Head-to-Head: Losi 5ive vs X-Maxx Across Every Key Metric

Size and Physical Presence

The Losi 5ive-T 2.0 is genuinely larger. At 1/5 scale, it dwarfs most other RC trucks, including the X-Maxx which is technically around 1/6 scale (though Traxxas doesn’t officially assign it a scale rating). If you want the absolute biggest presence on the bash field, the 5ive wins. Its 22+ lb frame is imposing and realistic in a way that turns heads at any bashing session.

Speed and Performance

Interestingly, the X-Maxx actually wins on top speed despite being smaller. On a full 8S LiPo setup, the X-Maxx can exceed 50 mph. The Losi 5ive tops out around 35 mph with its 32cc gas engine. However, speed isn’t everything — the 5ive has exceptional torque from its gas motor that produces a different kind of driving feel entirely. For learning to manage speed and build driving confidence, you might also enjoy reading our guide on how to change the speed of an RC car.

Maintenance Requirements

This is probably the biggest practical difference. The X-Maxx is relatively low-maintenance — charge batteries, check hardware, go bash. The Losi 5ive requires regular engine maintenance: air filter cleaning, fuel line inspection, carb tuning, plug checks, and the all-important break-in period. If you enjoy working on vehicles, the 5ive is incredibly satisfying. If you just want to drive, the X-Maxx wins easily. Upgrading either truck down the line will require solid tools — our guide to the 10 best RC car tools for maintenance is essential reading before you start wrenching.

Running Costs

The X-Maxx’s biggest ongoing cost is LiPo batteries. A quality 8S LiPo pack for the X-Maxx typically runs $80–$150 each, and you’ll want two or three for a decent session. The 5ive runs on 91+ octane pump gas, which is far cheaper per session — you might spend $5–$10 in fuel for a full afternoon of driving. Long-term, the 5ive is cheaper to run per hour of driving time.

Community and Parts Support

Traxxas has the strongest hobbyist support network in the industry. Parts are available at almost every hobby shop in the US and extensively on Amazon. Losi has excellent parts availability too, but it’s slightly less ubiquitous. Both have active online communities, but if you crash far from home and need a part urgently, the X-Maxx is more likely to be locally supported.

How to Get Started With Your Losi 5ive or Traxxas X-Maxx: Setup Guide

What You’ll Need

• Traxxas X-Maxx 8S RTR or Losi 5ive-T 2.0 RTR
• 8S LiPo battery packs (for X-Maxx) or 91+ octane fuel (for Losi 5ive)
• Dual LiPo battery charger
• Hex driver set for assembly checks
• Blue Loctite threadlock for securing hardware
• Shock oil set for suspension tuning
• LiPo safe storage bags (critical for battery safety)

1. Unbox and inspect all hardware. Before your first run, go over every visible bolt and screw. Large RC trucks take vibration hard — loose hardware is the #1 cause of early damage. Apply blue Loctite to critical fasteners.
2. For the X-Maxx: Charge your LiPo batteries correctly. Never charge unattended, always use a quality balance charger, and store at storage voltage when not in use. Read our LiPo battery storage voltage guide to protect your investment.
3. For the Losi 5ive: Perform the engine break-in. This is non-negotiable. Run 3–5 tanks of fuel rich (slightly richer than optimal) before going full throttle. This seats the piston rings and significantly extends engine life.
4. Set up your transmitter and bind your receiver. Both trucks come with transmitters, but double-check all controls, trims, and endpoints before driving. Understand the role of transmitters and receivers in RC vehicles.
5. Choose your first driving location carefully. These are massive, fast vehicles. An open, flat area free of pedestrians and pets is essential. Avoid concrete and hard asphalt at first — grass or dirt is kinder on components during the learning phase.
6. Start slow and build up. Even if you’re an experienced RC driver, learn how your specific truck handles before going full throttle. The X-Maxx’s TSM system helps here; the Losi requires a more practiced hand at high speeds.
7. Post-run inspection and maintenance. After every session, clean the truck, inspect for damage, recheck hardware, and store LiPo batteries at storage voltage. For the 5ive, drain fuel from the carb if it will sit for more than a week.

