Comprehensive Comparison: V3 vs V2
Chassis and Build Quality: The V3 features reinforced chassis components, tighter tolerances, and better overall build quality. The V2 is solid but shows its age in comparison. If durability under stress is your priority, the V3 edges ahead.
Suspension and Handling: The V3’s redesigned A-arms and improved camber geometry make a tangible difference in high-speed corners. The V2 handles well but can feel squirrelish above 60 mph. For precision driving, V3 is superior. For casual bashing, V2 is perfectly adequate.
Motor and Power: Both use the same 3650 brushless motor options in 6S form. The difference in speed (2–3 mph) comes from better aerodynamics and transmission efficiency in the V3, not raw motor power. In 8S, the V3’s reinforced structure handles power better.
Parts Availability: The V2 wins decisively here. Parts remain abundant and affordable. The V3 is newer, so parts aren’t as deeply stocked yet, but availability is improving. For long-term ownership of a V2, you’ll have an easier time sourcing replacements.
Long-Term Value: The V3 should hold value better as it’s the current generation. The V2, while proving itself reliable, will depreciate faster as production winds down. If you plan to sell in 2-3 years, V3 is the safer bet.
Price-to-Performance: The V2 6S RTR offers the best bang for the buck. The speed difference doesn’t justify the $100+ premium of V3 for casual bashers. For competitive drivers or those wanting cutting-edge platform, V3 is worth it.
Essential Setup and Configuration Guide
Getting Your Infraction Ready: V2 or V3
Whether you’ve chosen the V2 or V3, proper setup is crucial for optimal performance and longevity. Follow these steps to configure your Infraction correctly.
What You’ll Need:
- LiPo battery charger with balancer (included charger works, but balance charger is better)
- Spare body and window lexan (you will crash and damage the body)
- Spare tie rods and turnbuckles (frequent wear items)
- Spare driveshaft (break points under stress)
- Servo saver (optional but recommended) – protects expensive servo
- Shock oil (25–40 weight silicone) for suspension tuning
- Ceramic bearing upgrade kit (improves speed, reduces friction)
- LiPo battery storage case (safety essential)
Step 1: Battery Preparation and Charging
- Remove the included 2000mAh or 2200mAh LiPo from packaging
- Inspect the battery for physical damage (swelling, dents, punctures)
- Install the battery into the waterproof battery box on the chassis (V3 and V2 have identical placement)
- Connect the battery to the Hobbywing Fusionpro ESC using the XT60 connector
- Charge the battery using the included charger in “LiPo” mode, or better yet, a balance charger set to 2S (6S batteries are 6 cells = 2 parallel 3S packs)
- Fully charge before first run (takes approximately 45–60 minutes)
- Store charged batteries in a dedicated LiPo storage case to prevent accidental discharge and fire risk
Step 2: Receiver Pairing and Transmitter Binding
- Power on the included 2.4Ghz transmitter (4–5 seconds hold)
- With the transmitter on, power on the ESC by connecting the battery
- Listen for binding beeps from the receiver (located in the chassis near the servo)
- The receiver should automatically pair with the transmitter during startup
- Test all transmitter functions: throttle (should vary 0–100%), steering (left/right full deflection)
- Do a range test by walking 10 feet away while transmitter is powered—car should be fully responsive
Step 3: Basic Geometry Checks
- Wheelbase measurement: V2 is 320mm, V3 is 325mm. Measure center of front wheel axle to center of rear wheel axle. If significantly different, you may have bent suspension components from shipping
- Camber angle: Looking at the front wheels from the front, they should angle slightly inward at the top (2–4 degrees negative camber). Adjust via the camber links if off
- Ride height: With a weight in the driver’s seat position (use a small water bottle for weight), the chassis should be about 0.75–1 inch above the ground. Too high = weight transfer issues; too low = bottoming out
- Suspension sag: Compress the suspension by hand and release. It should return smoothly without bouncing excessively. If bouncy, your shock oil is too light; if sluggish, it’s too heavy
Step 4: Differential Setup
- Locate the center differential (middle gear on the chassis)
- Check that front and rear diffs turn smoothly when manually rotating wheels
- Most stock Infractions come with “1/3 spool” (limited-slip) diffs—adequate for bashing
- If planning serious upgrading, consider full spool differential upgrade for better traction on loose surfaces
- Never completely lock the diffs unless specifically for rock crawling—this reduces turning radius
