A power reference for 7 inch builds
The BOOMFPV（炸机大叔） 2807 brushless motor is 1300KV. This page shows the 1300KV version, featuring a black bell with silver spokes and a threaded prop shaft.
Check the specs first, then plan the build
The data lists a 6S working voltage and a reference fit for 7 inch FPV quads. The motor weighs 58.1g. Overall size is Φ34.7×22mm, with a 12N/14P configuration and 18AWG leads, 220mm long. The dimension drawing lists a 19×19mm base hole pitch, 4-M3 mounting threads, and an M5 prop-shaft thread. During installation, also check frame space, screw length, and where the leads exit.
Use the electrical figures together with the load
The parameter graphic lists 63mΩ phase-to-phase resistance, 1.6A no-load current at 16V, a maximum current of 48.28A, and a maximum power of 1124W. Maximum current and power are not the same as a continuous rating. When you choose an ESC, battery, and propeller, confirm them against the actual load and cooling.
Load reference for two 7 inch propellers
The photo set keeps 60%, 80%, and 100% throttle data for GF7040 and HQ7×4×3 propellers. At 100% throttle, a GF7040 at 23.36V produced 2186g of thrust on a single motor, at 41.33A and 965.4W. An HQ7×4×3 at 100% throttle and 23.29V produced 2302g, at 48.28A and 1124.4W. These results belong to the listed propellers and test conditions. They are not all-up aircraft thrust. Re-check after you change propellers or the all-up load.
Price and version
This page covers the 1300KV version. The "Baozao 700" marking in the photos is a series engraving and does not mean 700KV. Confirm quantity and the packing list when ordering.
