I have built a home made crawler. It uses axial axles so I figured i'd put it here. Here is how it went together. The chassis will be made out of aluminum plates. Here are the axles I am going to use Going to use traxxas links for it Going to make the links out of some threaded rod I decided to use a traxxas tranny and lock the differential. after filling it with JB weld bond and letting it set, I have a locked diff. Now to mock up and cut the chassis And a quick mock up as it was at that point Then a little reinforcement Now to mount the tranny to the chassis |

Now for the links Made the steering rods Then the uppers Then did a little work with some tubing to make everything pretty I think it works pretty good Now I decided to give it a real low crawl ratio via this The reduction box itself Little trimming I did a test fit with an old motor I had and its tight but fits |

Now to cut the body up Needs to be comp cut in the rear and major fender trimming up front Still need more V V V Better Now onto the rear before V V V That's better Now I just need to go mount it up. Mounting the body It starts here: Then mounted these: like so: made holes in the body: and there you go. Need to do more trimming, probably going to comp cut the front too and need more cutting in the rear |

Did some work started by taking the tranny out Did some trimming But realized I trimmed the wrong area at first, so I trimmed the area I needed too. Then cut some aluminum Drilled some holes And here is how it looks now, just need the motor to fill it up. Here is a mock up with my "test motor" |

Got most of the stuff together. I needed a spacer to mount the motor against, so I made one out of wood Here is the motor with the pinion gear on The gear reduction box Then soldiered the motor to the ESC Then went to getting the steering all set up Then after doing some testing, I found the reduction box was way to much, the tires barley turned with the motor run at full blast. So I just used the tiny pinion gear and it moves at a walking pace. |

A while ago I had dropped it and broke the upper link connector. Well I finally fixed it. new 3 link connectors to fix it. yup And reinstalled I had at some point changed to a servo horn instead of a servo saver, I never was able to use it though when I broke the first 3 link connector. Then took a couple minutes and cut the ends of the shock screws and the sharp corners of the chassis down |

This is sweet. I love homebuilds and the drill idea for a reduction was a great idea.
