Default Buildin a Bronco

I picked up this TXT project back in '08 for something to do over the winter. Soon after that I bought a house an the truck never got touched! Finally sat down with it recently an started putting things together.

Here's the cut chassis with stock links and Integy MR11 shocks sitting on stock axles. Locked rear, LSD front and trimmed knuckles for a little better steering.



This shows the material I shaved off the transmission end of the Revo shafts (only really needed on the motor side; for the back end you can just trim the heatsink.)



Driveshafts installed on shaved transmission:



Transmission installed, with braces:

Apparently I'll be running two different types of Losi Claw MT's. Bought all four at the same time but one set is the original and the other is I guess the newer style (with voids in the larger lugs.)

700 with no RC4WD reduction.

Does that thing bolt up, or do you need to make some holes?

Oh man, how about that motor plate with only one motor? What was that? From a dump truck I think? Didn't that transmission have a different gear ratio, also?

With the 700 I'd need to enlarge the main hole and the adjustable screw hole on the motor plate.

You're thinking of the Tamiya Mammoth dump truck. Kona_Joe's page about the tranny is still up - LINK

Exactly! Ahhh, blast from the past. Thanks. I need those occasionally to remember where I am currently, and why, and how I got here.

I've got the tires mounted up on Maximizers with a 1/2" offset. Same part# for each tire set but you can see the difference:


The foams are much softer in the new set. I cut both sets before really thinking about it, but I *probably* should have left the soft ones at their stock width. Pictured are the firmer ones; ~1/4 cut off the width and ~1/4 cut off the thickness on the inside.

I just realized this last night - 1beatjeep made me servo mounts for this truck. He also made mounts for my first TXT back in '05!

Got the servo mounts installed and made links from 5/32 threaded rod, 1/4" OD tube and Revo ends.


Here's a side shot showing the shaved steering stops and slight clearancing for the back of the servo.


And the rear lockout:

Got a 2.5:1 GD600 coming along with some other goodies. That may be easier to mount the 700 motor up to. With a 15T on the motor that'll give me an 85:1 ratio.

Excellent. I feel like it's 2005 all over again. I took my TXT (parts) out of its box two nights ago, to look at it. I spent quite a while reminiscing about my early days of crawling. I had a lot of fun not knowing what I was doing.

Man you ain't kiddin. There's a few differences, but the way I'm going this one is nearly identical to my original TXT!

I originally planned to put battery trays on each side of the chassis, but decided to so with a single TwinForce tray secured to the stock swaybar that's mounted on the upper links. It might not need it but I'm thinkin about feeding the motor with 7 cells of 5000mah. Haven't quite figured out where the electronics box is going.

Here's a mandatory flex shot:



Last night I trimmed the body and prepped it for paint today:

The front tires with the hollow lugs will definitely hook better than the rears, which works out good to keep the front pulling
I couldn't resist the urge to grab my old laptop and go back in time looking at old pics and vids of mine

Good news is the GD600 came; got the shaft turned down and tweaked things so 75% of the motor sits below the top frame rails. It's off-center but not bad at all. Bad news is while drilling a hole I managed to damage two teeth on the main GD600 gear, so I get to buy a new one.
