Radio-Controlled (RC) Model Parts & Accessories Price Comparison 2026
Compare 622 RC model parts & accessories — servos, motors, ESCs and more — from Hobbywing, Spektrum, Tamiya and Traxxas at the best UK prices.
RC model parts are a world unto themselves. Whether you're rebuilding a battered Traxxas after a rough bash session or upgrading a Tamiya touring car for club racing, finding the right component at the right price can make the difference between a weekend on the track and a weekend on the workbench. We've catalogued 622 parts and accessories across the full spectrum — from consumables like tyres and adhesives to high-ticket items such as Spektrum receivers and Tamiya truck controllers that push well past 137 £.
Hobbywing dominates our catalogue with the largest product count, and for good reason: their ESCs and motor combos have become the de facto standard for bashing and racing alike. Spektrum sits at a higher average price point, reflecting their focus on precision receivers and radio systems aimed at serious hobbyists. Meanwhile, complete RC models and their parts often share components — so it's worth cross-referencing if you're building from scratch rather than upgrading.
The price spread here is genuinely wide. Small consumables from Deluxe Materials and ZAP adhesives start from 5 £, while at the other end, full Tamiya truck controller units and Spektrum telemetry receivers can reach into the hundreds. The sweet spot for most upgrades — a quality servo, a replacement gear set, or a decent LiPo — sits around the 17 £ mark. That's where brands like Savox and ARRMA offer solid value without cutting corners on materials or tolerances.
One thing worth flagging: compatibility is everything in this hobby. A servo that's 1mm too wide, a connector that doesn't match your ESC, or a gear ratio that fights your motor will cost you more in frustration than the saving was worth. We'd always recommend double-checking chassis fitment and voltage ratings before committing. Our scale model parts section is also worth a browse if you're working on static builds alongside your runners. And if you're sourcing adhesives or finishing materials, arts, crafts & sewing occasionally surfaces useful crossover products like Deluxe Materials' range.
Prices shift regularly — Black Friday and Amazon Prime Day tend to bring the biggest drops on electronics like ESCs and receivers. We track offers daily across UK retailers including Amazon.co.uk, Modelsport, and specialist RC shops, so comparing before you buy is always worthwhile.
How to Choose RC Model Parts Without Wasting Money
With 622 parts listed across dozens of brands, the hardest part isn't finding a component — it's finding the right one. Most costly mistakes in this hobby come down to three things: wrong fitment, mismatched voltage, and underestimating how much the quality of a single part affects the whole system. Here's what actually matters.
Chassis & connector compatibility
Before anything else, confirm the part fits your specific chassis revision and uses compatible connectors. Tamiya, HPI, and Losi all run proprietary mounting standards, and even within a single brand, a Gen 1 and Gen 3 chassis can differ enough to make a direct swap impossible. On the electrical side, check whether your ESC uses Deans (T-plug), XT60, or Tamiya connectors — mixing these requires adapters that add resistance and potential failure points. If a listing doesn't specify compatibility, contact the retailer before ordering.
Servo torque & speed for your application
Servo specs are quoted in kg·cm (torque) and seconds per 60° (speed). For a 1/10 touring car, 6–8 kg·cm is typically sufficient; a 1/8 buggy or truck needs 10–15 kg·cm minimum, and a large-scale crawler can demand 20+ kg·cm. Speed matters less for crawlers, critically for on-road racing. Metal-geared servos like those from Savox cost more but survive crashes that destroy plastic-geared equivalents. Don't over-spec for a casual basher — you'll pay for capability you'll never use.
Motor & ESC voltage matching
This is where expensive mistakes happen. Every motor and ESC has a maximum cell count — running a 2S-rated ESC on a 3S LiPo will kill it, often dramatically. Hobbywing's Quicrun range is clearly cell-rated; Spektrum's systems integrate with their radio for telemetry monitoring. As a rule: match your ESC's voltage ceiling to your battery, then choose a motor KV rating appropriate for your gearing and tyre diameter. Higher KV isn't always faster — it often just means more heat and shorter run times.
