stevron Posted October 6, 2020 Share Posted October 6, 2020 Has anyone fitted an airmaster electric inflight adjustable prop to a Lyncoming that has a light speed ignitions? The slip rings and ignition pick ups are in conflict Link to comment Share on other sites More sharing options...

IIRC, the LSE ignition uses magnets in the flywheel - same as the SDSEFI - as a timing reference. The pickup for those magnets sounds like it conflicts with the slip ring brush mounting for the Airmaster prop, and the prop slip rings in turn blocking the magnets from being detected by their sensor. Steveron you could try asking on Vans forum, but the Air Master prop is pretty slim pickings on the big Lycomings AIUI. Link to comment Share on other sites More sharing options...
skippydiesel Posted October 7, 2020 Share Posted October 7, 2020 Okay - Disclaimer - just a bush mechanic so some concepts need to be explained in simple terms. Is your concern related to radio interference/noise and/or ignition/propeller timing/rpm ? If radio noise you might want to talk to Kyle of Kyle Communications (this forum) for some sort of suppression/shielding system and/ or change in wiring rout. To the best of my, admittedly limited, knowledge the slip ring system on an electric prop are all about conducting power to an electric (step or linear ?) motor. In addition there is an rpm sensor that provides information (signal) to the CS controller - not sure how this signal is generated, could be a "hall effect" (magnetic) Simple electronic ignition systems use hall effect or photo/light crank sensors to trigger a coil(s)- this could be yours. Ignition & prop rpm sensors should not be upset by each another as long as they are not in close proximity Link to comment Share on other sites More sharing options...
walrus Posted October 7, 2020 Share Posted October 7, 2020 I don’t think Airmaster has any props for Lycoming or Continentals. They design for rotax engines and one or two others. Link to comment Share on other sites More sharing options...
skippydiesel Posted October 7, 2020 Share Posted October 7, 2020 Check out their web site - Lycoming 115 hp & Continental 100 hp - amongst several others Link to comment Share on other sites More sharing options...

He has now gone to Surefly and is extremely happy. Especially with the purchase price. And zero maintenance after fitment. https://www.aircraftspruce.com/catalog/eppages/surefly_08-17074.php Edited October 7, 2020 by Downunder Link to comment Share on other sites More sharing options...
