4. Guide to avoiding pitfalls when purchasing motors
1.Avoid KV value mismatch: High KV motors using 4S batteries will cause overheating
2.Pay attention to the installation hole distance: Three-inch racks usually support two hole positions: 12/16mm.
3.Pay attention to bearing quality: Ceramic bearings are more resistant to high-speed operation than steel bearings
4.Power matching ESC: It is recommended to choose BLHeli_32 ESC above 25A
5. New technology trends in 2024
According to the latest discussion on the RCGroups forum, three-inch mobile phones are showing three major trends:
•Ultra lightweight: New 1302 motor (9g/unit) becomes popular
•6S high pressure system: Requires special low KV (around 2800KV) motor support
•Magnetic steel upgrade: N52SH magnet provides higher magnetic flux
From the above structured data analysis, it can be seen that the motor selection of the three-inch flying machine needs to comprehensively consider the flight scenario, battery voltage and propeller matching. It is recommended that novices start with the mainstream 1404 motor, and advanced players can try the latest ultra-lightweight solution.
