With lipo 2s 3s etc stand for the number of cells within the pack. Each lipo cell is 3.7v, so a 2s pack would be 7.4v, 3s would be 11.1v.

As for steering servo you want to shoot for the most torque you can afford. I prefer Hitec branded servos, but Savox seem to be pretty damn good, and i've been running bluebird brand servos lately with a fair bit of success.

As for a BEC is stands for Battery Elimination Circuit. It is a bit of gear that eliminates the need for a separate battery to run your servos. Most ESCs these days have them built in, but they are not up to the task of running the high torque, high amp draw servo's needed for a crawler/scaler. So you run an external one that is capable of handling the amp draw. Personal favorite is the Castle Creations 10amp one, but a cheaper option is a 5amp cheapy off ebay or hobbyking.

What ESC are you intending on running?

What ever you tell me mate . Azwa and lunatic said you were good at dumbing it Down so I'm in your hands .im not even sure on the motor brushed or brushless I would like to just do it right and stop wasting money on wrong stuff (getting bored hanging out at the letterbox). I would also like to be able to run my fancy new 2.2s with no probs . If you could give me some ideas on complete set ups that would be great .i will drop the carton round later .

If you want to buy some decent gear once and for all go for a Holmes Hobbies BRXL esc paired up with any decent brushed motor in the 35t range and you're golden.

If you're a bit lazy and don't want to worry about the maintenance that a brushed motor needs. You'll want to go brushless. For the esc i would go Castle Mamaba Max Pro or a Tekin RS and for motor any sensored motor from 21.5t-17.5t.

Servo is the same as what i said, go for the most torque that you can afford. Something like the Savox 1256tg would be perfect. Make sure you get yourself at least a cheap 6v/5a BEC to run the servo.

load all that up on 3s lipo and you have a nice crawl with some wicked snap for when you need a bit of speed.

Yup.... It aint cheap. But it's a buy it right, buy it once kind of deal.

As for RTR vs. Kit, that comes down to personal preference. Kits work out cheaper in the long run, but RTR will get your running sooner.


Check out hobbyking.com for cheap lipos & chargers. Go straight to holmes Hobbies for the motor & esc (if you're going the BRXL & one of his motors) and don't forget evilbay can be a source of some gear at very cheap prices.

Ok this is the plan get a castle creations 10amp bec , about a 5000 mah 3s lipo and the b6 charger . Will try and run that with the ae2 esc and standard servo then update esc/motor to hh 35t then do servo . But I'm pretty sure something else will break/meltdown between then maybe I give racq a call and se if they will do fire and theft cover on it lol. Do you think this will work or am I just starting a fire without matches using the ae2. Thanks mate for all the help I know you've probly got better things to do .

You're dicing with death on the AE2, but a heap of blokes in the states are running them on 3s using an external BEC without a problem. The servo might last a while until it flogs out the bushing that supports the main gear (which the stock axial servos are notorious for)

Just make sure you pick up a castle link usb adapater so you can program the BEC and AE2 using your computer.

i don't know if it helps or not but i was looking at getting a tekin esc / motor combo from tower hobbies at it is the cheapest place i can find them and only about 20 dollars more then i can find the holmes hobbies for. I don't know if they are any better or not others will have to tell you this have never used either, but thought i would let you know.

by the way i am new to the forum and crawling so hello everyone.

I would also like to know what would be better for the money the tekin or the holmes hobbies myself.
