Overview

The LOGIC Heat Shrink (1m Clear) 50mm O-LG-HS50 is an essential accessory for any RC enthusiast working with larger cable bundles, battery packs, and electronic assemblies. Whether you're building an RC car, RC boat, RC plane, or maintaining hobby electronics, this heat shrink tubing provides a professional, protective finish that keeps your connections tidy and secure. The clear colour makes it ideal for applications where you need to see the components underneath whilst maintaining full protection against moisture, abrasion, and mechanical damage. This product is supplied as a full 1 metre length of premium quality tubing, giving you plenty of material for multiple projects or repairs.

Heat shrink tubing is one of the most versatile and practical accessories in any RC workshop. The 50mm nominal expanded size suits larger cable bundles, multi-connector battery packs, and significant wiring looms where smaller diameter heat shrink simply won't fit. Whether you're an experienced RC racer, a weekend basher enjoying your RC truck or buggy, or someone just getting started in the RC hobby, having quality heat shrink in various sizes is absolutely essential. Clear heat shrink is particularly valuable because it allows you to maintain visibility of your connections and colour-coded wires whilst providing complete insulation and protection.

LOGIC RC is a recognised manufacturer of electrical components and accessories for RC models across the UK and beyond. The LOGIC Heat Shrink range offers consistently reliable performance with flame retardant properties, low smoke output if burned, and an operating temperature range from -45°C to 125°C, making it suitable for all climates and conditions you might encounter in RC modelling.

Key Features

• 50mm Nominal Expanded Size — This diameter is specifically designed to accommodate large cable bundles and battery pack assemblies where standard smaller heat shrink tubes cannot fit. The inside diameter is approximately 20% larger than the nominal size, meaning the 50mm tube can comfortably fit over cables and connections up to 50mm in diameter without forcing or stretching the material, which could compromise its integrity.
• Clear Colour Option — Unlike the red and black alternatives available in smaller sizes, the clear heat shrink allows you to see your colour-coded wires and connections underneath the tubing. This is invaluable for troubleshooting, maintenance, and verifying correct wire placement during assembly of your RC car, RC boat, or RC aircraft electronics. The transparency means you don't lose visibility of your carefully organised wiring.
• 1 Metre Length — You receive a generous 1 metre (approximately 39 inches) of continuous tubing, providing enough material for multiple applications or to keep spare heat shrink on hand for future projects. This length is far more practical than purchasing pre-cut segments, as you can cut exactly the length you need for each specific application.
• Flexible Construction — The heat shrink tubing maintains flexibility both before and after shrinking, allowing you to wrap it around irregular shapes, bundle different wire gauges together, and conform to the specific geometry of your RC model's electronic components without becoming brittle or cracking.
• Flame Retardant Properties — The material is manufactured with flame retardant additives, providing an important safety feature in case of electrical fault or short circuit. This is particularly important when working with high-energy LiPo batteries commonly used in RC cars and RC planes, where fire safety is a genuine concern.
• Low Smoke Output if Burned — In the unlikely event of a thermal incident, this heat shrink produces minimal smoke compared to standard plastic tubing. This reduced smoke output is important for both safety and protecting your expensive RC equipment from smoke damage, and it reflects the premium quality of LOGIC RC materials.
• Wide Operating Temperature Range — The tubing maintains its properties across temperatures from -45°C to 125°C, meaning it will perform reliably in cold winter conditions when using your RC models outdoors in the UK, and equally well in hot summer weather or near heat-generating components like brushless motors and electronic speed controllers (ESCs).
• 3:1 Shrink Ratio — When heated to the shrink temperature of 125°C, the 50mm tubing will recover (shrink down) to approximately 17mm diameter, creating a tight, secure fit over your cables and connections. This dramatic size reduction provides substantial compression that holds everything firmly in place whilst creating an effective moisture barrier.