Step 5: Suspension Tuning for Your Driving Style
- Shock Selection: Stock shocks come with moderate 25wt oil. For faster driving, try 30–35wt. For softer riding, try 20wt
- Spring Rate: Stock springs are adequate for most bashing. If the car feels too stiff, try softer springs (lighter kg rating)
- Anti-Roll Bars (Sway Bars): Stock bars are fine. Stiffer bars reduce body roll in corners but make suspension less compliant on rough ground
- For detailed guidance, see our comprehensive RC Car Suspension Springs Tuning Guide
Step 6: Pinion Gear Setup
- The stock 3650 motor comes with a pinion gear installed (typically 23–25 teeth)
- Measure from the center of the motor shaft to the center of the spur gear with a ruler—should be approximately 3/8 inch spacing
- Adjust via motor mount screws if spacing is off
- For more speed, upgrade to a higher-tooth pinion (27–29T gives 2–5 mph more speed)
- For more torque, downsize the pinion (21–23T reduces speed but improves acceleration)
- See our Pinion Gear Calculator guide for precise calculations
Step 7: First Run Protocol
- Find a wide, open area free of obstacles (parking lot minimum 100 feet x 100 feet)
- Start with throttle trim at neutral and steering trim centered
- Accelerate slowly to test braking—confirm brakes respond immediately
- Drive in figure-8 patterns to test turning at increasing speeds
- Never run full throttle on the first run—test at 50% throttle first
- Feel for any pulling or unusual handling—indicates geometry issues
- Run for 8 minutes maximum (battery management), then let cool for 10 minutes
- Inspect the entire car for loose connections, leaks, or damage before second run
Step 8: ESC Programming (Advanced)
Both V2 and V3 use Hobbywing Fusionpro ESC with programmable functions:
- Connect the transmitter
- Power on the ESC while holding the programming button on the ESC (small button on the side)
- Transmitter will beep, indicating programming mode
- Adjust throttle stick to select parameters (acceleration, max speed, brake strength)
- For beginners, stock settings are excellent—don’t change unless specific need
- See our ESC Programming guide for detailed parameter explanations
Common Mistakes to Avoid
Learning from others’ mistakes saves time, money, and frustration. Here are the most common errors new Infraction owners make:
-
Mistake: Ignoring Battery Safety Protocols
The Problem: LiPo batteries can catch fire if overcharged, over-discharged, or physically damaged. New owners often leave chargers unattended or store batteries improperly.
The Fix: Always use a balance charger, never leave charging unattended, store batteries at 3.8V per cell (50% charge for long-term storage), and use a dedicated fireproof LiPo storage case. If a battery puffs or feels warm during charging, stop immediately.
-
Mistake: Not Checking Gear Mesh Before Running
The Problem: Improper gear mesh (spacing between motor pinion and spur gear) causes grinding noise and tooth stripping. Many owners run their car without checking this critical setting.
The Fix: Before first use, verify the pinion-to-spur gap is 3/8 inch (measure with a ruler from center to center). Adjust the motor mount forward/backward to achieve proper spacing. Detailed gear mesh adjustment guide here.
-
Mistake: Running Low on Fuel/Battery Time
The Problem: Pushing the battery or fuel beyond its limits causes brownouts, limp-mode performance, and potential motor damage. Beginners don’t realize when their battery is depleted.
The Fix: Set an 8-minute timer for each battery pack. Land the car before the timer ends—this prevents LiPo over-discharge (fatal to battery longevity) and gives plenty of brake response. Use low-voltage alarms as backup warnings (beeps when battery drops to dangerous levels).
-
Mistake: Ignoring Maintenance After Dusty or Wet Runs
The Problem: Dust and moisture destroy bearings, corrode electronics, and cause premature wear. Owners often just run the car without cleaning afterward.
The Fix: After every run, especially in dust or water, compressed-air blast the chassis and bearings to remove debris. Wipe down electronics with a dry cloth. Apply ball joint grease to suspension pivot points every 2-3 runs. See our complete maintenance kit guide.
-
Mistake: Using Undersized or Damaged Spare Parts
The Problem: When your car breaks (and it will), using cheap or incorrect replacement parts compounds problems. Many beginners buy the cheapest tie rods or driveshafts available, which fail immediately.
The Fix: Stock genuine Arrma replacement parts, not cheap knockoffs. Buy genuine Arrma spare parts kits as preventive investment. Quality upgrades like aluminum turnbuckles cost slightly more but last 10x longer than plastic versions.
