brushless opinions for a slash

[discgolferlee]

so I want to go brushless with my slash and I need some feedback on a couple different setups.I currently run a venom 4200 7 cell pack but am thinking of picking up either a 2s or 3s lipo. Still running stock gearing and wondering what gearing changes are reccomended for keeping temps safe. I don't race it just more of a basher round the track and yard. any input appreciated. thanks in advance.

thinking of going with
cc sidewinder 5700kv combo
or 4600kv combo

also considering the novak havk 8.5t sensored combo.

all 3 around same price or maybe even with this combo

I have a 4600 with a 3 cell geared to the moon and its useless over half throttle, a 4600 on 2 cells would be more than plenty.

I've been running a Castle 4600 combo with a big 2s lipo for a while now and I woudn't want any more.

I haven't changed gearing since I got it. I know it come swith the high speed pinion. I think stock is 18/86 and the extra pinion included is hmmmm no idea. never even took it out of package yet. any gearing reccomendations for the 4600 or the 5700. I think my LHS only has the 5700 in stock right now.

I've got a Novak GTB with Velociti 5.5 (7400KV according to Novak's charts) in mine. I'm running some cheap Epic 3000 NiHms. I've got it geared way low at 13/86. It's top speed calculates out to about 36 mph with a run time in the range of ten + minutes. I don't know what my actual temps are but the motor and ESC barely get warm. The battery on the other hand has gotten pretty hot.

I keep it geared down because of battery quality but the speed is still respectable. If I throw any more volts or taller gears at it will start getting into the crazy range. I already want to do some work to the diff to keep it from unloading in the corners. I roll it all the time on the street if I'm not careful about the whole throttle control and corner thing. 7 cells with the current gearing is about all want to go and still keep it what I consider controllable.

I put a vxl system in my Slash. 7 cell 5000 nimh packs. Stock gearing. Pretty incredible power and great run times for me. Not too short nor too long. I have since gone back to the stock set up xl-5/titan for snow bashin. You get a ton better handling if you add some 50k (or your choice)diff fluid.

Go with the 4600. plenty fast on 7-8 volts, silly fast on 3S.

The 5700's get a bit warm in a Slash.

im also in the market for a new motor for my slash
ive tried the 9,000kv and it was just way too fast. id get cogging at even the slightest hint of throttle (*mainly because i refuse to convert to lipo)
when i finally get to speed the flightest bump in the road would get the thing airborn.
and when i do use a borrowed lipo, a quick squeeze of throttle and the thing wheelies and flips over, even at speed

i was thinking about going w/ the 5700kv, but like many have said the motor tends to get hot. would installing a heatsink onto the motor remedy the problem? if not a regular heat sink, how about one w/ a fan on it? since im using it mainly for bashing is the fan breaking off on a hard fall going to be a concern ?


*btw should this be in the non crawler rc section?

Brushless, or brushed?

Great brushed:

As far as brushless, I like the Velineon.

4600kv with Sidewinder on 7cell 4500mah is damn fast thats all you need
