    Default Brutus - a GCM Comp Jeep Build

    HeyHo, everyone!

    Some of you will remember WAY back in 2011 I built and beat on this JK Brute with a MIL theme. Well, I've always missed that thing since 2012 when it found a new home in the middle of Canada.

    So... It's time to build another unit. This one will replace my DSTP comp Jeep (the white one) that I recently sold, and I'll be running this as my Class 2 truck for the next season. It will be built tough.

    The build list looks something like this:

    Body: Ebay Jeep JK 2dr Hardbody from http://asiatees.com
    Frame setup from gcmracing.ca http://gcmracing.ca/viewitem.php?productid=149
    Front Axle http://gcmracing.ca/viewitem.php?productid=165
    Rear axle http://gcmracing.ca/viewitem.php?productid=165 http://www.axialracing.com/products/ax30488 http://www.axialracing.com/products/ax80020 http://www.axialracing.com/products/ax30421
    Front shocks: http://www.amain.com/Axial-61-90mm-A...k-Set-2/p34269
    Rear shocks: http://new.dinkyrc.com/index.php?pag...mart&Itemid=63
    Front Bumper, modified http://store.rc4wd.com/Tough-Armor-F...10_p_1360.html or maybe another creation I come up with..
    Rear Bumper, modified http://store.rc4wd.com/Tough-Armor-R...is_p_1079.html or maybe another creation I come up with..
    Motor 17.5t Brushless red can from China, sensored
    ESC Mamba Max Pro with sensor
    ...(I used this same setup in my Twin Hammer and it was super fun and very smooth, so I have high hopes for this setup)....
    Transmission http://www.axialracing.com/products/ax30487 http://www.amain.com/Robinson-Racing...r-AX10/p107774 http://www.amain.com/Robinson-Racing...r-Gear/p107806 maybe, or I may keep the stock lower gear setup
    Servo is a bluebird 630mg works great.
    Lighting controller http://www.rccrawler.com/forum/vendo...ontroller.html
    Winch controller http://www.freewebstore.org/HeyOK-Pe...2_8019514.aspx
    Center driveshafts J90025 http://gmade.net/dealer/index.php?ma...roducts_id=313

    Intermediate shaft from Trans to Tcase from GCM.
    Wheels are GCM something, not sure yet, but will be 1.9 and CI CWR-3005 foams with 1.7 Z-T0117 swampers wrapped over.

    But.... first on to the body work end of things...

    I first started off with the typical 'China 2 dr JK', as we seem to call them. This one had a Boom Racing tag on it.
    I started figuring out where to chop off the roof panel to make the 'Brute' end of the truck. Then chop it off, It seems to be a good place to start.

    Next was to mark out the basics of the front end of the roof line now, to match it up with the windscreen bodywork. I scribed it out after some noodle scratching, and used another roof to get the proper profile, then felt confident to 'score and break' it off the main roof. Thankfully it didn't need really any sanding to get the line to work well, so I temporarily hot-glued it together so I can do test fitment.

    Right behind the door jambs on this is a couple of holes ready to mount something... the original cage or roof. In the case of Brutus, it's going to house the rear roof screws, just in the front holes. Perfect! Nice and solid!







    This also called for a chopped door. Mmmm my favorite Jeep look! The initial chop was just to get the frame out of the way, and not much more. I will clean these up real nice!

    Time to get rid of the back seat to make this a true Brute build with a full box out back.





    I also trimmed off the rear of the center console to match the back of the front seats, and it left me a very handy hole in the floor through into the cargo area, which I expect I'll be using for wire passage! Cool!

    I made up a new back cab lower section to match the profile also.



    I finished off the floor and sides again with some styrene and some hot glue re-inforcements as well, really just to hold the styrene while the shoe-goo hardens up. Got it all matte black painted as well.

    Lets clean up the doors: I took the door off right flush with the top of the inside panel, it's clean and didn't require any new bodywork to match up. I also notched out the rear of the door for the cab section match.

    I was happy enough with this setup to make a final gluing on the roof-to-windscreen, so I took off the hot glue and replaced that with a solid bead of Shoe-Goo between the layers, and filleted around the profile as well. Then I hot-Glued the end holes where there was a gap and knifed that flat after it was hard, so it can take paint.



    I had a hunch that the new rear cab area would prove to be a perfect battery mount, and I was right. I first started with the 2200 3s variety, and even though it fit in there, it was a tiny bit of a pain, so... I went for this 1800mah 3s variety which will have tons of punch and fits in there like a treat! The full size spare also seems to be a perfect match, although I don't like that much weight hanging around out back for a lousy 3 scale points.









    Oh, and I also cut off the fenders down to about 1/3 their original size, and rounded them up a bit for a nice comp look.



    AAAnnnddd... all that gets us to about here:
