# FPV drone motor sizes: 1104 to 3115, shaft, prop thread and mount patterns

> What is the mounting pattern of a 2207 motor?

- Category: Electronics › RC & drones
- Kind: Modern device
- Basis: Maker spec pages (iFlight, EMAX, BrotherHobby, Hobbywing, GEPRC); T-Motor values via retailers copying its spec (marked)
- Page: https://xemstudio.com/objects/fpv-drone-motors/ · JSON: https://xemstudio.com/api/geometry?object=fpv-drone-motors · Plain text: https://xemstudio.com/objects/fpv-drone-motors/sheet.txt

- Use in every chat: add https://xemstudio.com/mcp as a connector (https://xemstudio.com/use-with-ai/)

**Exact dimensions.** True size, with no printing tolerance added.

## Notes

- Size code = stator diameter + height in mm (2207 = 22 mm × 7 mm stator); the can is bigger (a 2207 is about Ø29 × 32.6).
- Base mount patterns: 1104 / 1404 9 × 9 M2; 1806 (and iFlight's 2205) 12 × 12 M2; 2207 / 2306 / 2306.5 16 × 16 M3; 2806.5 / 2807 / 3110 / 3115 19 × 19 M3. Use screws no longer than the frame thickness + 3 mm or they hit the windings.
- Shafts: micro 1.5 mm; 22xx–31xx 5 mm with an M5 prop thread and flange nut (iFlight) — makers differ: EMAX RS2205 3 mm shaft with M5 thread, T-Motor F60 4 mm with a 5 mm prop mount.
- Mount-pattern hole diameters are given as φ2 (M2) and φ3 (M3); the motor-envelope files carry tapped-size holes 3 mm deep.