-
Mistake: Neglecting Receiver/Transmitter Range Tests
The Problem: Signal loss during driving causes loss of steering or throttle control, resulting in crashes. Owners assume the radio link is fine without testing range.
The Fix: Before every session, walk 20 feet away with the transmitter while car is stationary. Test all control inputs—if any response is delayed or sluggish, reprogram the receiver binding. If still problematic, try new transmitter batteries or relocate farther from WiFi interference.
-
Mistake: Over-Tightening Fasteners
The Problem: Owners unfamiliar with model car assembly over-tighten screws, stripping threads and cracking plastic parts. This is extremely common with shock mounts and suspension components.
The Fix: Tighten fasteners until snug (when you first feel resistance), then add just 1/4 turn more. Never use power drills on RC parts. If you need to remove a stripped screw, use a rubber band between the screwdriver and screw for better grip, or drill a small hole and use a screw extractor.

Frequently Asked Questions
Is the Arrma Infraction V3 truly worth the $100+ price premium over the V2?
Yes, but only if you value improved handling and plan to keep the car long-term. The V3’s redesigned suspension geometry delivers noticeably better high-speed stability (especially noticeable above 55 mph), and reinforced components mean fewer repairs. However, if you’re a casual basher who won’t push speed limits or plan to sell in 6 months, the V2’s $100 savings might be better spent on extra batteries and charging equipment.
Can I upgrade a V2 to V3 specs with aftermarket parts?
Partially, yes. You can retrofit V3-spec A-arms, suspension geometry, and some chassis components onto a V2 frame. However, this piecemeal approach costs $150–$250 total and doesn’t address every improvement. For serious upgrades, it’s usually more cost-effective to simply purchase the V3 RTR outright. Check Arrma compatibility information on Amazon before buying upgrade parts.
Which version is better for beginners: V2 or V3?
The V2 6S RTR is better for true beginners because of its $100 lower price point. Beginners will crash frequently (expect 5–10 crashes in the first 10 hours), so the lower investment reduces the financial sting. The V2’s massive parts availability also means repairs are cheaper. Once you’ve mastered basics and want to upgrade, move to V3.
Is the V3 8S RTR appropriate for experienced 6S drivers?
Yes, if you’re genuinely experienced with high-speed RC cars and have appropriate driving space (nothing smaller than a large soccer field). The V3 8S requires different throttle control and braking technique than 6S—experiment gradually. Watch our ESC programming guide to adjust acceleration curves for 8S smoothness.
What’s the typical lifespan of an Infraction V2 or V3 before major repairs?
With proper maintenance, both platforms typically need major repairs after 20–30 hours of moderate bashinging (longer if gentle driving, shorter if extreme bashing). The V3 delays repairs slightly due to better engineering, but both eventually need driveshaft, bearing, or suspension component replacement. Budget $200–$400 annually for typical maintenance and repairs.
Can I run the Infraction V2 or V3 in water or snow?
Light splashing is fine (both have sealed electronics), but full water submersion is not recommended—even though Arrma makes some waterproof models. See our waterproof RC car guide for models specifically designed for water. Snow is fine—just rinse with fresh water afterward to prevent salt corrosion.
Which model has better tire and wheel options available?
Both V2 and V3 use the same tire fitment (12mm hex), so tire selection is identical. However, because V2 has been around longer, there’s a slightly larger selection of used tire options in the second-hand market. For new tires, check current tire availability on Amazon—stock varies regularly.
Is the Hobbywing Fusionpro ESC the same in both V2 and V3 versions?
The standard Fusionpro is the same, but the V3 8S RTR uses a Fusionpro rated for higher amperage to handle 8S power. Both are programmable with identical functions (acceleration, max speed, brake strength). The differences are minimal for 6S use—both deliver smooth, predictable performance.
What’s the price difference when fully equipped with spares and charging equipment?
A ready-to-bash V2 setup (car + 2 extra batteries + charger + spare parts) costs approximately $600–$750 total. A V3 setup runs $750–$900. If you opt for 8S V3, expect $900–$1,200 total including the required additional 8S LiPo batteries. For best value, start with V2 6S RTR + additional 6S LiPo packs and charger.
Which Infraction version will be easier to sell used in 2-3 years?
The V3 will be easier to sell as it’s the current generation with an estimated 5-7 year production run. The V2, while beloved and proven, is aging out—production has slowed, and used market values are declining. If you plan to upgrade within 3 years, V3 retains better resale value. List on RC car marketplace sites or Facebook groups for fastest sales.
