Overview
The VCI SPARK 1103 is a compact brushless motor set (2pcs) for micro RC builds, offered in 7500KV and 11000KV options. Both versions use an 1103 stator (Ø11×L3 mm) and share the same mechanical dimensions for consistent fitment across lightweight FPV and mini multirotor platforms.
Key Features
- Available KV options: 7500KV or 11000KV
- Compact 1103 format with 9S12P configuration
- N52SH arc magnets
- 28AWG silicone wire, 50 mm length
- 4x M2 mounting holes
