Build a scale from a Tamiya 58397 Toyota Hilux Hight Lift – Part 1 : The chassis

Tamiya 3 speeds Hilux Mountaineer

In 2007 Tamiya release a brand new chassis with 3 speed transmission. A great model for the fans, but instead of putting ugly decals and four ridiculous wheels to create the High-Lift, they should have looked to the past and be inspired by the toyota mountaineer.

That why the first life of my  kit was a replica of the Toyota Mountaineer 58111.

My High Lift, the Tamiya Mountaineer tribute

Here it is in video:

After driving and appreciated an Axial Jeep Rubicon as a “Scale”, I wanted to modified this Toyota as a real 4×4 truck.
This is how I did !

Start of operations

The front drivetrain:

Fist of all I reduce the height by removing the shims between the leaf spring. I buy Super Lift damper which they are 20mm longer. They are also screwed at lower place

The front shock stay are also longer. The steering knuckle are reversed and the steering servo put at the front.

My modifications :

The body is to high due to the transmission and motor. I changed the location with an home made plate cut in carbon fiber.

I stand back the transmission, put a 48dp spur gear with only 75 teeth to minimize the height of body

58080 Tamiya Astute

Tamiya releases the Astute in 1989. The first tamiya buggy where you can beginning to race with. This 2wd was designed to obtain great performance.

Ball differential, suspension adjustment, low profile tires, FRP chassis, roll bar, bell crank steering, everything is present to compete.

Tamiya has develop a new technology for the rear drivetrain. The Z point suspension as named, permit to increase toe -in when the damper is compressed.

The ball differential can be adjusted by adding spacers, there is no spring in outdrive like usual.

diffA clever idea from engineers was to create a door below the transmission gear case to facilitate access to the differential through a hole in chassis.

All electronics are planted in right place (for a competition buggy) and well protected thanks to the body and his under cowl

Even if others manufacturers use ball cup, Tamiya  ajust the upper links with bushing.

I didn’t have the time to drive this freshly refurbished buggy by me. Someone bought it before I put the wheels on track!

Moreover, I remembered when I was a kid and beginning RC with my Tamiya Falcon, my neighbor was offered for his birthday an Astute with Futaba Attack radio.
He was the “king of the hill” with that car, it look so much modern compare to my Falcon. Fast and silent, the low ground clearance and lack of roll was impressive in the park.

After few years, I bought his used Astute and make some run with it on a backyard track. The car wasn’t so impressive on  my bumpy track, turning without understeer was really hard.
All the weight is concentrate at the rear. and the front drivetrain were totally overwhelmed.

Although I keep good memories, the Z-Point suspension and bushing in links were not really a good innovation. As you can imagine it was not a success and racers easily swapped them with Tamiya Madcap parts to obtain a rear drivetrain without play in assembly.
