Looking for something to go into a slash 4x4.

This would be a good replacement for the novak 4.5 550 motor no?

Would the first one be good enough on 2s with a MM pro?

No.. its designed for 2wd

+1- 1/10 scale 540 size

That second motor would most likely require more voltage and not work well on 2s.

What motor would work good on 2s in a slash 4x4 with a MMM or MM pro esc?

Neu 1409 1y
3600kv, tons of torque and very efficient

Dang thats pricey at $140...
I guess as long as its worth it?

Well before you say its price, know that neu motors are close to, or THE top of the scale when it comes to motors

Quality materieals, designs and manufacturing makes them tops. Their motors are some of the most efficient (less power to heat, more to wheels), and torqui-est (made a word?) you can buy. Castle creations based their 1/8th scale brushless motors off the original neu design..
THey are one of the best money can buy and you will not be dissapointed

I know that...
I might of found a novak hv 4.5 for 35 bux... Then I might trade off my MMM for a MM pro...

If that fails I guess im getting the neu.
Thanks for the help.

Turns out to be the novak velociti.... Not the hv...

doh!

Im just going to run a CC-neu 2650 motor... Found a new one for a good price.
Gear it higher and it is suppose to be fast enough for the track.

Might as well run 4s :)

I have a couple 4s that I use in my revo conversion... 2s are cheaper and charge faster on my little charger. Fast enough for the track.
Im going to be geared 18/54 or 20/54... Depends what I like.

Maybe try one of the new Ballistic 550 motors with an MMP.
