Hey everyone!

When the TRX4M Bronco came out I really liked the looks of it. I suppose its because I like the new Broncos but would never personally own one (No offense to anyone who does, if my wife wanted it I would back it in a heartbeat). I also wanted something I could fit in a small hardcase, kinda like the size of a lunch kit.

I started out initially happy with my purchase. Yes, it seemed underpowered but I liked the foundation. I set out to replacement basically everything on it with TRX accessories, eventually swapping some out for other brands (aluminum for brass, wheels + tires, etc.). I tried the TRX method wheels with their tires and weight sets.

I also picked up some RC4WD Black Rhino Armory wheels and Goodyear Wrangler MT/R tires. I wasn't happy with the performance so I went away from scale and bolted up a set of Mud Slingers.


I had came across Furitek's Lizard line while scrolling and wanted to give it a shot. I also wanted to up the voltage to 3S. I removed everything, esc, servo, motor and began laying out new components. I built a shelf out of left over Lexan to place the RX on over the rear axle. I then stuck the Lizard ESC on top of that. I brought it to my LHS to show them this new Furitek stuff, at the time they had never seen it in person. They're now a dealer :cool:

I used the truck on and off but I wasn't happy with the electronics. I decided I wanted to stuff a larger can in there to help bring temperatures down.

I tried other motors by Furitek but I wasn't satisfied. After careful consideration I opted for a Hobbywing motor that would just fit in there. The turns are lower than what I would like, but on 2s it works great! Temps are low and there is plenty of wheel speed when needed. I had to completely redo the electronics layout, but it's worth it.

Another thing that I started to mess with was the lights. When I switched the body from black to white I left the pro scale (?) light kit in the black body. A Canadian company sells a light controller to be able to reuse that kit so I ordered it up and swapped those in. Some other updates and upgrades are some parts from LGRP.

I ordered up a set of wheel and tires to try. I threw them on a few weeks ago but they were definitely the wrong tire for the terrain. It was a place I hadn't crawled before, I usually go to a quarry. This was close to my new house which was better than a 45 minute drive. Unfortunately it was soft sand and the TRX4M wasn't much fun to try and drive with pin tires. :(
 
As I mentioned that in my op, I picked up a hard case for it. It's foamed lined and fits in there perfectly. My plan was to keep it in my service truck but it never made it in there. Plus, at the end of most working days I would rather be home with my family :)
