Choosing parts for fpv motors & escs often comes down to a practical question: do you need one clearly specified motor, or a multi-motor set with its quantity and intended drone sizes spelled out? The CM 3115 TAURUS FPV Drone Motor and the 4x SURPASSHOBBY BAT S15 S22 Series Brushless Motor address those different buying briefs. The listed-price gap is USD 8.95. Neither title presents a 4 in 1 FPV ESC or a motor-and-ESC combo, so this is a motor-versus-motor decision.
Quick verdict
CM 3115 TAURUS is the more direct choice for a single motor and its stated 900KV option. SURPASSHOBBY is the better match when a four-piece pack is the priority, with a named S2208-1950KV model and applications covering 3-inch, 3.5-inch, 4-inch, and 5-inch FPV drones. The deciding factor is format and build scope, not simply which KV number is larger.

Where each product wins
- CM 3115 TAURUS FPV Drone Motor: Its description gives concrete physical matching points, including a motor size of D 37.1 × 52.8 mm, a 5 mm propeller-mounting hole, a 5 mm shaft diameter, and M3×4 motor-mounting holes. That makes it a useful choice when those exact dimensions need to align with the rest of a build.
- 4x SURPASSHOBBY BAT S15 S22 Series Brushless Motor: The title names the S15/S22 series and explicitly covers 3-inch, 3.5-inch, 4-inch, and 5-inch FPV drone applications. It is the more direct route for a build that falls within one of those named size descriptions.
Product notes
CM 3115 TAURUS FPV Drone Motor
The CM 3115 TAURUS FPV Drone Motor is the straightforward choice when the brief calls for one clearly named motor. The title centers the TAURUS CM3115 V1.0, while the selected version is 900KV, giving shoppers a specific designation to match against a build. The listed price is USD 54.90. Its practical limitation is purchase scope: the title names a single motor rather than a four-piece set, so it is less direct for a full multi-motor replacement. The detailed mounting and cable specifications are useful matching points, but they do not establish that this motor is superior to a different KV value. Choose CM when the TAURUS name, one-unit format, and 900KV selection fit the job.
4x SURPASSHOBBY BAT S15 S22 Brushless Motor
The 4x SURPASSHOBBY BAT S15 S22 Series Brushless Motor targets a different buying brief: a defined four-piece motor set. Its model is 4PCS S2208-1950KV, and it carries Universal compatibility and Electric fuel-type designations. Those details make the pack identity clear without implying that 1950KV is automatically better than 900KV. The limitation is price: the listed amount is USD 8.95 above the CM 3115 TAURUS. The stated drone-size scope is also specific, so the title speaks most directly to the named 3-inch through 5-inch applications. Pick SURPASSHOBBY when that pack format and application range match your build.
Final choice by use case
Choose CM 3115 TAURUS FPV Drone Motor for a TAURUS-focused, single-motor purchase where the 900KV option and detailed mounting specifications are useful matching points. Choose 4x SURPASSHOBBY BAT S15 S22 Series Brushless Motor when the project calls for a multi-motor set and its named S15/S22 application range. If the actual requirement is a 4 in 1 FPV ESC, neither of these motor listings is the relevant type.
