    Mmmkay..actual honest-to-goodness update time.

    After putting all the parts together (after dragging them out of my closet) I tried to figure out where I had left off last time I gave up on this thing.


    'lectronics.

    Repositioned the steering servo mount for better angles and more solid mount. Of course this meant re-doing the entire front of the truck, but whadda heck...

    Then installed mounts inside the "spine" for RX battery and RX. Throttle servo is already tucked away in there.



    Fuel

    Since I'm using aircraft tanks I installed a pair of filler-caps on top of the "spine". This allows me to run the lines inside the spine. Also made a combined tank support / fuel filter holder bulkhead thingy.



    Body work

    Since I moved the steering servo a bit downwards I re-made the hood mounts and made new dust shields from ultra thin stainless steel. Installed CF crud-catchers up front and on the side of the cage.

    Covered the top & bottom of the spine with thin 2024 aluminum.



    Suspension

    Made a new rear suspension arm mount; replaced the old 2-part mount with a more solid one piece mount which I also notched to hold a sway bar.

    Made a simple wire sway bar that I mounted to the lower arms. Seems to work well, time will tell if it needs beefing up.

    Finally installed long 1/8 buggy shocks with uber-stiff springs in the rear. After tweaking the angles a bit they work great.



    To Do

    Brakes:
    Still got the discs & "plunger" deal inside the engine mount, problem is just finding a good clean actuating system for it. Must ponder more.

    Throttle:
    Links & servo work great, just wanna improve the home-made bellcrank a bit.

    Odds & ends:
    Install tons of missing e-clips and such.

    I replaced the wheels. Didn't really like those Ofna ST wheels at all, so I decided to say the hell with scale, and installed the SinTec wheels that go with the tires. Much more off-set makes for a nice wide stance as well. I did dye em black to make em a bit more discrete though

    I gotta admit I really like the stance of the truck now; with the sloped nose and wider stance it sorta flows better imo.

    Anyways..



    A few more snaps..(shameless posing alert)























    Look OK?

    Thanks again guys for all this outstanding feedback!! I have finally gotten the to point where I am tuning & tweaking the engines in order to get them sorta harmonized. These babies do get hot though - first thing I did was melt a pullstart handle over one of the exhaust pipes

    Gotta luv the sound though; while I was running them on a stand today my neighbour was wondering if I was running a pack of dirtbikes in my backyard..

    I have a short video of the truck running on a stand as I was tuning the engines, you can see it HERE (2MB, right-click, save as)

    I have also finally updated the build-up description of the truck on my website; www.thorbob.com

    That is amazing! Much respect. I was thinking about building a smaller electric truck like this with independent front suspension and a TLT-1 rear axle.
