    New to Trucks and building something totally custom... NEED A LOT OF HELP

    Here's the short story. I'm part of cal poly state university's Baja team (if youd like to see what we and our car look like google cal poly slo baja and then click the first link) which is a team that makes basically a go kart sized version of a baja buggy and we run it for hours and hours in an endurance race. The main reason I'm here is because someone a few years back decided to build i miniature frame of our car at about a 1:5 scale. So i decided that since it was just sitting around I would try and make it into an awesome rc off road well... thing. The problem is i have limited experience in this field and i dont really know where to start. I have a competition ready rc Crawler, so i know a few basics, but I dont really know much in the way of speed demon rc trucks which is somewhat what i am trying to make. To start off, the frame i have looks a little bit like this (at bottom) or.. <a href="http://imgur.com/zYKT2"><img src="http://i.imgur.com/zYKT2.jpg?1" alt="" title="Hosted by imgur.com" /></a> I threw in one standard issue pencil just to give it some depth as to what size it really is. So basically I need pretty much everything necessary to make an RC truck go. The frame probably weighs around 5 or 6 lbs (yes i know its a lot). I'm not trying to spend a glorious amount of cash and the thing doesn't need to go all that fast (although the faster the cooler as long as its at a reasonable price). I need an idea for a motor (electric or nitro) a servo and well pretty much everything else. This thing is going to be totally custom but im trying to just get some components that will work well together. total im trying to spend is around a few hundred dollars(not including a remote i know those things can be pricy) but that can probably be changed somewhat because i dont know prices on a lot of things. So if you have any questions about anything that Im trying to do please let me know. To sum everything up... ummm.... HELP?

    The 1:1 version looks cool.

    That frame you have... not so much.


    That's just a mockup chassis and needs waaay more than just some RC parts to make it work, first off you need upper and lower A-arms, and cotter pins aren't going to work for hinge pins lol.
    Just find a used Baja 5B on ebay and drive it.

    RE: New to Trucks and building something totally custom... NEED A LOT OF HELP

    I know it's a bit of a daunting task.  I know it's going to need a completely redesigned suspension which I am actually looking forward to (new A-arms and new springs and shocks with new mounts not the cotter pins haha).  The thing I really need help on is choosing the right motor as well as the right servo and other important components that will be able to power and handle the weight of the frame (abt 5-6 lbs.). I know it would be a lot easier to just go out and buy an awesome one, but I'm really using this as a learning experience on how to design everything (being a mechanical engineer in school and all).  I just need some help with component choices such as the big one nitro vs. electric and which motor out of each that i would use.  Sorry I should've put that in there to begin with haha.  Thanks for the help!

    I would suggest looking at a Mamba Monster XL ESC and Brushless motor from the Traxxas XO-1.  Or from the Losi 5ive T or Baja 5b.

    You can probably "borrow" a lot of your driveline components from the Losi 1/5 stuff, too.

    Won't be cheap, though.  Hopefully you have some budget.
    Like the Thunder Tiger MT4 G3? Check it out on wondertiger.com

    The reason I suggested to just get an arealdy made vehicle is your budget of "a few hundred dollars" will likely turn into ALOT more than that.
    A good servo is going to be half of that, tires will be almost if not $100, so wheels and a way to turn them will probably get to your $300 real quick.

    1/5 scale wheels - $57 for 2.

    Even Redcat wheels on ebay are that much.
