"if I want them",
well, if you don't want it, I may need a rod or liner if they fit the 40s. ??

thanks !!!!!!!!!!!!

There is a very nice instructional video here on how to set the timing using a philips head screwdriver

This is the combo I use on CHI equipped engines, even on the FG 11, it makes an audible spark that cracks.

I Dave, I hope you are feeling good for Thursday !!

I have an Rx Ignition with spark advance that came with my modified Zenoah 20cc. I thought many times about marrying it to one of my FA100s. but I'm sure it doesn't have the spark a CH box has.

if any one wants to know why I bought this modified Zenoah 20cc. I bought it for a Heli. but the Heli kit had a lot of defects so I was pretty disgusted about it so I didn't finish building it and I sold it. and now I am stuck with the engine ! no one will buy it, not even half price NIB.

From experience: Your FA100 will absolutely not care that "it does not have the spark a CH has". It will just reliably fire and run on both brands.

Anyone looking for a 120 (some assembly required).

Parts from two or three different varieties off the 120's.

Already given away a few just like that one.

thanks for the info !!
I took the RX Ignition box out of the bag tonight, it seems kind of heavy. is the CH unit lighter ??
my FA100 I got from Dave. he had the CH sensor on it, will my RX sensor mount the same way?

thanks again @@

If the CH hall sensor that came on your 100 has a futaba connector you can plug it into your Rcxel ignition. They are wired the same.

Can't tell for sure because my CH is fitted in a boat such that I cannot get to it to weigh it, but I seem to remember that the weight difference between CH and RcExl is negligable, within 10 or 15 grammes or so the same, and I do not even remember which one is lighter...

I didn't get the CH sensor, I have not pulled the engine out yet to see if my Rx sensor will mount where Dave had the CH sensor mounted, maybe later tonight

OK, thanks !!!

Yes Jim, the CH unit is not potted so it should be lighter.
Noticeably lighter. Also, unlike RCexl, serviceable,

Saito ignition: made by Rcexl weighed in at 3.3 oz
CH ignition weighed in at 3.5 oz
Rcexl weighed in at 3.8 oz




Very rare for any of these newer CDI modules to go bad unless the user plugs things in wrong.

Jesse Open

Most service events are wires breaking down at or near the unit. The other events for me are the abilty to modify, such as a regulator rework in order to change operating voltages.

An option appreciated by some, if not everyone.

Weight savings are always welcomed.

Glowgeek

Yep, improperly strain relieving the power, sensor and tach wires can cause breakage. More user error. Easy enough to fold them over the box and secure with packing tape.

Regulator changes? Yeah, we boys at the field have catered CDI regulator swapping parties two three times a month.

Jesse Open

Well, not at the field, not here anyhow.
I do however repair electronics for others, often.
With CH, the boxes are very often easily restored to service. But I do the work at home, at a bench. Yep, pure overkill LOL!


The lead damage (including the HT lead) just happens over time for various reasons, but it does happen.

Your southern style parties aside, the regulator change ability is just one convenient option of many existing with the non- potted CH .
Among others, reverse polarity connections you mentioned are often repairable as well as the already mentioned wire connect repairs.
(Where ignorant people forgot to bundle the wires with packing tape, thus improperly strain relieving)

While most people do not work at that level, some folks appreciate the ability to place units back in service that for whatever the reason would have otherwise been tossed.


Nobody even hinted it as a " must do" as some folks like to imply. The potted system has its own set of virtues. Compare ifyou will and choose as you see fit.

Run what you brung is fine Some folks just "brung" a bit more.


Good luck at the field.

Gary, in your pic, those older CH boxes with the mechanical advance were all the rage in the day. Darn cool setup with being able to get rid of points and adjustable advance curve.

I do have a CH SyncroSpark module (Brown case) that may or not be functional, needs a sparky boot. If you can make use of it I'll send it your way.

Jesse Open

Sure Lonnie,

I get a kick out of putting that old stuffback in service. Thank you

1967brutus

So... 0,3 oz is about 7,5 grammes, give or take, right?

Jesse Open

Lonnie,

I am sending my address, check your PM.
Also, please forward your address.


Thanks for taking time to weigh your examples of the three sparky makers. The potting difference in this case is more easily measureable than noticeable.

Not nearly as noticeable as the differences between 15 and 30 degrees
