Choosing among fpv motors & escs can be tricky when the actual decision is between two standalone motors with different specifications. The BSC 2807.5 and BSC 2812 are close enough in price to invite a quick comparison, but their listed KV options and motor dimensions point to different build priorities. The useful question is not which number looks more impressive; it is which motor matches your planned setup.
Quick verdict
The BSC 2807.5 is the price-led route, while the BSC 2812 is the layout-led alternative. Use the comparison below to separate cost and shared hardware details, then let the motor's listed KV option decide which specification fits your build plan. Neither motor should be treated as universally better from numeric values alone.
At-a-glance comparison
| Product | Listed price | Condition | KV option |
|---|---|---|---|
| BSC 2807.5 FPV Drone Motor | USD 24.00 | New | 1750KV |
| BSC 2812 FPV Drone Motor | USD 29.99 | New | 1155KV |
Where each wins
- BSC 2807.5: This is the stronger choice for a cost-first decision. At USD 24.00, it is $5.99 below the BSC 2812, making the price difference easy to quantify without treating it as a performance claim.
- BSC 2812: This suits a layout-led decision centered on its listed D 33.6 × 41.7 mm motor size. That dimension is a concrete planning reference, not evidence that the motor is inherently better.
Both motors list a New condition, a 250 mm black silicone cable, an M5 nut, M3×4 mounting holes, and a 5 mm shaft. Those shared details describe the hardware but do not create an advantage for either motor. The meaningful separation is the listed price, motor size, and KV option.
Product notes
BSC 2807.5 FPV Drone Motor

With its listed D 33.6 × 36.4 mm motor size, the BSC 2807.5 is a sensible choice when that dimension is the one your layout is built around. The description also identifies a 250 mm black silicone cable, an M5 nut, M3×4 mounting holes, and a 5 mm shaft, giving you concrete hardware references for planning. Its limitation is scope: the title identifies a motor rather than an FPV motor-and-ESC combo, so it does not cover the 4-in-1 ESC side of a broader setup. The dimensions and hardware details describe the part, but they do not establish compatibility with a particular frame or propeller.
BSC 2812 FPV Drone Motor

With a listed D 33.6 × 41.7 mm motor size, the BSC 2812 fits a different planning brief. Choose it when that particular dimension is the reference your layout requires. Its description also specifies a 250 mm black silicone cable, an M5 nut, M3×4 mounting holes, and a 5 mm shaft, so the mechanical details are clearly defined for comparison with existing hardware. The limitation is scope: BSC 2812 is identified as a motor, not a motor-and-ESC combo, so it does not address the 4-in-1 ESC portion of an FPV motors & escs setup. Those measurements still do not establish compatibility or performance by themselves.
Final choice by use case
- Price-first use case: Choose BSC 2807.5 FPV Drone Motor.
- Layout-first use case: Choose BSC 2812 FPV Drone Motor when its listed motor dimensions are the intended reference.
- Specification-first use case: Use the KV option that matches the build plan: 1750KV for BSC 2807.5 or 1155KV for BSC 2812. That is a matching decision, not a claim that one value is universally superior.
For shoppers seeking a motor and a 4-in-1 ESC together, neither title describes a combo, so this head-to-head is specifically a motor choice.
