Mags to EI

[RV10@boyercreative.com]

Ok, I'm opening a can of worms but I'm at a crossroads and have no choice. My left mag on my -10 has a stripped shaft and nut. The only thing holding it together was the cotter pin! Thanks Mr. Kotter! I was hoping for the Pmag solution but they aren't releasing (if that is true) until end of Aug and I'm not even in the "first wave." As a result I have to find a different solution. I can either buy a new mag (which I hate, Just flushing $$ down a toilet) or I can go with a different solution. What I have really disliked about other solutions is I REALLY don't want to have to manage a second backup battery.

So..... blast away. I really would prefer a dual setup. I would really like the tractor parts to go away.

Frustrations galore,
Richard

You didn't mention if your current setup was with Bendix or Slick mags, but if you currently have Bendix just buy a rebuilt mag and be done with it! You're not "flushing" anything, just performing maintenance on your engine.

If you're going to EI, take a look at the SDS products. I really think they have an edge over all the other systems offered now. Least expensive, C/S if fantastic and I don't believe there is a reported failure yet.
I'm very happy with mine after trying 2 other systems.

There is no hard requirement for a second battery if ignition is your only problem. The SDS CPI -6 pulls less than two amps per system at max RPM. The more realistic 3 amp total draw for a dual CPI system at cruise power should get you several hours of flight with the existing ship battery. In such a scheme it is easy to hard wire a dedicated circuit direct from the battery (with an appropriate "Emergency" switch) that allows you to dump the master but keep the engine running.

There are plenty of threads that discuss schemes for achieving airliner dispatch reliability, but only you can decide what is required for your mission.

And good on you for dumping the tractor parts!

I have slick mags. 1100 for a replacement doesn't seem like a good solution unless I'm sticking with mags.

You might run your mag problem by Arron at Select Aircraft Service in Lancaster Tx. 972-227-9580. You may be able to get your mag repaired/overhauled for a reasonable price while you wait for a EI solution. I used him for the first time last month and was pleased with the outcome and price.

With one mag and one EI, would a backup battery be required considering the mag AND alternator would have to fail to need it?

...and the primary battery.

A triple failure is a bad day indeed.

Agree. SDS CPI, user-defined dual ignition maps (one for ROP and one for LOP), via the supplied control head.

If you tend toward DIY, consider an EDIS-6 and a Megajolt/E controller, which is also dual map, user-defined via laptop.

Go look at surefly, I have not installed on my rv10 yet but my neighbor has them on his rv10 and is happy.
