AS91744

Overview

The Associated AS91744 B6/B6.1 Brass Under Battery Weights are precision-engineered weight plates designed to optimise your RC buggy's balance and handling characteristics. Whether you're competing at the track or enjoying casual RC car racing in the UK, weight distribution is a critical factor in achieving consistent performance on high-grip surfaces. These brass weights fit neatly beneath shorty LiPo battery packs, allowing you to add mass to your vehicle whilst simultaneously lowering its centre of gravity – a combination that delivers measurable improvements in handling stability and cornering performance.

If you're serious about your RC buggy setup and want to fine-tune your vehicle's handling dynamics, these Associated weight plates are an essential upgrade. The dual-plate system gives you flexibility to experiment with different weight configurations, helping you find the perfect balance for your specific track conditions and driving style. For anyone running an Associated B6 or B6.1 buggy, these weights represent an affordable way to unlock the full potential of your chassis without requiring major modifications or rebuilds.

RC Model Shop stocks genuine Associated components and spares for UK RC enthusiasts at competitive prices. Whether you're a weekend basher or a serious competitor, having access to quality upgrade parts like these brass weights makes all the difference in maintaining and improving your RC buggy's performance.

Key Features

• Under-battery mounting design — These weights are specifically engineered to sit neatly beneath shorty LiPo battery packs, positioning the added mass as low as possible within the chassis to reduce your vehicle's overall centre of gravity and improve stability.
• Dual-plate system with flexible weighting options — The set includes two brass plates weighing 26g (0.02 inches thick) and 43g (0.04 inches thick), giving you the flexibility to use one plate, both plates, or interchange them to dial in the perfect balance for different track conditions.
• Improved handling on high-grip surfaces — By lowering the centre of gravity and adding strategic weight, these plates help your buggy maintain better traction and stability during cornering, particularly on smooth, high-grip racing surfaces where weight distribution is crucial.
• Etched weight identification markings — Each brass plate is clearly etched with its weight specification, allowing quick and accurate identification in the pits without needing to refer to packaging or manuals, saving valuable setup time at the track.
• Premium brass construction — Manufactured from high-quality brass, these weights offer excellent durability and precise weight consistency, ensuring your setup remains consistent across multiple racing sessions.
• Compact, optimised dimensions — Measuring 3.74 inches by 2.08 inches, the plates are specifically sized to fit perfectly under standard shorty LiPo batteries without interfering with other chassis components or battery securing systems.

Technical Performance

The Associated AS91744 brass weight system is engineered with precision in mind, using high-quality brass construction that provides both durability and consistent mass characteristics essential for competitive RC buggy racing. The dual-plate configuration (26g and 43g) allows racers to achieve fine-tuned weight distribution across a range of 0g to 69g total added weight, depending on which plates are installed. The brass material offers superior weight consistency compared to lighter alternatives, and the precise etching of weight markings ensures you can accurately track your chassis weight adjustments – critical data when optimising your vehicle for different track surfaces and conditions. The under-battery mounting position is key to the performance benefit: by placing additional mass low in the chassis, directly beneath the battery, you reduce the vehicle's polar moment of inertia and lower the centre of gravity simultaneously, resulting in improved cornering stability and more predictable handling characteristics on high-grip racing surfaces. These weights are specifically designed for the Associated B6 and B6.1 buggies, ensuring perfect compatibility with both models' battery mounting systems and chassis geometry. The 0.02-inch and 0.04-inch thickness options give experienced tuners the ability to stack and configure weights as needed for their specific setup preferences.

What's in the Box

• One 26g brass weight plate (0.02 inches thick)
• One 43g brass weight plate (0.04 inches thick)

Frequently Asked Questions

• Will these brass weights fit my Associated B6 or B6.1 buggy? — Yes, these weights are specifically designed for the Associated B6 and B6.1 chassis and fit perfectly under shorty LiPo battery packs. They are engineered to integrate seamlessly with your existing battery mounting system without requiring any modifications to your buggy.
• How much weight can I add with these plates? — The set provides two options: a 26g plate and a 43g plate. You can use just the lighter 26g plate for minimal weight addition, just the 43g plate for more significant adjustment, or both plates together for a total of 69g added weight, giving you flexibility to tune for different track conditions.
• Why does lowering the centre of gravity improve handling? — A lower centre of gravity reduces the vehicle's tendency to roll during high-speed cornering, improves weight transfer to the tyres, and provides more predictable and stable handling characteristics, particularly on high-grip surfaces where traction is plentiful and you need to maximise cornering speed.
• Are these weights suitable for beginners or competitive racing? — These weights are ideal for anyone serious about optimising their RC buggy's setup, whether competing at club level or enjoying spirited weekend racing. Experienced tuners will appreciate the precision and the dual-plate system's flexibility, but even casual racers can benefit from improved handling stability.
• Can I use just one weight plate instead of both? — Yes, absolutely. The dual-plate system gives you complete flexibility. You can use just the 26g plate for subtle handling adjustments, just the 43g plate for more significant changes, or experiment with both to find the perfect setup for your specific track and driving style.
• How do I identify which weight is which in the pits? — Each brass plate is clearly etched with its weight specification (26g and 43g), allowing you to instantly identify which plate you're handling without needing to weigh them or check packaging, saving time during track sessions.
• Do these weights work with other battery types or only shorty LiPo packs? — These weights are specifically designed to fit under shorty LiPo battery packs. They are engineered to work with the B6 and B6.1 chassis battery mounting systems and are optimised for shorty format batteries commonly used in competitive RC buggy racing.
