In the year XII – Xray XII 1/12th scale

Middle
Moving to the middle of the chassis we pass the supplied servo saver that offers different mounting holes for the steering ball joints to adjust the Ackermann angle of the steering. Supplied with the kit is also a small bag of shims to fine tune the steering department. The servo saver is free of slop and usable for all common types of micro and mini servos thanks to different sized inserts.

The servo itself is mounted in composite servo posts that anchor in the carbon chassis. The chassis plate feature two different mounting positions. One for micro and one for medium sized servos. The positions differ by 4mm so you should be able to use most of the current ‘1/12 scale’ servos from KO Propo, JR/Graupner and others. With the JR/Graupner DS3781 we where lucky to see that the servo arm located in the middle of the chassis just perfect.

Leaving the steering assembly behind we come to the integral part of every on-road pan car: the T-bar. Having its roots in the early days of electric on-road racing the T-bar is still the most popular method of controlling the roll of a pan car chassis. Ok, to be honest: It seems that the link chassis cars become more and more popular but we come back to that when we get our hands on one!

Back to the XII. The T-bar is made out of 1.5mm thin glass fibre and is called the ‘wide’ carpet spec version. Knowing Xray we are sure asphalt spec versions etc. will follow soon to help adjusting the XII to any kind of track and driving style. The T-bar is equipped with two different locations holes for the tweak screws to allow for an easy adjustment of the hardness of the item. Screwing the grub screws in the front holes makes for a softer feeling T-bar (and an easier to drive car), the rear location holes give a harder T-bar and thus a more responsible ride.

As a very unique feature the XII offers a ‘Club Racing’ option for the T-bar assembly. This is in fact a plastic part that is used instead of the front pivot ball making it nearly impossible to build the car with a ‘tweaked’ T-bar because the usually used tweak screws to not come into play. We haven’t used this option yet but believe that it could be a nice feature for part time racers as tweaking a car can be time consuming and sometimes frustrating …

Above the T-Bar the oil filled damper can be found. It features an all alloy shock body, volume compensation and a two hole shock piston. Supplied in the kit is a rather soft shock spring (13mm diameter) and 350cst oil. Spring preload as well as droop can be adjusted via knurled nuts.
