Ok I just got the axial artr as most of you know. For the radio gear I'm going to run the AE xp3d 27mhz FM. Being that you don't need very long range with crawlers do I even need to run the antenna through a tube out the body? I haven't seen many crawlers do it...
 
some people use a peice of lexan and poke holes through it then run the antenna through the holes then mount it under the body, i just have mine wrapped from one side to the other of the rear shock tower bar thingy.
 
I just got mine in a tube, but put the body over it it goes just to the end of the back of the body.
 
your never more than 10-20 feet away from it, so you dont need it way the hell up there. But then again, you dont want it wrapped around the metal links, where it can possibly cause glitching.
 
Thanks guys! Another question where to mount the RX? I was thinking under the stock battery plate? Am I going to want it lower? I dont want to put it to low where it could get damaged though.
 
I have seen them between the front links, like on a piece of lexan, but i have mine, along with the ESC mounted on the underside of the top battery mounting plate.
 
You're gonna want it as low as you can get it. Once we get you all set up, you wont even be using that stock battery plate anymore. When you figure out where you're going to mount the battery, then we can decide where to put your other electronics. You will be able to mount it on the upper links, or on the rear servo plate, although I always try to get as much as I can over the front end and as little as possible in the rear for weight distribution.
 
My AM set used to glitch like hell unless I had the aerial vertically upwards. I've gone over to 2.4GHz now though so it's not much of an issue any more. I've seen lexan cards with the aerial 'laced' through them before like someone else mentioned, but I couldn't see anywhere to put one on the Axial that wouldn't be too close to the motor and/or ESC.

My RX is on the rear top links. It sits nicely in their and the shock-absorber cross bar and chassis plates protect it from getting crushed in a roll-over.

Weighting the rear of a crawler is a fine balancing act actually. What you don't want is it so light that it has no grip, but not so heavy that it pulls the truck either back on up slopes, or over itself on down slopes. Then again on down slopes if it's too light it won't sit down, and goes over the top.

Anywhere you want will work good. Wheel weights are a must and a battery on the front axel is what you need the most. I have mine under the top plate and it works just fine.

One day you will wind up with a custom chassis probably and be moving it. You can put the rx on the the Y links with a plate. There are a few versions of them out there.
 
You can make a plate for the upper links really easy. Most of the plates on the market are aluminum and kinda heavy, but you can use lexan to make a featherweight plate, like the porn star plate thats in one of the recent threads. I used clear lexan from a "pupcorn" dog treat container, because my dog goes through a lot of pupcorn so I have a lot of the containers saved just for the lexan. Also, get some heavy suty velcro to mount your electronics. It will hold just as strong as anything you'll need, and that way you can move your stuff around without having to peel the tape up, try to get the residue off, use more tape, and all that mess. With velcro, you can just switch the components around, or if you do like me and end up with 5 or 6 crawlers, you can swap components from one to the other easily. Just make sure that you always use the same side on the chassis and electronics, so they'll always match up, male and female.

If you mount everything down low, you don't have to use the battery plate, and it lowers the COG signifigantly. You might as well set it up right the first time.

If you run a battery that doesn't fit on the axle mount (which you'll most likely need to do to run a battery big enough for that puller motor), you can mount the battery on the upper link tray in the front, and the receiver and ESC on the low COG servo/battery mount on the front axle. Or you can just run the ESC up there and put the receiver on the rear servo plate.

I run my antenna in a tube against the the chassis long ways, but you might want to mount it vertically. If you mount the receiver on the rear servo plate, you can attach the antenna mount from the top battery plate onto the rear servo plate, and mount your antenna there. It will clear the body, and wont stick up quite so far.

I've seen a lot of people make a scale CB antenna holder, and make a "whip" style antenna, which looked rather scale, but I like everything tucked away under the body.

Just go to a spektrum radio and reciever, and you wont have enough antena to be able to see it. lol
 
Velcro is for rich folk, plus I have problems getting the tapes to stick down and stay stuck. Sometimes the velcro bind is so strong it rips the adhesive off!

I just use cable ties and buy them in bags of 1000 at a time. I know I'm killing the planet because I have to chop them off every time I move something but really, is it that bad. I think I've used about 150-odd over 2 trucks on 4 months so far.
