Single-Twin CDI Tester

Single-Twin CDI Tester is an electronic diagnostic tool that generates a trigger signal to test spark generation on single and twin cylinder RC engine ignitions.

It replaces the engine’s Hall sensor during testing, allowing you to safely check if the CDI unit is functioning without needing to rotate the engine or flip the propeller.

• Tests both Single and Twin cylinder CDIs

• Compatible with CH and RCEXL ignitions

• Provides visual/audible confirmation of spark directly on the bench