Mistakes to Avoid When Buying and Running Large-Scale RC Trucks

• Mistake 1: Not budgeting for batteries. The X-Maxx on 8S needs two 4S packs or one dedicated 8S pack, costing $80–$150 per pack. Budgeting only the vehicle price and forgetting batteries leads to expensive surprises. Fix: Budget at least $200–$300 for batteries and a quality charger alongside your vehicle purchase. Our best dual RC battery chargers guide will help you choose wisely.
• Mistake 2: Skipping the Losi 5ive engine break-in. Running the 5ive hard before breaking in the engine causes accelerated wear and can ruin the engine prematurely. This is the single most common mistake with new gas RC owners. Fix: Follow the break-in procedure precisely. 3–5 careful tanks, rich mixture, before pushing hard.
• Mistake 3: Storing LiPo batteries fully charged. Leaving LiPo batteries at full charge damages cells over time, reduces capacity, and in worst cases creates safety hazards. Fix: Always store LiPo batteries at storage voltage (3.8V per cell). See our complete guide to maximising LiPo battery lifespan.
• Mistake 4: Running without checking hardware first. Vibrations at high speed loosen screws rapidly on large-scale trucks. An un-noticed loose wheel hub or suspension arm bolt can cause a catastrophic crash. Fix: Check all visible hardware before and after every single run. Use blue Loctite on critical fasteners.
• Mistake 5: Choosing the Losi 5ive as a first RC vehicle. The 5ive requires real mechanical knowledge and patience. Gas tuning and break-in procedures are not beginner-friendly. Fix: Start with an electric truck like the X-Maxx or even the Traxxas Maxx 4S before stepping into gas territory.
• Mistake 6: Driving in environments too tight for the vehicle. Both trucks are enormous. Driving them in small backyards, near cars, or around people and pets creates real risk of damage and injury. Fix: Always use open spaces, ideally purpose-built bashing areas or large empty car parks.
• Mistake 7: Ignoring the upgrade ecosystem when buying. Some buyers purchase these trucks then discover the parts or upgrades they want are expensive or unavailable. Fix: Research the upgrade path before buying. The X-Maxx’s Traxxas ecosystem is among the richest in RC. Check resources like our top RC car brands guide for brand context.

Which is faster — the Losi 5ive or the Traxxas X-Maxx?

The Traxxas X-Maxx on 8S LiPo is faster, capable of exceeding 50 mph. The Losi 5ive-T 2.0 tops out around 35 mph with its 32cc gas engine. However, the 5ive has massive torque and a driving character that the electric X-Maxx doesn’t replicate. Check the X-Maxx 8S on Amazon if top speed is your priority.

Is the Losi 5ive suitable for beginners?

No, the Losi 5ive-T 2.0 is not recommended for beginners. It requires engine tuning knowledge, a proper break-in procedure, and ongoing mechanical maintenance. Start with an electric truck like the Traxxas X-Maxx 4S and work your way up. The Traxxas also benefits from intuitive TSM stability control.

How long does a run last on the Traxxas X-Maxx?

On a typical 8S LiPo pack (two 4S batteries), expect approximately 20–30 minutes of run time depending on driving intensity. Hard bashing will deplete packs faster than moderate cruising. Having two or three pairs of 4S batteries ensures you can keep driving while others charge.

What fuel does the Losi 5ive use?

The Losi 5ive-T 2.0 runs on standard 91+ octane pump gasoline — the same fuel you’d put in a small car. No special RC fuel is needed (unlike nitro RC cars). This makes it very cost-effective to run and easy to source fuel anywhere. Mix with a small amount of 2-stroke oil at the manufacturer’s specified ratio.

Can the Traxxas X-Maxx handle water and mud?

Yes — the X-Maxx is fully waterproof. You can drive through puddles, mud, and rain without worrying about electrical damage. It’s one of the truck’s most celebrated features. Always rinse and dry after wet runs and check for debris in the drivetrain.
