My RV7 has dual Pmags. I am not holding my breath on the 6cyd. model.

In my occupation, I get to hear all the bad stuff/ failures about not only our products, but also competitor's products from people using them in the field.

Do you believe "lost timing" and starting kickback events are acceptable on EI systems?
Ross,
I believe Brantel covered it really well.
Such comment from a well knowledgeable person such as yourself on the subject matter will sound like he is trying to misrepresent the situation especially if he is a competitor

PMAG has had its fair share of issues and no one will know if there are still some undiscovered issues, much like any other product. But their simplicity in installation and the self-powering makes it a tough competition for any EI. But that is not to say that this is the product for everyone.

I am sorry for the loss of your friend. Reading the report however suggests this was not a PMag issue. The mechanic who did the install had never done one before. He incorrectly wired the Pmags to a common power source and after installation all RPM indications were lost. In addition it appears extensive work was done on the alternator and that it was inop for the flight and flights before. He was flying on battery only with no RPM indications on PMags. Not a good combination especially when known before flying.

I didn't dredge up this 2017 thread and nobody disputes that Pmags are about the easiest EI to install on Lycomings and that lots of folks like them. They are probably currently the top selling EI for 4 cyl. Experimental Lycomings on the planet. I'd also say that things change in 2 years. What might have been valid in 2017 may no longer be...

There are numerous choices of EIs these days and people can buy whichever one they like.
