G-38 Conversion to CM-6 Plug?
I would like to convert my magneto equipped G-38 to a CM-6 spark plug so it will fit inside the cowl on a scale plane. I already have the adapter for the plug but the original plug boot does not fit the CM-6. Can the plug lead just be pulled out of the coil and the boot end replaced. Will the engine run ok with a CM-6 plug? Has anyone done this?

RE: G-38 Conversion to CM-6 Plug?
G 38 does not use a shielded ignition system and the CM6 plug is not a register spark plug.
You are asking for trouble trying to use a CM6 spark plug without changing to a shielded ignition system.

Agaperacingandhobby.com out of Richmond VA.has a complete RcXcel ignition that will convert your mag to ignition. This conversion is easy to do and will reduce some of the weight associated with mag ignitions. As stated above, you cant just change the plug, the whole assembly needs to be installed.

another option is to use a 5/8" hex taper seat plug like the NGK BMR6F.
by cutting off the threaded post and using a small conical spring in the cap to make contact with it you will come out shorter than a CM-6 with adapter AND it is a resistor plug.

Use the cm6 cap also use a silicon type wire.. Add a ring termanial to the other end.. Crimp it with the ring for the cap slid your heat shrink in place. Grind the eye to the engine.. Bit make sure you install your resistor!! Or do the electronic conversion..

After asking this question, I decided it was too much trouble. Bottom of the plug boot only sticks out about 1/8" and I need the hole in the bottom of the cowl for exhaust pipes and exit air. Left it original, with magneto etc. Starts easy and runs good. Decided not to fix what ain't broke.

You can install the 14mm to 10 mm Bushing in your engine.. Use the cm6 plug.. Use a cm6 plug cap with the resistor. To ground the plug cap use a piece of wire crimped to the plug cap! And growing it to your engine. It will work

Of do the recxell ignition cconversion. If you need a pic of what I'm trying to tell you here. Shoot me an email. Or pm so I can send you the pics of how it's done.

Also,
If you ARE going to convert your G-38 to electronic ignition don't forget to add about 12 ounces in nose weight to make up for the 12 ounces you will lose off the engine in magneto parts and coils!

If you send me an email I will show you what and how to make it work!! I have done it to several quadras. And never missed a beat!!
