Does a G62 Electronic ignition require a different sparkplug than a G62 Magnetio ignition or work better with a different sparkplug?
I have checked the engine forum for this question and found nothing. Thanks for your help.

Doesn't matter. Use the stock plug.

Any resistor plug will work, as long as it'll screw into the hole.

RCJ6Y or RCJ8Y

I use NGK BPMR7A in all my gas engines. It produces a powerful spark whether its 40 degrees or 90 degrees. I change all the sparkplugs every Spring and never have a problem.

When running a battery powered ignition, the spark plug is a little more important as you need to run the one that fits your spark plug cap.

Some of these have a bigger ceramic insulator.

The correct plug of choice is that mentioned in the previous post. NGK BPMR7A

or Champion RCJ7Y, Be careful about the insulator on some of these . . . AC CS42S, Autolite 2974, Nippondenso W22MFV, Bosch WRS5F . . .

Is the NGK BPMR7A the best performance for a G62 Electronic (battery) ignition or for a Magneto ignition?
I noticed for the G26 magneto ignition it uses a Champion RZ7C (CMR7H) and the G26i Battery ignition that one uses a Champion Y82 (CM-6).
I wonder what the reason is?

To my knowledge, the G62 doesn't come from Zenoah with electronic ignition.

You have to put the RCEXL conversion on the engine and it uses the BPMR7A I think.

Bosch WSR6F, NGK BPMR6A, Maybe Champ RCJ7Y.
I said maybe on the Champ because I have seen 3 different lengths of porcelain on the same part number plug. The metal caps will only fit the shortest

Original mag G26s used a RZ7C 10mm spark plug..The EI for some reason uses a CM6...

Which Sparkplug would you recommend for a G62 Electronic Battery Ignition? Thanks

Champion RCJ7Y..Comes with all new G62s
NGK BPMR6A
Bosch WSR6F
They work equally well...

The NGK plugs with the "F" on the end are Tapered seat.

The NGK plugs with the "A" on the end have a gasket seat

I have swapped these back and forth in some engines and couldn't see any difference in performance or compression.

Thank You both (w8ye and Antique) for shedding some light on my question.

The RCJ6Y is colder.

The RCJ8Y is hotter.

I use the RCJ8Y at high altitude with 91 octane gas thats got 10% ethanol in it. I would like to find "real" gas, but I don't think it exists in Colorado. The hotter plug and higher octane gives me a couple hundred RPM. I'm not saying that will work for you. It works for me, flying at 6000' altitude.

I have both the G62 on a mag and one on ignition (C&H) and I run the Champion RCJ7Y. This plug in a mid heat range plug (between the cold 6 and the hotter 8) and the plug works well for me. I used to live and fly in Denver and I now live and fly in San Antonio Tx and still use the 7 and have never had any plug problems.

RC pilot:
You noted you would like to find a "good" gas. When I lived and flew in Denver (1990's), I would got to Jefco airport and buy 100 low lead avgas. I still buy and fly the 100 LL here in Tx and I have never looked back. The current price here in San Antonio is about $4.35 per gallon. It is a little more than you would pay for premium but I think it is worth it. The av gas has no smell so when I put it in the back of my truck I don't get that gas smell that you get from auto gas. It also has no ethanol. If you stilll want to go with a non aviation gas, Power Master is now selling pre mixed gas for model use. Power Master was recently purchased by Alllied Chemicals (they make the VP auto racing fuel and a lot of the Nitro used in this country) and they have invested quite a lot of time and money for this new line of fuels. I only know this because the distribution center for the fuels is in the San Antonio area and I get to talk to the sales people periodically. They have started advertising in a number of model mags so check their ad for the website.

Just my 2c.

Do you think this may be that the EI unit uses a metal cap verses the Mags rubber boot?

Metal caps are made for any of the sparkplugs....RC EXL can be ordered for any plug, and Bosch caps fit on the RCJ7Y and NGKs....
