FPV Motors & ESCs: How to Choose by KV, Mount Details, or a 4-Motor Pack

Choosing among FPV motors means balancing KV selection, shaft and mounting details, package format, and price. Here's how four BSC and Eachine choices line up for a target KV, a 2-3S T-mount setup, or a specific motor format.

Last updated Aug 24, 2026

Quick take

Choosing FPV motors & ESCs can get complicated when a build depends on one KV selection, a particular shaft or hole pattern, or a complete motor package. The four choices here vary in motor model, listed KV, dimensions, mounting details, condition, and price. Match the fixed requirement first; use price as the tie-breaker only after the hardware details line up.

  • KV-led purchase: Compare BSC 2807.5, BSC 2207.5 V2, and BSC 2812 by their selected KV values.
  • Bundled format: Eachine 1104 is the entry to consider when a four-motor package is the deciding requirement.
  • Mounting-led purchase: Read the shaft, hole-pattern, prop-mount, and cable details before choosing by model name alone.

Product notes

BSC 2807.5 FPV Drone Motor

BSC 2807.5 FPV Drone Motor

BSC 2807.5 is a strong match when the build calls for the listed 1750KV selection. Its description specifies a 5 mm shaft, D19 M3×4 mounting holes, a 250 mm cable, 12N14P, and a 33.6×36.4 mm motor size. Those details give a clear reference point for a frame and wiring layout already built around them. The limitation is the selected KV: 1750KV is not the direct match for a build targeting the 1950KV selection on BSC 2207.5 V2 or the 1155KV selection on BSC 2812. Choose it for its named KV and physical specifications, not simply its model number.

BSC 2207.5 V2 FPV Drone Motor (1750KV / 1950KV / 2100KV

BSC 2207.5 V2 FPV Drone Motor (1750KV / 1950KV / 2100KV

BSC 2207.5 V2 makes sense when 1950KV is the required selection. Its title also presents 1750KV and 2100KV choices, while the selected attribute is 1950KV. The description lists a 4 mm shaft, D16 M3×4 mounting holes, and a 150 mm cable, giving this motor a different dimensional profile from the other BSC entries. Those same details are the limitation for a build designed around a 5 mm shaft or a 250 mm cable. The listed 1950KV selection is the concrete reason to choose it; the shaft, mounting-hole, and cable specifications should settle whether it belongs in the build.

BSC 2812 FPV Drone Motor

BSC 2812 FPV Drone Motor

BSC 2812 belongs on the shortlist for a build calling for the listed 1155KV selection. It specifies a 5 mm shaft, D19 M3×4 mounting holes, a 250 mm cable, and a 33.6×41.7 mm motor size. The shaft, hole pattern, and cable length match the corresponding details shown for BSC 2807.5, while the motor model and selected KV differ. Its limitation is that 1155KV is the selected value, so it does not answer a requirement specifically set at 1750KV or 1950KV. Choose BSC 2812 when that stated KV is the target and the listed 5 mm, D19, and cable details fit the build plan.

Eachine 1104 - 6000KV KV FPV drone motors x4 T mount props 9x9mm mount 2-3S

Eachine 1104 is the package-format choice when 2-3S power and T-mount propellers are part of the brief. The description also names 9×9 mounting, a 4 mm shaft for M2 screws, and about 50 mm of motor wire, creating a very specific hardware profile. The limitation is condition: this entry is marked Used, while the three BSC entries are marked New. Its USD 55.00 price is also the highest in the comparison, so the stated mounting details and bundled format should be the reason to choose it rather than an assumption about performance. The 6000KV title value is another reason to keep it separate from the BSC choices.

Final recommendation by use case

  • For a specific KV requirement: use the matrix to match the target value to BSC 2807.5, BSC 2207.5 V2, or BSC 2812.
  • For a bundled motor purchase: choose the Eachine 1104 entry, provided its 2-3S and T-mount description matches the build brief.
  • For mounting details: compare BSC 2807.5 and BSC 2812 for the shared listed 5 mm shaft and D19 M3×4 pattern; BSC 2207.5 V2 lists the 4 mm shaft and D16 M3×4 pattern.

The practical order is simple: select the required KV, match the shaft and mounting details, then decide whether a bundled format or a single motor entry makes sense. The price table is most useful at the end of that process, when the remaining choices are genuinely comparable.
