The sound of brushless

Recorded this on a near-discharged 8-cell pack. MM5700

*EDIT* Jesus. Stop commenting about how "bad" this is for the motor, especially if you don't actually know what's going on. Yes, I know that over-revving a brushless motor will damage the rotor. Yes, I know that this happens when you rev it with no load.

I also know that this truck wouldn't move under its own power because the pack was nearly completely discharged. There's no way in hell that the motor would over-rev. In fact, I doubt it would have revved any faster than if I had been holding the truck in the air on a full charge. I see that all the time, and no one says anything about it.

There's a reason that the motor doesn't sound like a "screaming girl".

So stop it with the "bad for motor" comments, and learn something about brushless. The motor is still running nearly two years later on 8-cell and 9-cell packs.

If you're wondering why I did this in the first place, I was responding to a question on a forum regarding another poster's motor issues.

bored??

@Lekkereddy Someone wanted to know what a healthy brushless motor sounds like since they thought theirs had problems.

[EMAXXMASTER]

thats fantastic that u have a rustler and i have a emaxx with Mamba monster and a slash 4x4 with mamba max 6900kv running on 6s lipos and my computer is also liquid cooled is ur comp liquid cooled? i dont think so.

[cryptology]

That's nice and all, but I didn't need or care to know all of that. If you just want to grow your e-peen, then you can go somewhere else and do it. The fact that you spend money on things that won't help you advance in life, and then brag about them on YouTube doesn't impress me. Thanks.

yo bad for the motor i got a nwe 4x4 slash beast

[cryptology]

How do you like the 4x4 slash? I've been considering converting my brushless Revo to a Slayer, but I'm not sure about the shorter A-arms and stuff.

this vid is pointless

[keyhanoboy]

they don't sound like brushed at all.... if he actually punched the throttle it would sound like a little girl screaming.

[BexonBoy123]

@arcadeidiot3 FAIL you'll just blow your esc in your revo ( un less if u have a different brushless in it) the vxl 3m esc can only go up to a 4s!

[arcadeidiot3]

@EMAXXMASTER think your emaxxx is fast on a 6s huh ill run you against my mini erevo on 6s k? o and liquid cooling a comp is a waste of money.....

[EMAXXMASTER]

@elitecamaroz28 my emaxx is beast. blew the drive shafts lol so igot them in steel as well as axles. and the slash is light so 6900kv push at like 55 mph

[elitecamaroz28]

@EMAXXMASTER liquid cooling is a waste of money! How do you like your Emaxx with the MMM? What kv motor did you get? Isn't the Slash to heavy for 6900kv?

[triplehhh478019]

okay he just dicovered a motor

wtf

[MrAzzatron]

i'm very new at this rc game, so i quess what you are trying to say is the brushless is rather quiet? Although, what i have picked up so far, the brushless is a lot better over the brushed, right?

[Staudte2008]

Sounds Boring...

[MrSpankeyhankey]

Sound? LOL!