Material grade vs. your use case
Aluminium-anodised upgrade parts look great and last longer than stock plastic — but they also transfer impact energy directly to the chassis rather than flexing and absorbing it. For bashing, reinforced nylon or composite parts often outperform metal because they sacrifice themselves before breaking something more expensive. For racing, where crashes are less frequent and weight matters, aluminium and carbon fibre components justify their cost. Deluxe Materials' adhesives and finishing products are a different category entirely — quality here is about bond strength and cure time, not structural rigidity.
Waterproofing & environmental rating
If you run outdoors — wet grass, puddles, damp tracks — IP-rated components are non-negotiable for electronics. IP54 keeps out splashes; IP67 survives brief submersion. Many budget ESCs and receivers carry no IP rating at all, which is fine for dry indoor use but a liability outside. Hobbywing's waterproof ESC variants and Spektrum's sealed receivers cost a little more but save you from a very expensive short circuit. Check the IP rating in the spec sheet, not just the marketing copy.
Availability of spares & long-term support
RC parts wear out — gears strip, bearings seize, tyres chunk. Choosing components from brands with strong UK spares availability (Tamiya and ARRMA are particularly well-supported through Modelsport and HobbyRC) means you won't be hunting obscure eBay listings six months down the line. Pro-Line's tyre range is vast and well-stocked; Spektrum's receiver ecosystem is deep but proprietary. Avoid no-name clones that look like bargains — when they fail, and they will, you'll find no replacement parts and no support.
- Consumables & small parts (From 5 £ to 9 £) : Adhesives (ZAP, Deluxe Materials), small gear sets, tyre inserts, weathering sets, and basic hardware. Ideal for maintenance and finishing work. Don't expect performance upgrades here — this is the running-cost tier.
- The upgrade sweet spot (From 9 £ to 17 £) : Entry-level servos (Savox SC-0254MG+), ARRMA replacement parts, Pro-Line tyres, and basic LiPo packs from Gens ace. This is where most hobbyists spend most of their money — solid quality without premium pricing.
- Serious performance parts (From 17 £ to 137 £) : Quality Hobbywing ESCs, mid-range Spektrum receivers, Tamiya motors, and Savox high-torque servos. At this level you're buying measurable performance gains and genuine durability improvements. Worth it for regular racers and dedicated bashers.
- High-end systems & controllers (Over 137 £) : Spektrum telemetry systems, Tamiya truck controllers, Carson multi-channel transmitters, and premium Hobbywing motor combos. These are specialist purchases — competition-grade electronics or large-scale truck systems. Not for casual use, but genuinely best-in-class for those who need them.
Top products
- Tamiya 54500 Radio-Controlled (RC) model part/accessory Gear set (Tamiya) : The most-stocked item in our catalogue and for good reason — Tamiya gear sets are the benchmark for OEM replacement quality. Straightforward fitment for compatible Tamiya chassis, though verify your specific model before ordering.
- Savox SC-0254MG+ Radio-Controlled (RC) model part/accessory Servo (Savox) : Savox's entry into metal-geared servos at a genuinely accessible price. Solid torque figures for 1/10 scale use, metal gears that survive crashes plastic units won't. Not the fastest servo on the market, but reliability-to-cost ratio is hard to beat.
- Tamiya 54894 Radio-Controlled (RC) model part/accessory Motor (Tamiya) : A quality brushless motor from Tamiya's upgrade range — well-matched to their own chassis and ESC systems. Premium pricing reflects the brand, but fitment confidence is high. Less compelling if you're not already in the Tamiya ecosystem.
- Spektrum SPMAR10100T Radio-Controlled (RC) model part/accessory (Spektrum) : Spektrum's telemetry-capable receiver at the higher end of the price range — justified for competitive racers who need real-time data feedback. Overkill for casual use, but if you're running a Spektrum transmitter already, the ecosystem integration is genuinely useful.
