Choosing an FPV brushless motor means matching its KV and battery-cell setup to the build, not simply chasing a larger number. The other key decision is package scope: a single component can make sense for a targeted build, while a complete frame needs a different buying plan. The T-Hobby P1604 is positioned for a 3.5-inch freestyle drone and names a 3800KV/4S configuration, making the intended use fairly specific.
Quick verdict
At USD 21.16, the T-Hobby P1604 is a focused choice for a builder already using 4S and looking for the 3800KV configuration. The description provides concrete build specifications rather than vague performance promises, which helps when matching a motor to an existing design. The trade-off is that the purchase needs to match a particular build rather than serve as a general-purpose grab.
T-Hobby P1604
Choose the P1604 when the build calls for a brushless motor with a 24AWG x 120mm cable and 2mm shaft. Those details give the buyer concrete hardware parameters to account for alongside the 3800KV/4S pairing. The limitation is package scope: the packing list specifies one P1604 brushless motor, so it is not a multi-motor set.
Who it suits
This motor is most suitable for a 3.5-inch freestyle builder who has already settled the power-system requirements and wants hardware identified for that use. It also suits shoppers who prefer a defined motor weight and configuration rather than an unspecified component. The 11.6g weight supplies a clear planning number for the build, while the freestyle designation keeps the purchase tied to a particular kind of drone project.
What stands out
The P1604 has several concrete selection points beyond its main configuration. Its 12N14P configuration, 20.8 x 15.5mm size, and 11.6g weight give a builder measurable parameters to work into a design. These numbers do not, on their own, promise a particular flight feel or establish that one setup is superior; they simply describe the motor that is being considered. That straightforward specification is useful for a build where physical details matter.
Meaningful trade-offs
The main trade-off is specificity. The 3800KV/4S pairing is clear, but that clarity makes the P1604 a poor starting point for a build whose battery plan is still undecided. The package list also names one motor, so a full frame project requires planning beyond the package. Buyers should approach the P1604 as a defined component for a matching freestyle setup, not as a complete motor solution for an entire aircraft.
Bottom line
The T-Hobby P1604 is a clear match for the intended freestyle use when its physical specifications fit the build. Its focused purpose is useful for a defined project, while the single-motor package and 3800KV/4S pairing make configuration and quantity the two decisions to settle before buying.
