What makes the Corally Ultra V+ stand out from conventional silicone wires is the revolutionary strand construction. At just 0.05mm per strand, the copper strands are significantly thinner than those found in standard silicone wiring, yet there are 70% more strands packed into the same gauge. This engineering breakthrough delivers multiple benefits that matter to serious RC car UK enthusiasts: superior flexibility, the ability to handle higher current loads for the same wire gauge, reduced internal resistance, and critically important—lower voltage drop that keeps your battery voltage higher throughout your run.
Key Features
- Ultra-Flexible Strand Construction — With 1018 individual strands, each measuring just 0.05mm in diameter, this wire is exceptionally flexible and pliable. This extreme flexibility makes routing the wire through tight spaces in your RC model much easier, and means the wire won't fight against your components or restrict movement in your motor pod, which is crucial for optimal performance on competitive race courses and casual driving alike.
- 70% More Strands Than Standard Wire — The Ultra V+ packs significantly more copper strands into the same AWG rating compared to conventional silicone wires. This increased strand count directly translates to better current-carrying capacity without increasing wire diameter, and more importantly, it dramatically reduces internal resistance for cleaner power delivery to your motor and ESC.
- Lower Internal Resistance — The ultra-thin strand design combined with the higher strand count results in substantially lower internal resistance compared to standard silicone wire. This engineering feature ensures that less power is lost to heat generation in the wire itself, which means more usable power reaches your brushless motor or brushed motor system for faster acceleration and higher sustained speeds.
- Reduced Voltage Drop — Due to the lower internal resistance, the Corally Ultra V+ maintains a higher voltage at your motor terminals compared to standard wires of the same gauge. This voltage preservation is critical for RC racing where every volt counts in competitive situations, and it ensures your battery's stored energy is used more efficiently rather than being wasted as heat in the wiring harness.
- Pre-Tinned Copper Conductors — The copper strands are factory pre-tinned, which makes soldering connections to connectors, ESCs, battery packs, and receivers significantly easier and more reliable. This feature saves you time during setup and reduces the risk of cold solder joints that could cause intermittent electrical faults or complete loss of power during a race or run.
- Ultra-Thin Silicone Insulation — The silicone insulation layer is thinner than that found on standard silicone wires, without compromising safety or durability. This thinner insulation contributes to the overall flexibility advantage whilst maintaining the excellent heat resistance and electrical safety properties that silicone provides.
- 14 AWG Rating with Enhanced Performance — Rated at 14 AWG (2.08mm² cross-sectional area), this wire provides excellent current-carrying capability suitable for high-performance RC applications including brushless systems, ESCs with high current ratings, and LiPo battery packs. The 14 AWG rating offers a good balance between current capacity and flexibility.
- Compact 3.5mm Outer Diameter — With an outer diameter of just 3.5mm, this wire is relatively slender compared to some thicker silicone wires, making it ideal for routing through tight spaces in modern compact RC car designs, especially in pan cars where every millimetre of space in the motor pod matters.
- 1 Metre Supply Length — Each roll provides a full 1 metre of wire, giving you ample length for multiple connections, custom harnesses, or replacing damaged wiring on your RC model. This length is sufficient for most single vehicle projects and wiring installations.
Technical Performance
The Corally Ultra V+ Silicone Wire represents a significant engineering advancement in RC power distribution technology. The key to its exceptional performance lies in the revolutionary strand configuration: 1018 individual copper strands, each at a microscopic 0.05mm diameter. This construction method is fundamentally different from conventional silicone wires, which typically use thicker, fewer strands. By using many more thinner strands, Corally has created a wire that exhibits near-liquid flexibility whilst simultaneously improving electrical performance characteristics that directly impact your RC car's speed, acceleration, and power consistency.
From a materials perspective, the wire features high-quality, pre-tinned copper conductors that form a 2.08mm² cross-section (14 AWG equivalent), providing robust current-carrying capacity without excessive bulk. The silicone insulation is specifically formulated to be thinner than standard alternatives, which reduces the overall wire diameter to just 3.5mm outer diameter whilst maintaining superior heat resistance and electrical safety ratings. This is particularly important when working with modern brushless motor systems and high-discharge LiPo batteries that demand reliable power delivery without voltage sag. The internal resistance of this wire is measurably lower than standard 14 AWG silicone wires due to the increased surface area provided by the additional strands and the superior conductivity per strand. For RC racers in the UK and internationally, this reduced resistance means voltage sag is minimised during high-current demands, keeping your brushless motor running at optimal RPM throughout your run. The pre-tinned construction ensures excellent solder joints, eliminating the risk of poor connections that can cause resistance build-up at connection points. Whether you're wiring a competition-level 1/10 scale buggy, a 1/12 scale pan car, or any other RC vehicle requiring serious electrical performance, the Ultra V+ delivers measurable improvements in efficiency and reliability.