- ZAP PT-02 (ZAP) : A no-fuss CA adhesive that earns its place in every RC toolbox. Not glamorous, but ZAP's thin formula is the go-to for tyre gluing and bodywork repairs. Cheap enough that there's no reason to risk a no-brand alternative.

Frequently Asked Questions
How do I know if a servo will fit my RC car?
Check the servo's physical dimensions against your chassis's servo mount — standard servos follow a common footprint, but mini and micro servos differ significantly. Most manufacturers publish a compatibility list or chassis-specific fitment notes. Beyond size, confirm the output spline count (25T is most common, but Futaba uses 25T at a different pitch to Hitec) and that the servo lead connector matches your receiver. When in doubt, search your chassis model number alongside the servo model on RC forums — the community will have answered it already.
What's the difference between a brushed and brushless motor for RC?
Brushless motors are more efficient, more powerful, and last significantly longer than brushed equivalents — but they require a compatible brushless ESC, which adds cost. For a beginner or casual basher, a quality brushed setup is perfectly adequate and cheaper to replace when damaged. For anyone racing or wanting serious speed and run time, brushless is the clear choice. Most modern RTR vehicles above the entry level now ship brushless as standard, so replacement parts tend to follow suit.
Are cheap no-brand ESCs and receivers worth buying to save money?
Generally, no — and this is the most common expensive mistake in the hobby. Unbranded ESCs frequently lack accurate voltage cutoffs, which can destroy your LiPo battery through over-discharge, and their waterproofing claims are rarely verified. Unbranded receivers can suffer from interference and signal dropout at the worst possible moment. The saving of a few pounds over a Hobbywing or Spektrum unit rarely survives the first failure. Stick to brands with UK warranty support and verifiable CE/RoHS certification.
What LiPo voltage should I use for my RC model in 2026?
Match the LiPo cell count to your ESC and motor's rated maximum — this is non-negotiable. Most 1/10 scale vehicles run 2S (7.4V) or 3S (11.1V); larger 1/8 scale models often run 4S (14.8V). Running a higher cell count than your ESC is rated for will destroy it immediately. Gens ace and Hobbywing publish clear compatibility guides. Also check your battery's C-rating against your motor's peak current draw — an undersized C-rating causes voltage sag and heat, shortening battery life considerably.
Why are Tamiya truck controllers so expensive compared to other RC parts?
Tamiya's large-scale truck controllers (the 56511 and 56523 units) are multi-function systems designed specifically for their 1/14 semi-truck range — they manage not just steering and throttle but also multi-speed gearboxes, lighting systems, and trailer functions. They're essentially purpose-built transmitters for a niche application, which explains the premium price. If you're not running a Tamiya truck, they're irrelevant to you. For standard RC cars and buggies, a quality 2.4GHz transmitter from Carson or Spektrum at a fraction of the price will outperform them in every relevant metric.
How important is the gear ratio in an RC drivetrain upgrade?
Very — and it's often overlooked. The gear ratio determines the balance between top speed and torque. A numerically higher ratio (e.g. 10:1) gives more torque and acceleration but lower top speed; a lower ratio (e.g. 5:1) does the opposite. When upgrading a motor, always recalculate your overall drive ratio to ensure the motor operates in its efficient RPM range. Running a high-KV motor on a tall gear ratio causes excessive heat and poor acceleration. Most manufacturers publish recommended pinion/spur combinations for their motors — follow them.
What's the best way to find RC parts that are actually in stock in the UK?
Use a price comparison tool that aggregates live stock from multiple UK retailers simultaneously — this saves the frustration of clicking through to out-of-stock listings individually. Key UK stockists for RC parts include Modelsport, HobbyRC, and Amazon.co.uk, with Currys occasionally carrying mainstream Traxxas and ARRMA spares. Specialist parts from Hobbywing and Spektrum are more reliably found through dedicated RC retailers than general marketplaces. Comparing prices across these sources before buying can save meaningfully, particularly on higher-value electronics.
