Default E mag P mag reliability

My 7 has this set up currently. My other planes have always used magnetos for the obvious reasons. My plane has 300 hrs on a new engine and ignition. I have followed the manual during the annuals and have had zero problems. I was just posting the question to see if any other guys have had any serious issues with them. I do see some guys running dual p mags and I may change one of mine to have more safety and redundancy.

Default pmags @ 125 hr

Robb,
Mydual pmags have been flawless. There are many others with more hrs than me. But I have noted that my carb 0320 can get a couple of cylinders LOP without protest while taking data. Also, my MP / RPM / %power do not agree with LYC charts. I get 2500 with Catto 2 blade at lower MP than the charts. Could be the prop but Catto recommended for cruise because RV3 takes off short anyway.

Let's see - right now, I've got:

RV-3 - Dual P-Mags - 650 TT, P-Mags went in for four ware upgrade and checkup at about 500 hours - all fine. Had two corroded plug wires that were causing a misfire - replaced them.

RV-8 - Dual P-Mags - 1850 TT, P-Mags went on about 1400 hours, so 450 on them. Had a "fail-to-start" (failed self-test on power-up. Engine started and ran on one P-Mag fine, but caught the problem in the Mag check)on one unit very early on. It was a known issue that they adjusted for, and back on the airplane in a couple of days. Just had them checked up, no issues found, running great!

Dream Tundra - Dual P-Mags - 130 hours TT- No Issues.

P-Mags CAN fail, just like a Mag, or any other EI. EVen duel failures can occur, just like in other systems. I have found reliability to be statistically better (with a very small sample size) as Slick Mags.

The early P-mags had some major issues with both hardware and software.

They are now stable product, at least as stable as traditional mags.

However, it is recommended they be removed every year and inspected. You want to check the gear to make sure it is not gauling (There were some non-certified gears sold which have caused issues.)

Make sure your P-mags are on version 40 and you are good to go.

(I have almost 800 hours behind them and would never consider going to traditional mags!)

1400 hours on my dual 113-series Pmags installed in 2006. The first 200+ hours were pretty painful, numerous issues, but Brad and company got 'em straightened out and they've been trouble free for the last 1200 hours. Just sent them in last month for the V40 upgrades and general checkup, all is well...

500 hrs on dual PMags, no problems. Installed and maintained per factory instructions with no maintenance or reliability issues to date.

I'd do the exact same installation again.
