I feel about the same. I wouldn't ever be happy anymore with
2 Mags. Reliability wise I've actually had more worrysome
issues with planes over the years with mags than with the
lightspeed on one side. I'm not sure where those statistics
came from exactly, but especially with that last
Slick AD I'm not sure I'd believe them. Maybe Bendix
would be a different story. These days nobody runs
points and mags in a car....and even in my boat one of the
best things I did in the last year was swap the points
for an electronic trigger module. So one side has to be
E.I. for me.
But, just like Robin says, I don't know that I'd want to put
TWO of anything on the engine yet. If I did have 2, I don't
think the lightspeed would be my choice on the RV-10, because
you'd still have one crank sensor. And given the Looooooong
time to market and broken promises of pMag for the 6, I think
I'd want to see a few hundred flying, for a few 10's of
thousands of hours before I'd dive in. It wouldn't take but
a couple years for them to develop a track record one way
or the other...and I have to assume that if they were
reliable right now, they would be AVAILABLE right now, because
there certainly is a market for them once they are
released. I can only assume that it's because of issues
that they aren't making it to market...so I'll want to
see a track record before I'd go that route.
In the end, I'm very happy to have only 1 mag to overhaul,
but even happier that the engine runs best on that one
EI. I would prefer to keep that same type of
arrangement down the road...I'm not an "all eggs in 1
basket" kind of guy.

I would consider two different EI but not two of the same EIs.
I wish the 6 cylinder pmag were available (and fully tested)

Hey Danny,
Wow, I didn't know that was yours! yeah, Leon did
take good care of us. He had the closest unlocked
bathroom we could find, and then he drove us to get
a bite to eat. If it wouldn't have been for that
gesture, I wouldn't have made it home that night.
We were going to go for St. Louis and stop, but
decided to stick with the best "sure deal" flying
weather and scoot all the way home that night.
Funny you were in Utah...the other RV-10's
we were with earlier that day were headed there.
Another fun trip!

I would have liked to met you but was in Utah watching my daughter run a

Speaking of plugs...
I'm running the same iridium plugs I have been for so many
hours on the bottom now...Aircraft Plugs. But on the top
my last swap I went with the Denso Iridium plugs.
You can get them for almost the same price as the denso
W24EMR-C plugs that I got with the system now, since those
went up in price. (I know, I could save an by NGK or something)
But the iridium has worked good and you could probably run
those for 1000 hours with no problem. So that's what
I've been running now for a bit over 100 hours.
It is nice that they're cheaper. I don't mind the
iridium aviation plugs on the bottom though. I think those
actually provide the better value long-term too as
opposed to the massives...and they're certainly easier
to clean.

If you have one mag and one EI, do you run the mag all the time with the EI or is the EI sufficent by itself and the mag for backup?

I run both all the time just as if it was dual mags. I'm sure the EI would be sufficient, but I don't want it to get real quiet if one quits.

I have 2 of the smaller Oddysys batteries, and they have a separate wire running from each to 2 seperate circuit breakers, and then to 2ea. 3 position switches. (So they're totally independent) I can turn every component in the plane off, as well as both masters, and the Lightspeeds keep right on going. IIRC they can run as long as the battery voltage is above 5 volts.

You never want to intentionally run on one ignition system.... those are big jugs we have and firing on only one side for extended periods of time would no doubt put different stresses on some internal components. My 2 cents

I did the same thing as Marcus with the same rationale. I paid $100 for an extra coil and keep it in my tool bag.

I use them both just as would if you had two mags. Light speed has a very low-cost readout with a selector switch available that will show rpm, advance, or atmosphere pressure. While the mag is set at 20 deg BTC, I see the Lightspeed usually is around 30.

If you have one mag and one EI, do you run the mag all the time with the EI or is the EI sufficent by itself and the mag for backup?

Does your engine call for 20 degrees advance? I thought all the 250/260 hp parallel valve engines were 25 degrees advance.
The angle valve engines used to be 25 and Lycoming put out a service instruction to change them to 20, but don't think it applies to parallel valve engines.

Is there a consensus on the performance benefits of the electronic
ignition systems on IO540s in '10s (I guess that means Lightspeed)?
In particular, what quantitative benefits have been see.
I'm guessing that someone has done a writeup - link?

