    Fun! I did the same thing with my old Tamyia Nissan KingCab, but they have a bad transmission/differential design and I blew it up very quickly.
    I remember two friends who had similar cars as yours and I remember it being super fun!
    Ditch the mechanical speed control and order a $25 ESC and a fresh battery. The mechanical one has so much corrosion on it it will either not work at all or surly catch on fire.

    I wasn't originally going to but they are cheap enough and I do remember it was either full forward or full reverse, it was hard to get just a nice roll to it.

    I finally found the batteries I had and yeah, I have one on order now lol

    This past week parts started to finally flood in.

    New Shock Towers
    New Tires
    New ESC

    Painted the wheels, not perfect but I have another set of wheels and tires on the way, at least I can get rolling.



    It runs! Last night I was trying to get it to work and couldn't for the life of me, the instructions are backwards, I finally figured out how to get the ESC programmed for a brushed motor, but it still would not run. Then this morning I took another crack at it and dumb me had plugged in the wire on the receiver backwards (do not wire after a trying day at work -_-)... So I got it to move but I had no reverse... I finally figured that out.

    I am still fine tuning the remote and I have to get the steering dialed in a but (pulls right) but it works!

    I have new batteries that I think I may need to get a new charger for since I am not sure my Piranha fast charger will do the trick, however amazingly the old batteries are working!

    Last thing, I need to figure out what I am going to do for a shell. The original that I thought I had was long gone, and I thought about a trophy truck body, but then I was searching around and I think I have a new idea, I have the SC400 sitting in the driveway, I was thinking of maybe getting a supra shell, and stickers for a Lexus shell and making myself a mini SC400.

    It's nice to finally get to use it, I am sure I will be putting more money into other upgrades, but for now I can tart around a bit.

    So my enjoyment of the car lasted all of a week...

    First causality was the front shock tower again...

    Just an overall bad design, I went ahead and ordered another one and got that in. Need to look and see if there is anything I could possibly do to keep from cracking the mount....

    Next was a little more catastrophic, I took a turn and it started to sound like the time I blew my front diff...

    The motor mount broke, and in the process

    Took out the drive gear....

    And idler gear...

    I've ordered a upgraded motor mount so that should fix that problem. I have also ordered another drive and idler gear. Still metal drive gear, but no option to upgrade the idler gear to metal, but from my research there was an option and surprisingly didn't work out to well...
    Looking through the rest of the drive line, everything is pretty kosher, and it looks like when I built it I go roller bearings for it and didn't use the Nylon bushing like supplied, so besides the shocks and ESC everything that could be upgraded has been...

    Finished painting the 45 body. It will make a great basher body. I have not made body mounts yet.

    I got my new steeming arm installed. It was slightly longer and flatter then stock. As a result I had to space the servo up. I used 4 5mm nuts for that. Then I had to grind some of the arm and frame.

    So far, I've reused the stock servos and just enlarged the hole. Did this on the Traxxas, and the Vaterra. No issues yet.
