I don't have any lipo gear at all, so would this thing be worth the jumpstart into lipohood... Or should I just go pick up another rooster ?

I've run mine on 7.2v 1500 mah stick packs, it does good also. Has more punch with the 3s lipo. I can get about 20-30 minutes of crawling time (not wide open) out of the stick pack.

Ernie, your brake issue is in that stock motor. If they'd used a 540 size stator and coil pack, they would of been fine.

What motor would you suggest I use? I traded for this truck a couple months ago and its my first brushless system, as well as lipo battery so I don't know too much about them besides what I've read.

Something a little like this:

It's $8... Worth trying. But, spend $25 on a known brand at a hobby store is more worth trying, if you know what I mean.

This might be an option to consider - http://www.hobbypartz.com/96m205-3660-1025kv-23t.html - as it is a true 540 size motor. I hav ethought about it, but for now the motor that came with the HW system does what I need it to do.

Pick up a cheap lipo and charger for less than a new esc

Awesome info there Badmuthatrucker will definitely be very helpful and the pricing on those type are sweet.

The tacon motor won't start up in a bind. You have to have an outrunner to produce enough torque for sensorless startup.

Shameless plug: My Revolver motor was extremely popular as a sensorless outrunner for many years. It bolts up like a standard 540 and uses standard pinions http://holmeshobbies.com/product.php...7&cat=0&page=1

I don't mind shameless plugs always nice to know where to find the right stuff

[Badmuthatrucker]

Sorry John, didn't realise you still had outrunners. I'll get me one I think

***Edit***

I just bought two

Cool, might have to look into one.

[Jersdunz]

There are hobbywing motors made low kv specifically for crawlers I have never ran one but can definately vouch for alex at value hobby all my orders there have been fast and accurate..

Slow motor does not make it a crawler motor. Probably just as good as the Schumaker "crawler" motors that were just slow two pole sensorless inrunners.

so since there about the same price the revolver would be the better way to go then.. Sounds good to me.

[JohnRobHolmes]

Considering they list it as sensorless, I would say so.

I just wanted to say I pick up a Revolver from the classifieds and got in hooked up last night. Keep in mind I'm currently on a 1500mah 7.2V standard battery.... I can't believe the difference it made. I have great brake power now. Wheel speed is faster, I'm running 87T-14T trans gears. The stock EZRUN motor was slow then picked up ( is that cogging? ), the revolver just goes. I did get in a hard bind and popped a Traxxas stampede drive shaft. I believe once I do MAXX shafts I should be good to go.

The Revolver outrunner also has a sound of its own...... I like it myself.

I highly reccomend anyone running the EZRUN crawler brushless to pick up a Black Revolver outrunner from Holmes Hobbies.... they are the bomb.

[bugman72]

Hey, JRH...what size ESC would you recommend then with the Revolver? Would a 35A be sufficient on a lightweight 2.2 (my old BMVII) running 2S 1300Mah 40C Lipo? I wasn't sure what the load draw is on your motor.

[JohnRobHolmes]

yes indeed, a 35a ESC would work well. You could even get away with a 25a model with proper gearing and temp checks.

[bugman72]

I might have to go this route then. Once HobbyPartz gets the 35A back in stock (they say in less than 2 weeks), I can get it as well as your Revolver for around $65 as a package. Not a bad price for a capable brushless setup.

Now, when are you going to find a new supplier for the brushed motors for my Losi Mini? Or, do you know of a good outrunner that I could run in it?

[JohnRobHolmes]

A little 22mm diameter outrunner would do well, but it has to be fast to hit the speeds you need. I haven't really looked into them yet. Something around 4000kv.
