Guys,

Why would you be putting di-electric grease, vaseline or other such into the plugs?
If you have misgivings about those plugs, why not just decent quallity Deans plugs or similar?
Or better still, just use the supplied ones with security clips?

... You would be better off using Vaseline for the purpose you described.

Would KY Jelly work ok, I think the latest is pure silicone.

Toe jam works too!

However, after a while you need to wear a dual air filtered respirator to remove the hatch.

So my results from Hitec and JR is that there is no difference in the connector from a standard servo to a top of the line digital servo. Some standard servos use tin plated connectors, however.

This is what I thought

Yes, I knew this, but I thought I would ask the manufacturers to have something to type this afternoon.

I had some erratic engine running this past weekend. Turns out the sensor of the rcexl went out. First ignition issue I have had ever.

How is a security clip going to stop corrosion? Capt,n

Gold does not corrode which is why they use it for contacts. Unless you are flying from water I see no need for using grease or vaseline on connectors. I also seek to minimize extensions. What isn't there cannot cause problems.

I got a neat idea how to view the spark under pressure.  The set-up begins with a wore out cylinder jug.  Details tomorrow!  Capt,n

I saw one in a video somewhere. They have a chamber with a plug in it and a window. They pressurize the chamber to check the spark. The plugs were perpendicular to the window for easy viewing.

We used to have one that you could check the spark under pressure and also clean the plug at the same time, That was about 40 years ago.

Was at a garrage sale about 6 months ago and seen one, Should have bought it.

In the mid 60's I had a 427 Ford and it would foul the BF-32's left and right. Those Champion plug cleaners were gone from the garages then. I went out to the airport and they still had one that I would clean my plugs in.

I think JC Whitney still sells a sand blast plug cleaner you hook up to your air compressor. Problem is you have to be sure to get all of the sand blast media out of the plug or it gets in your engine. maybe you could use ground black walnut shells, or maybe even dry ice to blast them. Also since you may be rounding the edges of the side electrode a little with the abrasive, you should file the edges of the side electrode to have sharp edges for good sparks.

Totally agree!. I only did it when my MG Midget would foul it's plugs on a daily basis. I would have a cleaned set in the car and change them roadside as needed, then clean the fouled ones that night at home. "Fill up the oil and check the gas" back when they did such things for you at the gas station.

I should have said a way to "check the spark" that is put out by the RCEXL ignition under pressure, with the ignition this thread is about. That way you can compare the spark out-put of each CDunit. I Have 4CD units, 2 that are RCEXL. I can make the pressure chamber with a used jug and mill of any ridge where the cylinder bolts to case. This will allow to bolt down a 1/4 clear Plexiglas for the window. The intake & exhaust can be covered by metal plates using studs or short bolts. I will post a photo of the set-up so far. Capt,n

Mainly used to compare quality of spark of a CD unit under pressure. I have tested brand "new spark plugs" before that only fired up to 32 50 PSI. Not Good

Out of curiousity, just what do you plan on doing with the information obtained in your tests? Sounds like a lot of time and effort for only enlightenment.

Already did what you are about to embark on with a comparison between NGK and Champion plugs. Controlled environment of course. The ignitions work.

Default RE: RCEXL company Needs to get Involved

I have 2 RCXEL ignitions. I ran the spark test under no pressure. There seems like a bit of difference in quality of spark...swaping only the CD unit...takes abot 30 ceconds. Same everything else. It just seems like to me that under air pressure....one my be not so good as the other CD unit.

There is no critical machine worl...even with poor eyesight...I can do it. Iguess I like to run my mill...while I can. Also the Lathe. I made some custom sleeve brg for my new wheels. The other ones was sloppy (from new) now no wobble and they spin nice.

Tom, If you can give us a more detailed report on your pressure testing of CD units and spark plugs. I wonder how the four plugs I have compare. Ngk...Denso...Dle..and Honda Do any of the CD units vary in the quality of spark....with the same brand? Thanks Capt,n

I have never had problems with these ignitions. They're great.I agree that much is user error mostly battery choice. Or bad battery.
DLE recommended products : 6.6V LiFe packs( 7.2V full )
CDI case 4.8 - 6.0.... in my opinion 4.8 servos or any CDI should work on a 5 cells pack with no voltage regulator www.dle-engines.com/dleg0020.html

Better watch running 7.2V on all RCEXL iginitions. Some older ones will not take more than 6V

"Ngk...Denso...Dle..and Honda Do any of the CD units vary in the quality of spark....with the same brand? Thanks Capt,n"

I'm only going to scratch the surface with this, then no more.

NGK and Honda, same plug. Denso, NGK/Honda similar in performance, which is quite good. DLE...hmm, I wonder if they even know who makes those things.

Differences in same maker CD units? Sure there are, but I'm not going to identify because 99.9% of you don't use them. Very minor fluctuations happen in just about everything because nobody uses MilSpec components. Lots of variation in off the shelf stuff, especially in minimum cost production components.

And then what happened? Was it a bad plug that sparked internally? Or was the ignition faulty?

What happens is the plug arcs to ground from top to bottom at the outside of the plug. When they fail at chamber pressures that's what is happening. Part of the problem eminates from cap designs.
