Emag/Pmag My Experience
ECI IO360 with Whirlwind 200RV Propeller. One Emag one Pmag.
Set up and installation was very easy. I used a 5 amp breaker for the Emag and a 5 amp switched breaker for the Pmag. Timing took about 10 minutes total with another 30 to get everything locked down.
As of today, I have 52 hours on the plane and the system has worked flawlessly. This is an extremely smooth combination that I'm very happy with. My cutoff point on the Pmag is 680 rpm, well below the 850 rpm I have set up on the engine. I have had no CHT issues at all as some others have described.
The only real issue I have is during a mag check the Pmag drops 160 rpm while the Emag doesn't drop. The Pmag drop is consistent each time. I have checked all wiring and did in flight checks and all seems fine. I plan to send them in for a "once over" when I break down for paint
Regarding, the supply and delivery, I was given a time frame in which they met. I was not ready for them when they were ready to ship. I told Brad to ship them to someone who was ready and slide me down on the schedule. I got them, when I was ready, a couple of months later.
This is a new product. Other than a few isolated performance issues, I think that these have as good of track record as any other new product. (Dynon comes to mind in the early days). The important thing is how issues are handled. Brad is responsive and committed to having the finest product available and eventually have some on the shelf ready for delivery. Most importantly he is communicative and not afraid to admit the delivery shortcomings.
I'm having great luck with mine. I sincerely hope they get the delivery issues worked out so more of you can experience the simplicity, ease of installation and performance of the Emag/Pmag system.