Tough one to provide a perfect answer. It's really about MPG.... and the MPG can vary a lot depending on winds. I have seen as low as 15 or as high as 24, but the 24 was at 11,500 with a great tailwind, gps gs of 230mph on 9.5 gph. Generally (no wind component) I cruise in the 17 to 18 MPG range. I have dual Lightspeed..
Just remember it's NOTjust about gph, it's mpg.
I can pull the rpm back to 2,000, the mp back to 16", and tell you I only burn 7.5gph.... but at what speed?

56% of all statistics are either wrong or made up... including this one.

I can confirm the accuracy of that statement.
However mags have an advantage. Electronic ignition has an advantage and Monty Barrett does not support stratling the two on one engine with the hopes of better horsepower.
Seek out a respected source. Ask about lightning strike redundance. On May 17, 2013 12:02 PM, "Robin Marks" <robin(at)painttheweb.com (robin(at)painttheweb.com)> wrote:[quote] --> RV10-List message posted by: Robin Marks <robin(at)painttheweb.com (robin(at)painttheweb.com)>

Just spoke to LSE regarding my box failure. The box had a dead power transistor (shorted). Upgraded electronic guts to later version and it's back in the mail. I received good service and fast turn around.
While I was at it, I asked about power consumption...
Box on, engine off: ~0.2A
Engine at idle power: ~0.8-0.9A
Engine at cruise power: ~2A
Good info to add to the POH.
Cheers,
Jay

LSE start engine on 1-2 blades and there's no discernible RPM drop between A&B sides during run up. Note that Plasma III boxes require forced cooling and ManP connections for spark advance. Separate wire runs for coax and sensor wires prevent EMF issues. Flywheel timing magnets are required (got LSE to do mine). Behind-prop sensor mounting bracket required drilling/tapping a couple of holes in the case. It turned out fine, but I puckered the whole time all the same. Proper connection of coax outputs to respective coil was an interesting exercise and resulted in a bit of learning on my part.
So far, I like 'em... with one caveat: Version "A1" box died at 14 hours while on the ground and just after engine start (my other box is version B). The good news is that redundancy worked as expected and the engine just kept right on turning. Wouldn't have have noticed until run up had the circuit breaker hadn't popped and warning LED illuminated. I checked the wiring, called LSE support and sent the offending box in for service. Will report back on whatever is found. Klaus has been friendly and helpful when I've had questions.
Cheers,
Jay

Well,
1st of all
let's look at all of Just the "Matronics Mail" sent in about Electronic
Ignitions within
just the last 2 weeks with "An open Mind"...
1) I never have to "Carry extra coils with my mags in case one fails"
2) I never have to "Open my oil door to let my mag cool off"
3) I can "Fly without any electricity" in my plane with my mags
4) I don’t have to "Face my plane into the wind to cool my mags" after any
flight...
5) Mags have at least a "60 year history of reliability"
6) I can get Mag parts (Points) at about any FBO,
Or
I can file them down,
Set the "Gap" with a "match book cover"
And
Make them work to get me home.
Try doing that with EI...
And last but not least...
7) I don’t need a "Backup Electronic Ignition" for my mags...
as is "Recommended my most A&P mechanics",
Most all articles written about EI,
Or anyone who has used EI in the past..
And all of that is from the last few weeks of "Matronics mail"......
Haven’t read much about "Mag Failure" in the last few years...Have you?
I read the stats in a magazine article about reasons why experimental
airplanes
Fail in flight or need emergency landings.
Yes it was on line, and from a reputable source...
The article was written a few months ago,
and confirmed my prior research on EI.
The article did mention than less than 5% of airplanes crash due to
mechanical failure,
The article also mentioned crashes or emergency landings were mostly Pilot
error.
The article went on to talk about engine modifications,
and it did address mags vs EI,
It said mags fail 8% of the time,
and EI failure rate was 16%,
Twice as often as mags...
"Don’t Shoot me",
"I am just the messenger"...
I will find the article and post it...
Now I was going to use EI,
but
I elected to have my
Bendix mag completely rebuilt and I also added "Shower of Sparks" to the
system.
For a mire $2500.00 or so.
I must report that they "the mags" and "SOS" have worked flawlessly,
For the 1,000 or so hours in prior planes that I have flown,
And also for the 90 plus hours on my RV-10.
Based in this "cool place" called "Las Vegas" (102 Tuesday)
And...
I never have (or had to) "exert any effort" to "Cool my mag down"
Even after the "hottest flight".
Imagine that...
N10KQ
Las Vegas Nevada
KVGT...

I believe your calculation is at least 50% low. ;-p
