  • 1/5 scale Traxxas Yeti

    I'm just getting to the end of this build.
    So I like doing things a little different. I also like to build large scale lately. This build is no different. I using Traxxas 3.3 Revo parts, Summit parts, HPI Baja parts, Hitec 1/5 servo and a custom frame of my own design. Money is tight at the moment so this build will be a little slow. I do have a lot of the parts already so it shouldn't be to bad. The Axial Yeti cage will be about the only thing that has anything to do with the Yeti XL but it will look like one when it's done, sort of.
    Here are some of the parts being used
    Hitec HS-5755MG steering servo
    Summit 2 speed transmission
    Summit front locking diff. with LEM 7075 cnc diff cup
    Slayer Pro front bumper
    2 Traxxas 2065 micro servos
    RPM revo arms
    Traxxas aluminum hop up parts
    1/5 Proline trenchers/RC4WD Dune Reapers
    Traxxas Rear diff spool
    Custom aluminum stretched chassis 17.75'' (45.09 centimeters) wheel base
    HPI Vorza Motor mount
    Leopard 4075 brushless motor
    Axial Yeti XL roll cage
    Traxxas Slayer front bumper
    Summit shifting links and mounts
    HPI style 1/5 bead lock rims
    150 amp 6s speed control
    And a hole bunch of custom parts. Including a scale fuel injected blown motor and interior!

    The wheel base is 17 3/4'' long and 17 1/4'' wide out side of tire. That makes my build a inch wider than the Axial Yeti XL and 3/4'' shorter. I hope to try this build out against a built Axial Yeti XL.

    This is the roller that I picked up off of ebay years ago to do a build like this. The funny thing is that I did't really know what I was going to do with it untill the Yeti XL came out a few months back.
    I think I won the bid around $100.00 just as you see it here.

      I just ordered the micro servos as well as the Roll cage today. The Revo rear wing mount, I ordered 2 days ago. so I do have some parts on the way. The custom frame is cut already and I made the custom drive shafts also. I have the chassis as a roller and when the Roll cage gets mounted I will build the Custom lipo trays so that they fit as they should. I will mount them with the weight forward so that it is a great climber.



      The picture above shows the HPI Savage 24mm wheel hex adapters that are needed to use the 1/5 scale rims. They work slick. I have tall narrow tires that will set this build apart!

      This is the bomb proof motor mount that will be in this build. it lays the motor on the chassis, so the weight is as low as possible.

        This picture shows a frame that I used to mach up the wheel base and lay-out.


        Here are some drive lines I'm playing with. because of the custom length I needed to make some.

          I tried this chassis out and it worked fine, but I wasn't happy with the twist flex that it had. So I went to the scrap yard and bought some RV awening legs to build the frame from. It is important that I have on flex between the motor and the transmission.

                Here is the mount that I will use to shift the front diff and the trans.


                The micro servo came in today. That is fast! I live in wasinton state and thes came in from JK Hobby in N. Chelmford MA.

                  I'll be using the RC4WD Rod ends both long and short on this build and also in other up comming Builds. I like them. they seem to be well built. I will givee a full review as soom as this build is done.

                    You can see the difference in the size of a normal servo to the larger 1/5 scale servo in this picture.

                          I picked up the interior for this buggy also. It comes with 3 sets of helmets.

                              It took me 1/2 hour to figure out how to mount the back of the cage to the body post of the revo mounts on the chassis. I'm using a broken drill bit as the hing pin for now. So it works and it doesn't stand out. All good things in my book. The front was easy. I moved the hood pins to the back of the mounting post bracket and drilled holes and bolted into place. I drilled the holes in the hood that is 1/2 wider that the Yeti XL mount but in the same location so it is strong.
