Can anyone recommend an after market EI system for conversions. Is their a inexpensive system that can work for many engines, basically for testing. Is CH the best choice in value.

Get one from Ralph Cunningham...last I knew he was able to pass on the best deal, for a REALLY good ignition:

Yup...get that ignition from Ralph.....best service you will find...and very good prices!

Not getting an answer on the phone number-could you please check that-Thank-you

Ralph has been out in California for a week.He just got back last week.Keep trying.Probably better in the morning.

I have been using the XYZ replacement ignition from southeastrcengines.com. Have one on a Ryobi 31cc that works great so far. Only a few flights. But price is good. southeastrcengines.com

How did you set up the hub?

Hole saw the flywheel?

Heres a pic of my 31cc ryobi i just did.I also put the cylinder in my lathe to round it out some for a more finished look.Holesawed flywheel.3-1/4 lbs as in the pic with ign and mount.Rcexcel ign.Just drilled and tapped 6x32 in the front case for sensor.

If a person has a aircraft with a standoff box on firewall...you could just use a flate plate of aluminum to mount the Ryobi. Also a light muffler built from a aluminum beer bottle. Lots of options!!! Capt,n

Yes, I used a hole saw to cut out the flywheel for the magnet hub. To mount the sensor I epoxied the sensor to a screw hose clamp then mounted the clamp to the crank case.
