Update on Gizmo GZ1 – 2017 Parts

A lot of you have requested that I post more about the Gizmo GZ1, which I built and run last summer.

It was always my intention to run the car more and keep you readers updated, but unfortunately some small but important Gizmo specific parts failed, and I needed those to be able to run the car. And with Gizmo ownership changing and it all moving to the US, things simply dragged on and it took a lot of time for me to get those parts.

Luckily I was able to get the car running late this winter and have run the original car a fair bit on carpet while I had access to a carpet track until the end of February. The car really impressed me again, being just as fast as my 419X as soon as I put it on the track.

During this time the Gizmo GZ1 2017 model was released, so let’s take a look at some of the new parts here.

The major re-designed part on the 2017 version is the upper-arm system. This is included on the GZ1 2017, and also availabe as a set to upgrade the original car. The way the upper arm was realised on the original GZ1 made it quite fragile, meaning you had to constantly check and adjust. The 2017 re-design was done to eliminate this.

Below you see the part included with the 2017 upper arm set.


As you can see it is a fairly extensive kit and includes many parts, replacing the upper arm with a two turnbuckle setup. The thickness of the carbon inner plates is increased making them more rigid, also helped by removing the sliding caster adjustment function. Caster is now set by changing the lengths of the two turnbuckles. The plates have two holes allowing upper arm length adjustment.

The new steering arm plates, which attach to the uprights, include holes where you can attach steering limiters to limit steering throw.


The upper arm setup is the same front and rear.


In the picture below you can also see the new for 2017 side plates, which have a slightly changed shape and the option to run two more posts between them if you wish.


The steering rack on the 2017 car has a carbon fibre stopper, adding reliability to the steering system.

Also available as an option are new lower damper towers front and rear, allowing you to use short dampers.


The 2017 version also used a wider front foam bumper for better protection.

TRF Report TITC 2017

Thailand International Touring Car Championship (TITC) 2017
February 16th – 19th, 2017
Infinity Addict Circuit, Bangkok, Thailand

Last month, Thailand played host to TITC 2017. One of the largest R/C events of its kind in Asia,it was held at the impressive Infinity Addict Circuit, conveniently located just 30km from Suvarnabhumi Airport.  279 drivers took part across 6 classes: FF; Formula; Non-Boost; Tamiya Super GT; Open Brushless; and Modified Touring. Tamiya Racing Factory (TRF) team member Takayuki Kono was in attendance to offer advice and answer questions from Tamiya fans and drivers. He also found the time to get on the track, joining in the Tamiya Super GT and Open Brushless classes. Reports follow.

Tamiya Super GT Class

This class featured Tamiya TT series chassis and Super-GT car bodies;
its rapidly growing popularity at domestic races in Thailand led to its inclusion here.
Laps under 27 seconds were discounted in order to make the race a challenge to drivers of all levels.

Kono was eager to try his hand at this class, which was a new experience for him. Using an un-tuned machine, in the Finals he nonetheless put in some sub-27 second laps, which while proving his speed had to be discounted and led to a final finishing position of 8th.
This innovative rule gave all drivers a fair chance and led to great excitement on the track with the victor unknown until the last.

Open Brushless Class

This class featured the most Tamiya car entries,
and Kono himself took part to make sure he was in the best position to advise Tamiya drivers on setup and the like.

His TRF419X machine was fitted with upcoming option parts and provided a great opportunity for him to test them in the heat of action – many were also tested by local Tamiya drivers,their feedback to be added into the mix during further parts development.
Among the success stories were Item 42310 37T Aluminum Differential Pulley,which contributed to significant acceleration and cornering improvements.

Kono achieved a third-place finish in the class, but just as importantly,
he was privileged to have been able to contribute to the amiable atmosphere at this successful event.
