A larger motor still has to be matched properly
The BOOMFPV(炸机大叔) 3115 brushless motor is 900KV, featuring a black bell with silver spokes and a threaded prop shaft. Rotor, base, and lead details are shown one by one above.
A reference fit for 9–10 inch frames
This motor can be used as a reference on 9–10 inch builds, with 6S as the reference power setup. The current load table was tested with an HQ9×5 3R propeller at 25.2V. If you fit a 10 inch propeller, re-check the load against that specific propeller, all-up weight, ESC, and battery. Do not reuse the 9 inch propeller figures as-is.
Read the power data with the test conditions
In the supplied load table, an HQ9×5 3R propeller at 25.2V and 100% throttle produced 4566g of thrust on a single motor, at 64.6A, 1627.9W, and 15932RPM. The table above keeps the figures at other throttle points for comparison. These are single-motor results under the stated test conditions. They are not the all-up thrust of an aircraft, and they are not the result for every build.
Check the interfaces and the space before you build
The photos above show the threaded prop shaft, the four-hole base, and the three-phase leads. When you choose parts, check frame space, the actual mounting holes, how the propeller is secured, and screw length. ESC and power connections should also be confirmed against the chosen propeller and load. Finish the build, then tune in steps.
