This is my entry to the model Tamiya should have made contest.
Well at long last this project is done. Started off with the idea of making a modern 3 speed (like the old Hilux/Blazer and Bruiser/Mounty) using only modern Tamiya parts . I wanted a scale truck with the following features: metal frame chassis, solid axles, leaf spring suspension, scale body and a three speed transmission with built in transfer case (2WD to 4WD). I have fulfilled all of those requirements with this truck. I additionally wanted servo controlled locking diffs and full working lights, but for now I have left those two features out.
Just to recap the build, I only used modern Tamiya parts for this project (with a few handmade by myself).
The axles are from a TLT. I started out with open diffs front and rear, but since running it a few times I have changed that. Now I used an encapsulation compound in the diffs that is very thick and sticky and doesn't dry out.
The suspension, linkages, wheels, tires and frame were from the 1/14 semi truck line. (Should be noted that the tires were modifed for a shorter sidewall.) I started this whole project with a Merc 1838, but in the end didn't use anything specific to that truck. The frame rails I ended up using are actually from the Globeliner truck (shortened a bit).
The body is from the Juggernaut with custom flares made from Blackfoot flares. I used pieces of styrene to fill in large gaps, and auto body filler for the rest. I know it's not exactly how it looks on a real dually, but for the sake of my sanity, this is as close as it gets.
The 3 speed tranny with transfer case was designed and built by myself. I used mostly parts from Tamiya's 1/14 semi tranny and belt drive from TLT. Shifting is done on the radio just like the old 3 speed trucks. Although since this is a constant mesh design, it can shift smoothly on the go. First gear is 4WD while second and third are 2WD.
The drive shafts are from the CC-01 chassis. I believe I used two of the longer type and ended up having to trim both of them.
The total build time was about six months, and the total cost of all the parts and electronics was around $750.00. So there you have it. Let me know what you think.
