Technical Performance
This combo represents serious engineering for demanding 1/10 scale RC truck and monster truck applications. The MAX10 G2 ESC is rated for 140 amps of continuous current with an impressive 880-amp peak rating, giving you the raw power to accelerate hard without voltage sag or thermal throttling. The controller accepts 2-4S LiPo batteries (7.4v to 14.8v nominal), offering flexibility across a wide range of battery configurations. The BEC (battery eliminator circuit) provides clean 6 or 7.4-volt power output at 5 amps to run your servo and receiver, though the 7.4-volt output requires a minimum 3S battery input. The included EzRun 3665 SD G3 brushless motor is purpose-built for this pairing, boasting a 2400KV rating that delivers the perfect balance of acceleration and top speed across the supported battery range. The motor features a compact 37mm diameter with 65.8mm length, optimised to fit within standard 1/10 truck motor mounts whilst maintaining sufficient internal volume for high-efficiency rotor construction. The 4-pole design and 5mm shaft diameter ensure compatibility with standard 1/10 drivetrain components including pinion gears and differential spools. Motor resistance of 0.00816 ohms and no-load current of just 5.2 amps indicate an exceptionally efficient winding design that minimises parasitic losses and heat generation. The motor tips the scales at 304.5 grams, a substantial but necessary weight that provides thermal mass for heat dissipation and structural rigidity during aggressive acceleration. Both the ESC and motor benefit from professional-grade construction with sealed bearing surfaces, quality winding techniques and robust connector systems featuring XT60 battery connectors and 4.0mm gold-plated bullet connectors for motor leads. The 30x30x10mm frameless fan provides active cooling with BEC power, sized appropriately for the 140-amp ESC's thermal management needs. Programming is handled via the SET button on the ESC for quick adjustments, or by connecting the optional LCD Program Box or OTA Programmer module for advanced configuration. This system delivers genuine 1/10 competition-grade performance with the reliability expected from Hobbywing's professional pedigree.

Frequently Asked Questions
- Is the MAX10 G2 good for beginners or experienced bashers? — This is genuinely suitable for both skill levels, though beginners should have basic RC knowledge. The sensored motor provides smooth, predictable throttle response that's easier to control than sensorless systems, and the intelligent fan and capacitor management means you don't need to baby the system. Experienced racers will appreciate the 32-degree turbo timing adjustment and 25% speed increase potential when paired with 4S batteries. If you're entirely new to RC, we'd recommend learning basic setup and maintenance concepts first, but this combo is absolutely worth the investment as your skills develop.
- What battery does this combo need and how do I choose between 2S, 3S and 4S? — The system supports 2S (7.4v), 3S (11.1v) and 4S (14.8v) LiPo batteries. For casual bashing and maximum runtime, a 2S or 3S pack works perfectly well. For maximum speed and aggressive acceleration, a 4S pack unlocks the full potential of the 2400KV motor rating, delivering approximately 25% more top speed when you utilise the turbo timing adjustment. Budget roughly 1500-2000mAh capacity minimum for reasonable run times—larger packs provide longer bashing sessions but add weight. Always charge and store LiPo batteries correctly, and use a quality charger with balance connector monitoring.
- How does the waterproof IP67 rating compare to other brushless RC systems? — IP67 is the same military-standard waterproofing rating used in professional applications, guaranteeing protection against complete temporary immersion in water up to 1 metre depth for 30 minutes. Most consumer brushless RC systems offer lower ratings like IP65 or no rating at all, so the MAX10 G2 with its sealed ESC and waterproof sensored connector provides genuine all-weather capability. You can confidently run through water crossings and rain showers without worrying about short circuits or component failure. However, avoid prolonged submersion and always allow components to dry completely before storage.
- What's the real-world difference between this combo and the single 80A MAX10 G2 version? — The 140A version offers twice the continuous current capacity (140A vs 80A) and significantly higher peak power (880A vs 520A), supporting larger 4S battery packs and more aggressive motor combinations. The 140A is optimised for 1/10 trucks and monster trucks where you need high acceleration and sustained top-end power, whilst the 80A suits lighter vehicles and more conservative setups. If you're building a serious 1/10 truck or monster truck, the 140A is the correct choice and provides genuine value through increased capability without proportional cost increase.
- Can I use this combo with different motors or just the included 3665 SD G3? — The MAX10 G2 ESC supports any sensored brushless motor with compatible 4.0mm bullet connectors, and you can also run ordinary sensorless motors with separately-purchased standard sensored cable adapters. That said, the included 3665 SD G3 motor is specifically tuned and tested to work perfectly with the MAX10 G2, delivering the best throttle response and performance. If you want to experiment with different motors, the ESC will work, but overheating protection features are only fully activated when paired with the matching EzRun 3652/3665 G3 motor range.
- How does the smart fan technology actually save power and reduce noise? — The MAX10 G2 intelligently disables the frameless cooling fan during normal cruising and low-load conditions, eliminating the battery drain and noise that would normally come from running the fan continuously. The fan only activates when internal temperature rises above a threshold level where active cooling is genuinely needed. This means quieter, more efficient running during casual bashing whilst ensuring the fan kicks in automatically during sustained high-speed runs or extreme acceleration bursts. The result is audibly quieter operation and measurably longer runtime from the same battery pack.
- What does the 74% capacitor upgrade actually do for performance? — The significantly larger capacitor bank in the MAX10 G2 acts as an energy reservoir, storing and releasing power more effectively during acceleration spikes. This means smoother power delivery, reduced voltage sag when you demand maximum acceleration from a standstill, and better protection against battery sag-related glitches or ESC shutdowns. The double explosion-proof design with overheating protection prevents the capacitor from rupturing if voltage spikes or extreme current draws occur. Essentially, a bigger capacitor bank lets your system handle harder acceleration demands without as much risk of failure, and you'll notice snappier throttle response overall.
- Is data logging and telemetry important for casual RC bashing? — For pure fun bashing, telemetry is optional but genuinely useful. The optional OTA Bluetooth module and smartphone app let you monitor battery voltage, motor temperature and current draw in real-time, helping you avoid over-discharging your LiPo or running the motor into thermal throttling. For serious racers, data logging becomes more valuable—you can review historical graphs to understand thermal behaviour, identify power delivery inconsistencies and optimise tuning. For most RC enthusiasts, it's a nice-to-have feature rather than essential, but the fact it's available adds long-term value to your investment.
