Bill Percival Posted April 27, 2021 Share Posted April 27, 2021 Anyone out there flying with EMag P models? Did you do anything special for cooling? Installation manual calls out blast tube cooling, but with our updraft cooling providing some flow in accessory area, don’t know if it’s necessary.

macleodm3 Posted April 29, 2021 Share Posted April 29, 2021 My mid-time O-360 came with P-Mags which I removed and sold to an RV builder. There seem to more problems with P-Mags on our pusher canards then on other aircraft designs, and a common problem was that one P-Mag would fire the plugs at the wrong time, causing the engine to produce no power. In a more typical magneto or EI failure, the other ignition keeps you going... but if an ignition fires at the wrong time then you may lose power. To me a loss of timing failure is like losing both ignitions... Some canard fliers do use P-Mags with success... here is a link to how Nick Ugolini cooled his P-Mags on his Long-EZ (which I think he has sold). http://nickugolini.com/blog/?m=201801 Andrew Quote Andrew Anunson I work underground and I play in the sky... no problem Link to comment Share on other sites More sharing options...
