Hi,
Influenced by OS belt drive, contra systems and lately AR Single drive, I made my own for Sebart Miss Wind 50E:
At least as powerful as Hacker A50-16S but lighter. Runs very smooth and cooling is easy to arrange.
Shaft and prop fastening are spares from Hacker. Belt and larger tooth wheel are from ebay. Motor and smaller tooth wheel are helicopter components from 380 size (Goblin 380 etc.).
Design and cf plates are my own.
