Both of these are the 1521 motor, and so are stronger than the 1515. with the first option, i'll be getting insane RPM and a powerful motor, so this sounds like the best bet to me!

[suicideneil]

I would favour the 1900kv option as it will draw less current, and allow for more sensible gearing. Jzemaxx I believe tried the 1521 or 1527 and it ran the MMM very hot- pulls an aweful lot of amps.

oh right so do you think i should go for a 1515 then? would a 1515/1y be able to wheelie it? it seems extremely powerful in a revo and surely the muggy cant be that much more heavy

[suicideneil]

I dont think the Muggy is that much heavier either, but I think its worth having a bit of a dig to find the other conversion threads. I would either say the 1515 in 1700kv flavour to run on 5 or 6s lipo, or the same with the 1521. If there isnt that much difference in price between the two motors, then the choice is simple enough provided the batts are capable also. Mind you, the medusa 70 and 80mm motors are coming soon, worth thinking about as it will take you time to get the muggy and strip it/ convert it, ready for the motor and electronics...

if you insist on a 1521 go with the 1.5d on 5s and a 1y on 6s...remember with the extra torque that the 1521 produces you can gear up to get the extra speed you want, IMO stay away from the 1d it will pull too many amps

[bdebde]

I run a 1515 2.5D on 6s in my Muggy (check my sig for build thread). I would have got the 1521 1Y had it been in stock, but I am very happy with the motor I have (plenty of power). I think Satttheman has a 1521 1Y in his Muggy. I have a couple vids in my build thread and so does he (search "Muggy" or by username).

Pick the 1521 1Y, you can gear up for plenty of speed. The 1521 1D and 1.5D would just be some serious amp hogs IMO.

You won't need serious rpm unless you only do speed runs and only for short periods. I have a Plett Big Maxx that I have run in the Muggy a few times, it is 2300kv and rated 1800 watts (same as the 1521). It will really heat up my MGM 16024 esc and battery if I run for too long, and the power just flips the truck over with ease (not my favorite way to drive). With my 1515 2.5D, I can run pack after pack all day without overheating things.

the 1521/1.5D is only about 350kv more than the 1521/1y. everyone i've spoken to says you should aim to get the RPM around 40,000 on the Neu motors. if i get the 1y it will only be around 35,000. but with the 1.5D it will be about 40,000. will it really draw that much more amps? its not that much different. i mainly do speed runs because i am limited as to where i can drive and i have a very long street. I used to use a brushelss HPI Pro 4 for this but it was too sensitive and kept breaking parts so i want something that can be equally as fast but a lot more durable

[bdebde]

The 1.5D may not be too bad, just be sure to get good batts.

argh this is so confusing. i wanted to get a thunder power lipo but then i would have to buy their charger and balancer and it would all work out too expensive. i just want to buy the hypereion Net charger cos it seems like the best one.
