Arrowmax is the latest company to announce the release of mid-motor conversion kits for the popular Xray T4 and Yokomo BD9 touring cars. The Medius called kits base on 2.25mm US weave carbon or 2.0mm machined aluminium chassis with 2.0mm carbon fibre upper decks and they utilise redesigned single-piece 7075 alloy motor mounts and centre pulleys. Included with the kits also come chassis stiffeners that allows to adjust chassis flex to suit current track conditions or driving styles. Arrowmax promise increased cornering speed, traction and steering in addition to improved ease of driving. The kits are meant to ship by the end of the month.
Infinity has released a set of high-precision 4.9mm titanium ball ends for their IF14 1/10 electric touring car. Offering an approximate 8g – or 47 percent – weight reduction compared to the kit’s standard steel ball ends, the polished finish of the ball surface ensures smooth movement over long periods of use. Supplied as a kit of 20 pieces, each of the sizes – short, medium and long – are available separately as a pack of four.
Hobbywing have introduced their new XeRun XR10 Pro 1S Heavy Duty brushless speed controller specially designed for competition 1/12th scale racing. New internals allow for greatly improved heat dissipation even when using low-turn modified motors or when racing in high ambient temperatures while a built-in switch and capacitor module keep wiring as clean as possible while also saving weight. The controller features five pre-set profiles for all sorts of racing conditions, however they can be customised using Hobbywing’s optional WiFi Module and an iOS or Android-based mobile device or a programming box. The internal BEC system with 6V/3A output does away with the need of a separate receiver battery and adjustable throttle and brake PWM frequencies ensure precise throttle and brake control especially in Stock motor classes.
The third and final round of this year’s Xray Racing Series Alpe Adria was held at the Fener track in Italy.

In the end it was local hero Mattia Collavo with the overall TQ in the premier 1/8th IC Track class, in front of large scale European champion B.A. Arnaldi and 1/8 EC-B finalist Nejc Mihelic. The 1/8 GT pole sitter was Luciano Bordin in front of Antonio Pucci and Michele Finato while in Super Touring.

Rebellion-RC have released more teaser images of their forthcoming mid motor conversion kits for the Xray T4, Yokomo BD9 and BD8 as well as the Team Associated TC7.2. The kits centre around the patent pending sliding motor mount design that allows gear mesh adjustment through the chassis bottom, with the narrow design of the whole assembly ensuring the overall motor and battery width remains the same as in the standard cars, creating a very centralised weight distribution and less unwanted chassis roll compared to current mid motor conversions. In addition the design makes for an ultra low centre of gravity while allowing integrated flex settings. The sliding design also ensures a very wide gear mesh adjustment range, fitting up to 48T pinion and 114T main gears, making the conversion ideal for both stock and modified racing alike. Other features include a highest quality PA12 material 3-D-printed diff pulley that is precision CNC-milled for a perfect finish, a precision-machined stainless steel main shaft as well as the possibility to combine all three aluminium colour options of black, orange and natural with Rebellion-RC’s full range of carbon fibre twill colours. Not to be forgotten is a floating motor fan mount that attaches to the motor mount and that ensures lower motor temperatures while not disturbing natural chassis flex. Included with the kits, that are completely made in Austria, also come high-quality Bando Kevlar belts as well as all needed screws and bearings. The conversions are available for pre-order now and they will become available by August 1st.
