Reds Racing have introduce their new generation of nitro GT engines called the 521 GTS. The new engine, available in steel or ceramic bearing versions, features high reliability, tuning stability and great fuel mileage, combined with specific technical changes in the porting and new materials. This 5 port engine claims to offer higher power and better fuel efficiency compared to other engines. The S line features a new and unique high stiffness crankcase design and uses all new materials and casting technology. The engine is produced with pressure die casting, which is a very high quality process, while previous generation R line crankcase was with gravity casting. Another big improvement is the brand new aluminium carburettor, again made using pressure die casting. The decision to change carburettor materials from plastic to aluminium further improves idle stability and tuning. The new carburettor is 30° inclined for better fluid dynamics to increase engine power and has an insulator to reduce carburettor temperature and increase idle stability at high temperatures.
Yeah Racing have created this true oil filled gear differential for Tamiya’s TT02 and TT01. Using a design based on 1/10 competition touring car differentials to ensure smoother operation and with a proper seal, it comes with driveshaft blade protectors to protect the driveshafts and differential outdrives. This will only work with the small sized ball joint universals.
For the F1Ultra, Exotek have produced this new optional extra stiff chassis designed for extra high grip smooth tracks. Made in the USA from 2.5mm quasi weave carbon fibre there is now also a new extra short wheel base setting (2mm shorter than the stock short wheelbase) and there is an extra chassis hole for 1/12 servo mounting. Also for the same car is a heavy duty steel ball diff axle. The 1-piece shaft offers maximum durability and also provides extra rear weight (shafts weighs ~26grams) for more traction in low grip conditions. Solid on the right side and hollowed on the left side to help balance the rear pod, the alloy diff ring mount is a direct fit for the F1Ultra stock ball diff.
H2 Racing Development have introduced these new direct spool cups for the Tamiya TRF420. If you have problems with your kit spool cups breaking this ne version is more rigid than the original aluminium and steel cup. Made with 7075 aluminium alloy with anti wear coating it is a direct replacement for the original and has minimum play in between the universal joint ball head and shaft cap. Weighing less than 2 grams per piece, they are sold as a pair.
From Arrowmax and made for their honeycomb line of aluminium chassis is this fully adjustable battery holder. The shorty battery holder is made from tungsten copper and weighs a total of 90g. This adjustable weight is simple and easy to move forward and backwards with multiple mounting holes available. It is designed to keep the CG as low as possible and it is recommended for carpet tracks and small outdoor asphalt tracks.
Grand Prix 3D are offering a fusion of historic Grand Prix, RC racing and scale modelling, all in one. This electric 1/10th scale RC car has been developed true to the iconic Grand Prix cars of the 1960’s era with scale details throughout, including engine, exhausts, gearbox, suspension, steering, driver figure and more. In what is a very clever design that manages to seamlessly integrate the electronics, the motor and drive train are mounted inside a scale looking engine and gearbox with the steering servo, ESC and receiver in the footwell of the car. Using a majority of 3D printed parts, printed with carbon fibre and glass fibre reinforced nylon, it does also feature a rear gear differential, period authentic CVDs, full ball bearings and scale body shell. Currently set for a release in February next year, they are taking pre orders on their website.
New for the Execute XQ10, Xpress have released this high flex chassis. Designed for use in low grip conditions, it will increase drivability as this chassis will generate more mechanical grip at the expense of some corner speed. Machined from 2.25mm thick carbon fibre.
R1 Wurks have released this 10,000mAh 130C 2S Graphene battery. Aimed at those needing the absolute highest power, this pack is focussed towards the drag racing segment where the high capacity equates to lower voltage drop under load. This in turn allows you to cool down and do multiple runs and expect close to consistent times.
