Bondo's 6X6 Scale/Crawler recovery truck - 06.10.2012, 08:10 PM

Here's what I'm starting with, these are pictures the guy sent prior to making our deal. This thing had some serious issues when it finially showed up considering I was told other wise.

This is a RC4WD "Beast" 6x6
http://store.rc4wd.com/The-Beast-Bla...le_p_1175.html

During inspection I found;
5 broken off 2mm screws between 2 axle cases and over a dozen missing screws. The Mann body was broken in several places and all that was included was the floor pan and exterior shell, not sure if anything should have ben included such as door handles and hinges etc ? The servo mount was broken from crashing into something but it's reusable if I place a thin piece of alum over it and screw it into the Delrin. Also one of the front carriers is hogged out top and bottom from the missing kingpin bushings and someone just put a screw in and it worn the hole oval, real brainiac. And last but not least, the frame was bent in 4 places, no clue what they were doing with it ?







Once I received I was able to get a decent pic

I removed all the running gear and electronics and set them aside to get the new tires mounted up to make some room on the bench plus to see what needs to be done with the dual axles to make room for the taller tires.



Wow, what a PITA these rims are but they look super dope

Next I tore down the 2spd tranny and found the idler gear pretty worn but with plenty left on it to last a while yet. I checked all bearings and bushings, cleaned everything and reapplied Mobil-1 Red Synthetic grease.

I then moved onto the original steering axle and drilled and tapped the broken
2mm screws and did a thorough cleaning and again used the Syn grease.





I bought 2 more steering axles from Rock @ RC4WD and tore them down as well and applied Syn grease during re-assembly.

Heres a good pic of the body, for those whom aren't fimiliar with these kind of 1:1 truck I linked some You Tube videos of these beasts having fun. I'm going to cut this body up a little bit to make if a bit different than the norm.



This driver and truck has the main inspiration of my build.

Made a new rear plate, it's a bit bigger than the stock one which was steel and weighs about the same even tho theres a lot more material. I Incorporated a rear bumper and loops for the tow hooks.

Rear bumper braces and loops for the rear pull rings/shackles.























This is all what I'm using to do the brazing/soldering





Here is is painted with "Hammer Paint" spray bomb

Looking good Jeff.

I had one of those chassis, a while back. Mine had lowly tlt axles and ran a cut down pede tranny with an axi 2217 (1100kv, and about 1" across, tiny motor) on 3s with a mm.

It would almost crawl vertical. Incredible. And I only ran 1.9s. I cannot imagine how your will run with all that power...

Thanks James, I tested several motors on 2s the results were lack luster at best due to the weight of this pig. At the time of tests there was no body or bed was basically a roller with all electronics and it plumped out at 10.7lbs !
I tried a 55T brushed, 1400kv Outrunner, 1900kv sensored 540 and the power was inadequate. Tho it moved nicely climbing was under powered badly, I also tried a Tekin 550 SC4X 3300kv but it was waaaay to fast. The 1400kv T8 on 3s should prove to be very ballsy and run efficiently.

These trucks have fascinated me since I seen the first video last year, I searched for months befor I found a decent priced used one to start this build. I would love to see them in person myself, I like they way they set up the courses as well. It seems like they purposely try to get them stuck and the crowd cheers all the harder when they can get out.

Please bare in mind most of what I'll be posting is weeks old that I'm copy/pasting from my Losi Forum I mod at. When I get around to getting to the more recent stuff I'll be sure to let you know when I post it.



I tried the new sheet metal break from Habor Freight and Tool and the thing works excellent, several vise grips are needed to hold the material steady in the tool but other than that well worth the price paid !

I made 2 electronics trays today and once the lenth is determined I will cut off the excess. Some make think I'm crazy but I decided to use Brass rather than aluminum and I'll explain why. Once the aluminum is bent 90* it cantr be bent back with breaking at the bend. Also I can solder braces, brackets, cab mounts etc etc right to these plates. The brass is a tick heavier than the aluminum but way lighter than the factory steel plates.















This entire sheet of brass is several grams lighter than this steel plate at 1/3 it's size.

I had to extend the drive shaft between the #1-#2 axle, I used a 1-1/4" piece of solid Stainless Steel rod.









The springs on these shocks are really feking stiff, In this flex shot the spring will not fully compress. Maybe once the installed body, bed, battery and the rest of the electronics they'll be fine ?

The scale winch I bought is really cool but under powered for such a huge machine so I got brave with a brand new Hitec HS7950TH servo and used the scale winch controller to make a bad assed winch with. The servo has 402oz @ 6v so I'm confident it can hack the pig I'm building ?



Now to hit the craft store and score a "bobbin" for a winch reel.
