Default oldskoolmini's 1/18 dodge 3500 prerunner (pic heavy)

okay so i'm fairly new to r/c vehicles and fabricating. But it hasn't stopped me from diving head first into my first scale r/c truck. the plan is to take a 1/18th scale jada toys dodge ram 3500 quad cab and turn it into a prerunner/ score baja racer. its a diecast body that is currently under the knife to shed weight. I am building an aluminum frame with 1/4" square tube to make a c-channel frame, then i will build a rollcage/bedcage out of 1/8" and 1/16" aluminum tube. i dont know how to braze but i will so learn. i also have my eyes on the 1/18 axle from rc4wd and will build the front suspension out of 1/18 duratrax vendetta parts and maybe fab up my own control arms. the wheels and tires will be rc4wd micro tires and wheels. i will post up the mock up pics when they are loaded onto my pc.

here are some pics of the diecast metal body i'm using. its under the knife to lose weight. the pics suck cuz my good camera died so im using my video camera to take the pics.


area where im gonna cut out the metal and add styrene flared fenders

area below the door. looked goofy with a "body kit" so it getting chopped off.

it came with a full show truck interior that will be replaced with race seats, roll cage, accessories.




yup it's got a hemi.

mockup with hummer tires that are the exact same size as the rc4wd micro tires. 1.90" outer diameter, 1.00" wheel diameter.

small update. the aluminum tubing i oredered came in yesterday. 1/4" square tube for the frame rails, 1/8" rod for the rollcage and some 1/16" rod for support peices to hold the rear fenders on and some other random stuff. also got a new propane torch and tubing bender. just waiting on my alumiweld rods from harbor freight. then i can start on the frame. what is a good way to bend up the raim rails? the bender i bought only does the round tube. do i just heat and bend the square tube to the desired shape? photos of the bending process would be very helpful thanks.

Stick the frame rails in a vise, heat, and bend. I wouldn't bend the same spot too drastically since you're using alumi. Bend it some then move it and bend a little more to keep from fatiguing the same area. Also I hear people fill it with sand to eliminate kinking of the square stock.

Also if you haven't worked with alumi brazing I would practice on some scrap first. Alumi reacts differently than steel or other metals. I've also hared you should bake the item first to evenly heat the metal so it doesn't crack when it cools. Cool it slowly. Hope that helps

thanks MojaveMonster! i'll look into that. the square stock im using has a thin wall. i have also seen some people pie cut the frame where a bend needs to be then braze the bend.


No real updates to post other than i have drawn out what the frame will look like and how i want to build the cage. I am having trouble trying to a small enough tranny to fit. also how do I lengthen losi mrc drive shafts?

This looks like a great project, really out of the box. I am interested to see the chassis come together.

Wow, thats a nice rollcage and chassis man! Looking forward to seeing this, it should be really cool. i dont think you can lengthen the plastic mrc driveshafts, so i would buy so larger ones. if they are metal then there is a way to extend them. Im not sure what a mrc has though as ive never owned one.

mini as in an old 79 toyota hilux minitruck i had. next check im gonna order some brazing rods and start fabbing the frame and cage. fabbing up some control arms still has me stumped. and I will be building a 1/18 diecast 2003 f150 for a friend soon too. his will be a crawler. ive thought about doing a metal mulisha style paint job on it. gotta bust out the airbrush after the body mods. just wait and see what i do for the front fenders.
