SureFly Magneto

4-Cylinder Impulse Coupled Mag Replacement

Replaces 4-cylinder non-impulse coupled magnetos on Lycoming and Continental engines.

Weight: 4.0 lbs

About SureFly:

SureFly is an FAA certified electronic (solid state) magneto replacement. The SureFly Ignition Module (SIM) replaces one magneto, generally the left or impulse-coupled/starting magneto on most aircraft engines. 4- and 6-cylinder SIMs are available for Lycoming and Continental engines.

Replacing just one traditional magneto eliminates magneto maintenance and cuts associated costs in half! Zero maintenance, zero rebuilds, and zero overhauls. Run it to 2,400 hours of SIM operation.

• Delivers more consistent spark energy with higher accuracy!
• 2,400-hour operating time, no 500-hour inspections
• No mechanical parts that wear
• Low power consumption
• Up to 2lbs lighter than a Bendix magneto
• Very easy to install!

FAA-STC approved for many Cessna, Piper, Beechcraft, Maule, Mooney, and more aircraft.

Intelligent timing advance:

For non-turbocharged engines, SureFly controls spark advance up to 38º before TDC as determined by manifold pressure and RPM (engine power setting). Each engine's base timing advance is read off the data plate and set into the SureFly Ignition Module or, "SIM" at installation. The timing advance schedule is hard set at the factory, when the SIM is manufactured, to provide the highest possible combustion efficiency.

No mechanical points:

Not only are points and condensers a point of failure in magneto ignitions, so are rotors and caps as they carbon track and provide alternate paths to ground as resistance builds in the system. That's why SureFly utilizes none of these antiquated technologies. SureFly components are all solid state and industrial-grade electronics.
