Important Notice – Certification
⚠️The MIG 40 engine does not have aeronautical certification.
Its use in aircraft is restricted toexperimental, recreational or research applications, and it is the responsibility of the integrator, builder, or operator to comply with applicable local standards and regulations.
Important Notes
- Power, current, and thrust depend on the cooling system, controller, propeller, and mission profile.
- Peak power operation should be time-limited according to the application; please confirm this in the product datasheet available for download.
- The flange kit is not included with the motor and must be purchased separately.
