When shopping for fpv motors & escs, the first question is not which number is highest-it is whether you need a standalone motor, a specific KV selection, or a DJI rear-right arm. The four entries split into three BSC FPV drone motors and one DJI replacement-arm listing. That makes the decision concrete: compare the motor model, selected KV, dimensions, shaft, and cable details, then keep the arm in a separate repair lane. These numbers are identifiers to match against your setup, not automatic performance rankings. If your search started with a 4-in-1 FPV ESC or FPV motor-and-ESC combo, read the product type carefully before treating a motor title as an ESC choice.
Quick take
- Choose BSC 2207.5 V2 FPV Drone Motor for the lowest listed price and the selected 1950KV specification.
- Choose BSC 2807.5 FPV Drone Motor when the 2807.5 model phrase and 1750KV selection are the key requirements.
- Choose BSC 2812 FPV Drone Motor when the 2812 model and 1155KV selection match the intended setup.
- Choose the DJI rear-right replacement motor arm for a repair that calls for the named DJI FPV arm, not a standalone FPV brushless motor.

Decision matrix
- Lowest listed price: BSC 2207.5 V2 FPV Drone Motor, with 1950KV selected.
- 2807.5 model and 1750KV: BSC 2807.5 FPV Drone Motor.
- 2812 model and 1155KV: BSC 2812 FPV Drone Motor.
- DJI FPV rear-right repair: New Genuine New Replacement Rear Right Motor Arm For DJI FPV Drone se.
- 4 in 1 FPV ESC or motor-and-ESC combo: separate that requirement from this group. The BSC titles identify FPV drone motors, while the DJI title identifies a rear-right motor arm, so the category label alone is not enough to make an ESC selection.
Product notes
BSC 2807.5 FPV Drone Motor
BSC 2807.5 FPV Drone Motor is the clearest choice when the 2807.5 model phrase and 1750KV selection are the anchors. The description lists a 33.6 × 36.4 mm motor size, 5 mm shaft diameter, M5 propeller-mounting nut, 250 mm cable, and 18# AWG black silicone cable. That gives a concrete set of details to compare with a build specification without treating any number as a performance verdict. Its limitation is the selected 1750KV specification, while the 2207.5 entry shows 1950KV. Pick this BSC motor when its model and cable details line up; do not choose it simply because 2807.5 is a larger-looking number.
BSC 2207.5 V2 FPV Drone Motor
BSC 2207.5 V2 FPV Drone Motor makes the most direct case for a shopper who wants the lowest listed price while selecting 1950KV. The title also presents 1750KV, 1950KV, and 2100KV as KV choices, while the selected attribute is 1950KV. Its description lists a 27 × 32.3 mm motor size, 4 mm shaft diameter, M5 nut, D16 M3×4 motor-mounting holes, 150 mm cable, and 20# AWG black silicone cable. Those details are the reason to shortlist it for a specification calling for the listed dimensions. The limitation is that its shaft, dimensions, and cable length differ from the BSC 2807.5 and BSC 2812 entries, so price alone does not establish interchangeability.
BSC 2812 FPV Drone Motor
BSC 2812 FPV Drone Motor suits a selection built around the 2812 model phrase and the listed 1155KV choice. The description gives a 33.6 × 41.7 mm motor size, 5 mm shaft diameter, M5 nut, D19 M3×4 mounting holes, 250 mm cable, and 18# AWG black silicone cable. The 250 mm cable and 5 mm shaft align with the corresponding details on BSC 2807.5, while the model and listed dimensions remain different. That distinction is useful when comparing replacement specifications. Its limitation is the $29.99 listed price and 1155KV selection; choose it for those concrete identifiers, not because a higher or lower KV number automatically means more performance.
DJI FPV Rear Right Replacement Motor Arm
New Genuine New Replacement Rear Right Motor Arm For DJI FPV Drone se belongs in a different decision lane. Its title identifies a rear-right motor arm for a DJI FPV drone, and the description specifies black color, an approximate 12.4 × 9 × 5 cm arm size, and a package containing one piece. Choose it when the repair calls for that named rear-right arm and DJI fit. The limitation is category-specific: it is not titled as a standalone BSC FPV motor, a brushless motor, or a 4 in 1 ESC, and its $32.99 listed price is the highest in this comparison. That makes the part focused for the named repair, not a substitute for a motor-and-ESC combo.
Final recommendation by use case
For the lowest listed price, choose BSC 2207.5 V2 FPV Drone Motor and its selected 1950KV specification. For a 2807.5 motor with 1750KV, choose BSC 2807.5 FPV Drone Motor. For the 2812 model with 1155KV, choose BSC 2812 FPV Drone Motor. For a DJI FPV rear-right repair, choose New Genuine New Replacement Rear Right Motor Arm For DJI FPV Drone se, since its title names that specific part. If the actual need is a 4 in 1 FPV ESC or a motor-and-ESC combo, keep that search separate and select a product title that explicitly identifies the required ESC or combo.
