The OddityRC Spinnybois 1405 motor is offered as 3200KV 6S and 4800KV 4S variants. These are the motor choices identified in the XI25 Pro O4 Pro configuration. For an existing XI25 or a compatible custom build, choose the complete power configuration first and keep the motor KV tied to it.

KV is a configuration choice
The XI25 listing pairs 3200KV with its 6S configuration and 4800KV with its 4S configuration. Treat these as matched purchase options. A higher KV number does not establish a better result for an aircraft that was configured for a different supply and motor combination.
When replacing a motor, record the selected aircraft version and inspect the markings on the installed motor. If the two disagree or the aircraft has been modified, resolve the full setup before ordering. A title containing “4S/6S” describes options; it is not a substitute for identifying the current build.
Match the propulsion system as a set
The XI25 product identifies 2.5-inch propeller options including DT63-3V2, DT63-4 and DT63-5. Choose the actual propeller, motor and battery combination with the aircraft configuration in mind. Different blade counts change the setup being evaluated; do not infer a measured efficiency or thrust advantage from blade count alone.
Check the mechanical installation too: motor mount, shaft and propeller attachment, screw length, wire routing and clearance. The motor listing does not supply a full mechanical drawing or thrust chart in its current text, so request the exact dimensions or load data if your custom build depends on them.
Use a replacement to restore a known baseline
Inspect the other propulsion components after an impact rather than changing only the visibly damaged motor. Record which propeller and motor were fitted, keep the established configuration available, and make one change at a time when evaluating the repair.
For a filming setup, measure the complete aircraft with the actual battery and accessories. The XI25 O4 Pro’s approximate ready-to-fly reference is 320g, with configuration dependence. The motor’s KV selection alone does not establish takeoff weight, flight time, payload capability or the result of a filming route.
Before you choose
- Identify 4S 4800KV or 6S 3200KV before purchase.
- Check mechanical fit and the intended propeller configuration.
- Restore and document the complete aircraft baseline after a repair.
Frequently asked questions
Which 1405 option is listed for the XI25 6S setup?
The XI25 specification pairs its 6S configuration with Spinnybois 1405 3200KV motors.
Can I choose the 4800KV option just because the number is higher?
Choose the variant specified for the complete power configuration. The current 4800KV selection is labelled 4S.
Does the motor listing establish a flight-time improvement?
No. A motor variant is not a measured endurance comparison. Battery, propeller, weight, route and conditions all affect the result.
