RC racing gear guides, built on the rules of the class you race.

How we recommend

Our picks are categories of RC racing gear, such as off-road buggy kits, radio transmitters or pit mats, never particular models or brands. Each pick says who it may suit and which rule bears on it, with the body, the document and its edition or date. We do not publish hands-on reviews, we do not rank products, and we do not quote or compare prices. The buttons take you to current listings so you can compare for yourself. Product links are affiliate links, and we may earn a commission at no cost to you; that never decides which categories we include.

Nothing in these guides says a car, battery, charger, engine, fuel or transmitter is legal, compliant, approved, certified or safe. Each time, the guide names what decides instead: the rule book and approved lists of the body running the event, the track, the race director, and for radios and travel, the regulator of the country concerned.

Four things decide before any purchase

• The class's rule book. Each body writes its own, and they are never merged here. IFMAR writes a separate World Championship rule book for each discipline; EFRA publishes a yearly Handbook (the 2026 Appendices 3 and 4 cover electric cars, batteries and motors); ROAR publishes its own rule book, which this site could not read, so ROAR appears only through its dated announcements. The BRCA's 2026 section rules were not read either.
• The body's approved lists. EFRA's 2026 Appendix 4 (section 2) says only batteries shown on EFRA's official website are legal at its events. ROAR's rule book update of 18 October 2024 (rule 8.14.4.1) makes it the driver's responsibility to know whether their motor, battery, speed controller and body are on the most recent ROAR Approved List. A category in these guides is never a substitute for that list. See approved equipment lists.
• The track and the race director. EFRA's 2026 Appendix 3 (A 5.2 to 5.8) says the race director has absolute authority at the meeting. At IFMAR's 1/8 IC off-road World Championship each driver signs a form at registration accepting the event's published rules (2024 rules, 3.24.e), and ROAR's National Guidelines (revised 13 October 2026, 4.5.11) require the race flyer for a National to state that racers will abide by the decisions of the race director or ROAR officials and by the ROAR rules.
• The law of the country. Racing rules leave radio frequencies to the host country: IFMAR allows 2.4 GHz and crystal systems only as permitted in the organising country (1/8 IC off-road 2024, 3.25), and ROAR's guidelines allow only FCC-legal frequencies at its Nationals (5.4.3). Batteries carried by air come under air-transport rules such as IATA's guidance of 31 March 2026, which IATA itself says is guidance only and not a source of regulatory compliance.

What these guides keep repeating

• No gear is prevention. No battery, charger, sack, case or bumper is presented as preventing a fire or an injury. EFRA and IFMAR rules require LiPo sacks at certain times and define them as built to contain a fire; that is the rules' definition, not a finding, and these guides carry no pick for sacks. A battery fire needs the emergency services, and an injury needs medical care. What the hazard rests on (for example a 2023 UL fact sheet hosted by the New Jersey Division of Fire Safety) is set out in the safety section.
• No procedures. No driving technique, building, assembly, setup, tuning, soldering, wiring, engine break-in, fuel mixing or handling, charging, balancing, storage or disposal steps appear in any guide. Those belong with the makers' instructions, a club and the track's own rules.
• Rules per body. Where IFMAR and EFRA disagree, as they do on receiver packs in 1/10 off-road (IFMAR's March 2023 battery rules allow one, EFRA's 2026 Appendix 3 bans them), both versions are given.
• No prices. The guides contain no money figures of any kind.

Where to start

• Starting out? The beginner RC racing kit guide sets out what a class, a body and a club decide before a first purchase.
• Not sure which class? Choosing a class lays out each body's classes side by side without merging them.
• Radio and receiver? The radios guide covers what racing rules and each radio regulator publish, plus servos.
• Batteries? The batteries and chargers guide keeps EFRA's and IFMAR's battery rules apart and points to the travel and hazard pages.
• Tyres? The tyres and wheels guide covers control tyres, colour, additive and warmer rules, and sizes by class.
• Race day? The pit gear guide covers transponders, pit mats, stands, tools and bags, and what the rules say about the pits and marshalling.
• Nitro? The nitro gear guide covers engines, glow igniters and starters by IFMAR's engine and muffler rules.
• Buying a present? The gift guide suggests gifts that do not depend on a class's rules, and explains the age lines that come with a car.

A battery's cell count, voltages and case size can be compared with EFRA's 2026 or IFMAR's 2023 battery limits using the battery rule checker. It does not check approved lists.

How we handle sources

Governing bodies (IFMAR, EFRA, ROAR, FEMCA, FAMAR, the BRCA and other national bodies), radio and transport regulators, product-safety regulators, trade press (attributed) and makers (as claims) are our sources. Where sources disagree, we give each version and who says it. Where a document could not be read, such as ROAR's current rule book, the BRCA's 2026 section rules, EFRA's IC appendices, or the FCC's, Ofcom's, FAA's and PHMSA's pages, we say so rather than fill the gap. Everything here is summarised as of 30 October 2026; the body's current rule book and the organiser's own rules for an event take precedence over this summary.
