1105 Brushless Motor for FPV Racing: Micro Whoop & Cinewhoop Power from X-TEAM

The 1105 brushless motor is the powerplant behind today’s most nimble FPV builds — from 75mm indoor whoops to lightweight 2-inch cinewhoops. At just Φ16×16mm and 8 grams, X-TEAM’s XTO-1105 delivers 30W on 2S with KV options from 1100KV to 4200KV, making it one of the most versatile micro motors available. Whether you’re threading gates in your living room or capturing smooth cinewhoop footage through a tight bando, the XTO-1105 punches well above its weight class — and with free custom KV winding, you get the exact RPM window your build demands.

XTO-1105: Specs That Matter for Micro FPV

The XTO-1105 is engineered for the weight-obsessed builder. Every gram counts when your entire quad weighs under 100g, and the 1105 form factor strikes the perfect balance between power density and mass. Here are the hard numbers:

For builds pushing past 100g AUW or running 2.5-inch props, X-TEAM also offers the XTO-1106 (7.5g, 120W peak, hollow-center cooling), giving you a step-up option within the same micro form factor.

KV Selection: 1100KV vs 3200KV vs 4200KV on 2S

With KV options spanning 1100KV to 4200KV, the XTO-1105 covers three distinct FPV use cases. Picking the right KV is the single biggest performance decision you’ll make:

KV data based on X-TEAM factory specifications. Actual RPM under load varies with prop pitch, battery sag, and ambient conditions.

Micro Whoop Racing: Why the 1105 Shines Indoors

The modern micro whoop scene has moved decisively toward brushless power. The 1105 4200KV on 2S is the sweet spot for 75mm and 85mm whoop frames — it spins 31,000+ RPM unloaded, responds to throttle changes in milliseconds, and weighs barely more than a 1S brushed setup while delivering 3-4× the power.

Compared to the common 0802 and 1002 motors found on 1S whoops, a 4200KV 1105 on 2S offers:

• 2× the continuous power — 30W sustained vs ~12-15W for 1S micro motors
• Lower sag under punch — 2S voltage holds better voltage under load than 1S, especially with modern 300-450mAh HV packs
• Broader prop compatibility — comfortably swings 40mm to 55mm props on whoop ducts
• No brush replacement — outrunner brushless design means zero maintenance on motor contacts

Pilots running BetaFPV Meteor85 or custom 85mm whoop frames on 1105 5000KV motors have set the competitive standard. The XTO-1105 4200KV slots right into that performance class — delivering the same relentless acceleration that indoor racing demands.

Cinewhoop Applications: Smooth Power for HD Footage

Cinewhoops live in a different world from race whoops. Where racing demands raw punch, cinewhoop flying prizes smoothness, stability, and predictable throttle response — the exact qualities that the 1100KV XTO-1105 variant was wound for.

On a 2-inch cinewhoop carrying a naked GoPro or Walksnail Avatar HD system (total AUW around 85-110g), the 1100KV XTO-1105 delivers:

• Silky throttle curve — no jumpy low-end, just smooth progression from hover to cruise
• 5-7 minute flight times — low KV on 2S with efficient bi-blade props stretches battery life
• Minimal vibration — precision dynamic balancing and curved arc magnets reduce jello in HD footage
• Quiet operation — lower RPM at cruise means less prop noise for indoor real estate and event filming

For builders who want even more headroom, the XTO-1106 bumps power to 120W with a hollow-center cooling structure — enough to carry a full DJI O4 Air Unit on a 2.5-inch cinewhoop frame. Both the 1105 and 1106 share the same micro mounting pattern, so upgrading is a bolt-on swap.

What Makes the XTO-1105 Different from Generic 1105 Motors

Curved Arc NdFeB Magnets

Most budget 1105 motors use flat magnets that leave inconsistent air gaps. The XTO-1105 uses curved arc neodymium magnets that follow the rotor circumference, creating a tighter, more uniform magnetic field. The result: smoother torque delivery at every RPM, less cogging at low throttle, and better efficiency across the entire power band.

Free Custom KV Winding — Any KV, No Extra Charge

Here’s what sets X-TEAM apart: need 2500KV for a specific prop-and-voltage combination? Or 3800KV to match your tune? We wind it. Our in-house winding team handles custom KV orders daily — no minimum quantity, no upcharge. This isn’t a batch-order compromise either; every custom-wound motor goes through the same dynamic balancing and QC as our standard KV variants.

Precision Dynamic Balancing

The 12-pole outrunner rotor is individually balanced to minimize vibration at 30,000+ RPM. For cinema pilots, this means cleaner gyro data and less work in post to clean up micro-jitters.

1105 vs 1106: Which Motor for Your Build?

The rule of thumb: if your AUW is under 100g and you want max agility, go 1105. If you’re carrying an HD system or pushing 2.5-inch props, the 1106’s 120W ceiling gives you the headroom to punch out without sag.

FAQ: 1105 Brushless Motor for FPV Racing

What battery should I use with an 1105 brushless motor?

The XTO-1105 is designed for 2S LiPo (7.4V nominal). For 4200KV indoor whoop builds, 300-450mAh 2S HV packs are ideal — they keep weight down while delivering enough current for 3-5 minute race heats. For 1100KV cinewhoop setups, 550-750mAh 2S packs extend flight time to 6-8 minutes on efficient bi-blade props.

Can I run an 1105 motor on 1S?

Technically yes — but the KV is wound for 2S voltage. On 1S, a 4200KV motor spins at just ~15,500 RPM unloaded, roughly half its design RPM. You’d lose significant thrust. For 1S whoop builds, consider a dedicated 1S motor in the 0802-1002 size class instead. If you need a custom 1S KV from X-TEAM, we can wind the XTO-1105 for 1S — just ask.

What props work best with the XTO-1105?

For 4200KV on 2S: Gemfan 40mm 4-blade or 45mm 3-blade on 75mm whoops; HQProp 51mm 3-blade or Gemfan 2020 4-blade on 85mm frames. For 1100KV on 2S: HQProp 65mm bi-blade or Gemfan 65R bi-blade for quiet, efficient cinewhoop cruising. Always check current draw when switching props — start with a lower-pitch option and measure.

How fast is a micro whoop with 1105 4200KV motors?

On a 75mm whoop at ~45g dry with 450mAh 2S, expect 50-65 km/h top speed with aggressive props. On an 85mm frame running 5000KV-class 1105s, competitive pilots routinely hit 70-80 km/h on a race course. XTO-1105 4200KV delivers comparable performance to BetaFPV 1105 5000KV motors — the slightly lower KV trades a few km/h of top speed for better efficiency and cooler running across a full pack.

Does X-TEAM offer 1105 motors with custom KV values?

Yes — free of charge. X-TEAM’s free custom KV winding service applies across the entire XTO series, including 1105 and 1106 motors. Whether you need 1100KV for cinewhoop, 3800KV for an unusual prop size, or any other KV between our standard ranges, our in-house winding team can deliver. Contact us at chris@x-teamrc.com with your target KV and build specs.

Build Recommendations: Putting It All Together

Here are three battle-tested configurations using the XTO-1105:

All configurations assume XT30 connectors. For 1100KV cinewhoop builds carrying HD cameras, make sure to test hover current before first flight — total amp draw across 4 motors should stay comfortably within your AIO ESC rating.
