During this week’s 2018 IFMAR ISTC World Championships, held in Welkom, South Africa, Serpent’s David Ehrbar is running a prototype of the forthcoming S110 S4 1/10th formula car. David had his first roll out of the car in China in the days before making his way onto Welkom for the race. Officially still a prototype, it was finished just the night before he arrived to test in China, the car is the basis for their upcoming kit release which will be known as the F110 S4. Key features of the car are a new rear wing mounting system which is now mounted to the main chassis plate and not to the pod as before. The car has also moved away from using side links to using bearings which David says makes the car more linear especially when cornering and accelerating at the same time.

ArndtCraft have introduced their new Extreme Cool fan shroud for the Yokomo BD8-2018 and 2017 touring cars. The part is purpose designed for the BD8 and uses a standard 30mm fan such as the ones from ArndtCraft, R1 or WTF. The outlet will improve motor cooling when running indoors or in high ambient temperatures and it is compatible with ArndtCraft’s High Velocity inlet for even greater cooling performance.
Following a first set of teaser images ARC have released more information on their new R8S 1/8th stock pan car kit. Developed for the growing class of “rigid”, suspension-less stock 1/8th electric pan cars, the vehicle builds on a carbon fibre main chassis plate with a floating front end and a chassis-mounted, rigid rear suspension. The front suspension utilises O-rings to absorb bumps while providing more controlled cornering with different O-ring hardnesses allowing to fine-tune the steering characteristics. The suspension geometry is adjustable in terms of caster, camber and track width while the steering allows to use different Ackermann setting, again in order to adapt overall steering behaviour. The transmission is made up using a single high-torque belt and it uses large diameter hard-anodised aluminium belt pulleys and and a spur gear adapter that accepts the 1st gear main gears of the R8.1 nitro car – ensuring for swift and easy gear ratio changes. In order to suit a variety of needs, the car is usable with almost every battery configuration imaginable, be it a 4S brick pack or dual 2S batteries mounted in laydown of back-to-back configuration, while the car also takes 2S shorty packs to reduce overall weight and lower the centre of gravity. The R8S will accept all standard 1/8th on-road body shells and tyres and it will hit stores this August.
Coming from Mugen and made for their MRX6R 1/8th on-road car is a carbon fibre radio plate stiffener. The V-shaped brace connects the front bulkhead with the steering bellcrank which results in reduced front end flex and thus greater stability and steering precision when running on high-grip tracks. Using the part will also make steering reaction more consistent. The part is made from high-quality carbon fibre and a direct fit.
Yeah Racing have introduced a power switch extension for the Traxxas TRX-4 trail truck that does away with the need to take the body off in order to reach the on/off switch. The extension lever tucks neatly underneath the rock slider and will not come into contact with rocks for accidental power downs while still allowing for an easy reach. The set is a direct fit for the standard TRX-4 truck and it is available now.
RCLabHK have announced the soon release of their new carbon fibre main chassis kit for the Tamiya TA07 touring car. Designed for low to medium traction outdoor tracks the chassis will improve the car’s overall performance in demanding track conditions. The chassis is set for a release in September.
Coming from Motiv is their new PowerBrick 60, a 12VDC/60A power supply. The device is an in-house modified server supply unit and it features a new Motiv vinyl wrap and red guard. It is also an AutoRange unit, this means it is able to take input from 100VAC to 240VAC all around the world.
VRP has just released their newest piston for 1/8th vehicles, the XV3 HT High Temp. The reasoning behind the HT version of the company’s popular XV3 piston is to be able to run shock oils in the normal 30wt-40wt range during the hot summer months. By installing the new XV3 HT, drivers can instantly drop oils 10wt from where they were before and tune from there. VRP will offer the new HT piston in 6×1.3 and 8×1.3 versions for all the popular vehicles. All are CNC-cut and hand-drilled for accuracy.
