neu 1512in an e-maxx ?
 

Hi !

Would an neu 1512 2050kv motor be enough to power an e-maxx ? on 4-6s lipo ?

Yup. But I wouldn't use 6s on it. 5s max.

I put a CC2650 in my Revo on 4S and it booked along nicely. Not quite a wheelie prone as a 1515, but temps stayed good.

I would say yes assuming you don't have a heavy all alloy maxx. 9lbs max or so and you should be ok. 1515 is a safer bet tho.

Agreed. Seen plenty of maxxes running L can sized motors, stick with 4 or 5s and you cant go wrong- just gear accordingly (30-40mph region with a stock-ish weight truck).

would an e-maxx 3905 handle an neu 1521 or 1527 motor ?

I doubt the diffs would last. A 1515 size motor can handle just about any emaxx combo, save for some giant tires or ultra speed setup. If you are just bashing a 1515 will be plenty.

A 1527 is a big fraking motor. You might be able to make it work, but it will need a lot of work/mods to be anywhere near somewhat reliable. I imagine you may spend more time repairing the driveline than drving it. Forget about ever having the F wheels on the ground.

A 1521 would probably work, but again would need some work to be reliable, esp if you want to go big power. I can't imagine the little TRX diffs and plastic driveshafts living very long under that much power. I don't know how well the tranny or slipper will fair. The tranny and slipper on my Revo blows up enough w/ the 1515s and 1512s I've had in it.

Really comes down to how much cash you want to spend and how insane you want it to be. Bigger than a 1515 is OTT.

are savage's more durable than e-maxx?

What is it you are trying to do exactly?

Hehe !

I'd like to have an crasy monstertruck for hard bashing with stupid amounts of power :O)

I have been using a 1512/3D 6s lipo combo (1700kv) for over two years now with great success, excellent temps, and perfect power for bashing and racing. Max temps I see in 85F weather is around 125F when racing, and 145F when hard bashing. Although a 1512 motor DOES work for a 1/8 (revo, maxx, maybe truggy), I would recommend a 1515 just for the sake of lower temps (even the temps I get are well within safe limit).

Power levels on my setup have hit 2400watts spikes running 6s G3 lipo and geared for 45mph.

If you are wanting to have a truggy in the future, I would definately get the 1515 motor, just because a truggy does not have the air flow that a monter truck like a maxx or Revo has, so they would run hotter in a truggy, or buggy.

IMO, I would get a 1515 motor, just an overall better bet, you are not getting much of a benefit with 1512, besides lower rotor enertia, a more snappy feel, and a lower motor weight as well, which might be nice in a "light weight" setup.
