i was just wondering.
ive got a velineon system in my rustler VXL for now but i WILL be upgrading to a mamba as soon as i can afford it.

but do i stay with the velineon motor (rebuildable) or get a mamba 5700.

i do not want to run cooling fans for long runs etc.
i jsut want somthing that's gonna be fast enough to compete with a few LST's and trucks at the track and a good basher

or even a feigao motor in hte L size[&:]

5700 or velineon??

p.s the batt is gonna be a maxamps 2s 10,000mah lipo

The 3500 will make more power at the same voltage of 2S. It is a little bit bigger motor.

That's not exactly true. With the same gearing, the 57k will produce more power because of it's high Kv. The Velineon motor has better windings and overall is a better motor. It also runs very cool. Don't let the low Kv fool you. Just gear up a few teeth, and the Velineon will haul and still run very cool.

I would stick with the Velineon motor.

shaunmichaeljohnson

do you mean tourque?
a lower KV typicaly has more tourque right but less RPM.

the idea with hte feigao was to get a larger motor with a higher KV, that way you get higher RPM (speed) and keep the same tourque because it's a phisically larger motor[&:]

What speeds are you looking for? Yes, it will have more torque. Basically, the higher Kv will take more power at a time and produce more power. It's the same as gearing up, essentially.

Who is voting the 57k..... Seriously.....

Don't waste your money on a motor that isn't as good quality. Spend your cash on a couple different pinions..

Since gearing is nearly unlimited and your limited to 2S then the largest motor will be the fastest (vehicle speed)

For your poll , what is it that you're asking? OR what is the goal?

If I understand your application weight isn't real important becuase of the battery and so the largest motor would be in order. Pick a high kv because of low voltage.

Always Dreamin

The Velineon is very flexible in gearing, and on top of that the quality is very good. Unless your trying to set a speed record, the Velineon will have no problem pushing you past 60 mph, and have enough torque for the car. More torque in the Rustler is just stupidity. It already wheelies, there is nothing else you need more torque for. It's 2wd, and light. It can wheelie all day. All you should care about is temps and whatever else your shooting for. Just saying, if we're comparing the motor quality of the two, the Velineon wins. Feigao, don't know too much about, but I can tell you that you would be best with the Velineon over the CM36.

Just ask Takedown. [8D]

Like I said high Kv is the same as gearing up, from what I've seen.

Kv, and gearing aside, the Velineon is a better motor that uses better parts.

KV has little to nothing to do with torque once the motor is spinning.

This explains why in detail.

The differences in torque between those two motors have nothing to do with the KV numbers. It's the difference in construction. And both motors will do the job, there is no reason to change from one to the other. They're both solid motors. But if you were running the VXL motor, I'd use a 3s LiPo.

You get the award for electronics Guru on Rcu. That's amazing. Found it hard to keep up with.

Chris_RC

I dont get this whole the lower the kv or higher the turns, the more torque is has. Look at[link=http://youtube.com/watch?v=8a-bz8RJ4aA]THIS[/link] video of a xxx-cr with a Novak brushless 3.5R motor. I have no doubt that it has more torque than a 17.5 or 21.5 brushless Novak motor. So why is that?

Always Dreamin

That's what Access just linked to, read it.

shaunmichaeljohnson

ok then i'm getting the message to stick with the velineon motor with the 2s.


my goal as stated above was to compete with a few LST's at the local track.
that is a tall order i know with 2s

ok then i get it...just gear it up

same deal essentially, now i just need new tyres to get that damn power to the ground!![:@]

thanks for all the help

Always Dreamin

You could always get 3s? [8D]

Get some Pro-line tires, they have lots. Yes, if you don't get enough speed with the Velineon, you have a couple options. Gear up, more volts. Simple.

Chris_RC

Proline has some good tires but they have really bad foams and stink bad when you take them out of the box. Losi pretty much has the same wheel types but different names and they havee better foams IMO and they dont stink. Like Holeshots=King Pins

sloppyG

jconcepts makes some nice tires too, and the foams are really nice compared to proline ones

Always Dreamin

I can't believe how many people voted CM36... Don't pay attention to them shaun, they haven't even posted why.

Access

That's why you don't use polls for things like this, it just becomes a popularity contest.

This is a common sense question. The CC CM36s series motors are terible IMO. They heat up like no other motor out their and the windings in the can are not only less than other motors they are even poorer of quality. Do yourself a favor and Get a MM ESC and the velineon 3500 motor. One of the best cheap 1/10 combos around.

Access

If you talk to patrick he said they have made improvements to the CM36's in the last few months, so they run cooler and can safely hit 80,000rpm, 85,000rpm, etc. Talked to him at the AUVSI show a month or two ago. Hopefully this pans out in time.

And they were good when they first came out, but now that sintered rotors and all those other things have become standard, they're just average and yeah they tend to heat up like crazy.

Always Dreamin

Well, judging by the poll, it looks like you should get the CM36.. So you go spend your cash on one and then report back.