Technical Performance

The LOGIC Heat Shrink tubing represents premium quality in cable management and electronic protection. The material is engineered specifically for RC applications, where reliability under demanding conditions is non-negotiable. The 50mm size sits at the upper end of the heat shrink range and is perfect for larger battery packs used in 1/5 scale RC trucks, multi-connector assemblies found in RC boats and amphibious vehicles, and substantial cable bundles in scale RC aircraft. The nominal expanded size of 50mm means the internal diameter is approximately 10mm larger, so it slides easily over cables and connectors without requiring force that could damage delicate soldering or connector pins. Once heated to the shrink temperature of 125°C (which can be achieved with a heat gun, heat source, or by careful use of a soldering iron tip), the tubing contracts to approximately 17mm diameter, creating a compression ratio of roughly 3:1. This dramatic reduction means the heat shrink grips your connections with significant force, preventing any movement whilst creating an excellent seal against moisture ingress. The lay flat width of the 50mm tube is approximately 78mm (internal diameter multiplied by 1.57), which is useful to know when planning how to wrap batteries or bundle multiple wires. Materials are selected for durability, with flame retardant additives providing important safety characteristics. The -45°C to 125°C operating range ensures reliable performance in all UK weather conditions and working environments, from winter RC racing events in Scotland to summer bashing sessions in the garden. The low smoke characteristic if burned reflects the quality of the polymer formulation and provides peace of mind when working with high-energy electrical systems.

Frequently Asked Questions

• What size heat shrink do I need for my RC model? — Heat shrink tubing size is quoted as nominal expanded (pre-shrunk) diameter. The 50mm size suits large cable bundles, battery pack overwraps, and substantial connectors. For reference, the inside diameter of the 50mm tube is approximately 20% larger than its nominal size, so it can fit over cables up to around 50mm diameter. When heated to 125°C, it shrinks down to approximately 17mm diameter with a 3:1 shrink ratio. If you need guidance on which size is right for your specific application, the LOGIC RC size guide explains the lay flat width calculation and shrinking characteristics.
• Can I use this clear heat shrink on my RC car battery pack? — Yes, absolutely. This is one of the most popular applications for 50mm clear heat shrink. It provides a professional protective overwrap for LiPo battery packs commonly used in RC cars and trucks, holds multiple connector leads together securely, and allows you to see the battery condition and colour-coded balance wires underneath. The clarity also helps when checking for battery swelling or damage.
• How do I shrink the heat shrink tubing? — You need a heat source such as a heat gun, which is the preferred method for even, controlled shrinking. Alternatively, you can carefully use a soldering iron tip or even hold the tubing briefly near a flame (though this requires care to avoid over-heating). The shrink temperature is 125°C. Simply slide the tubing over your cables or connectors, position it correctly, then apply gentle heat whilst rotating the tubing to ensure even shrinking. Allow it to cool before handling to avoid burns.
• Is this suitable for hobby electronics projects? — Yes, this heat shrink is equally suitable for general electronics projects beyond RC models. It's perfect for cable management in workshop electronics, protecting soldered joints, colour-coding cables, and providing mechanical protection for any assembly that might experience vibration or abrasion. The 50mm size is particularly useful for larger assemblies.
• What is the difference between clear heat shrink and red/black heat shrink? — The main difference is colour and visibility. Clear heat shrink allows you to see the wires and connections underneath, making it ideal for troubleshooting and quality checking. Red and black options are available in smaller sizes (2mm to 15mm) and are useful when you want complete opacity or need to colour-code different cable bundles. The 50mm size is available only in clear, which is perfect for battery packs and large assemblies where visibility is often valuable.
• How much cable can I wrap with 1 metre of heat shrink? — That depends on the length of individual applications. With 1 metre of 50mm tubing, you could wrap approximately 2-3 large battery packs, or create 4-5 protection sleeves for significant connectors, or wrap several substantial cable bundles. It's wise to keep extra heat shrink in stock because once you start using it, you'll find applications everywhere in your RC workshop.
• Is LOGIC RC heat shrink flame retardant? — Yes, the material includes flame retardant additives, providing important safety characteristics when working with high-energy electrical systems like LiPo batteries. In the event of electrical fault or short circuit, flame retardant properties can help limit fire spread. Additionally, if burned, this heat shrink produces low smoke output compared to standard plastic tubing.
