Default 1/8 buggies and 540 size motors

I have been looking at the Hotbodies Ve8 and the RC8e and noticed that they accept 540 size motors.

I know that this will probably be an underpowered setup for now, but can I run a 540 sized brushed motor? I have a Traxxas XL-5 speed control and 540 Titan motor that I would use to get it started. In the future when more funds are available, I would go with the Mamba Monster.

I also know that I would have to pick up a servo. What are decent/cheap servos to start with?

Also, could I use 2s lipos in parallel? I have those for my Slash 4x4..

I know that most of you guys are racers, but I would use it for bashing mainly now.. I want to get into the 1/8 scene and want to see if this will work for now.

not a good idea using that motor and speed control, i doubt it would move a 1\8 buggy very well, and i can gaurantee it will get smoked

I ran a 540 sized motor for a while, but it was a 4 pole brushless Medusa.

I tried some testing on brushed motors before spending the money, and I melted the end bells on 2 of them in no time at all. Even geared for silly slow speeds, the currents were just too high. A Traxxas VXL system geared for 25-30 mph on 3S would live for a while and be fairly fun. Anything less will not live. I currently use a 1/10 Mamba Max ESC, but it is connected to a Neu 1512 2.5D motor which is a 1200 watt 2050KV beast. And I actually do get it pretty warm with it geared to go 33 mph on 4S. You can build a fair budget setup, but choose the parts wisely or you will just burn things up and end up spending a lot more in the long run.

You shouldn't run a brushed motor. The 540-size ones aren't powerful enough and the 550-size ones, which will move a buggy, albeit not that fast, require higher voltage (at least 14V...12x NiMH or 4s LiPo).
The smallest motor I'd recommend is a brushless 2-pole 36x60mm motor or a Neu 1509-size (39x50mm) motor.
If you're looking for a very low-cost setup that will run a buggy just fine (it may not be competitive with the very large systems most people run at the track, but will be plenty fast and stay reliable), shoot me a PM for some recommendations.

Wow is all I can say. One the car won't even move with that motor in there, two you need at least a 3s battery. And xls won't take that much power. Not trying to be mean but it's kinda a stupid question.

well with the 540's?? wont move it real good?
best bet, i know it's tough but go with a better system....
you can get the XeRun 150-A for $129.00 there just like the Mamba's but they can also use Sensored motors too, can program them as well....
i know a few guys using these at a couple of tracks i go to,there really good! getting one myself for "Back-Up" i have Mamba's but never hurts 129.00 it's a good deal!

servos, hit up Sammymoto at: [email protected]
has 200oz. at .09 speed, servos for 64.00!! been using these in my 1/8 scales for a couple years(truggy and Buggy) and just got 3 more for my other cars.
