Hi Captin'.
Your test ignition for your planes went out this afternoon. Please overlook the aluminum box it's in and concentrate your review on the performance of the goodies inside.

Thanks
John

Ben, give me the diameter and length of the sensor being held in the Delrin ring and I'll make you one. Easy to do.

John, The sensor diameter is 5/16th of an inch and sensor length is exactly 1 inch long. The entire length of the pigtail assembly from tip of sensor to the end of the pins at the connecter is 13 inches long. Sorry about the blurry photo but I was only on my first cup of coffee

John, I got the sensor in the mail on Saturday and it looks great. I haven't had a chance to install it yet as I've been up to my elbows in rebuilding a basket case trainer for a friend. Just about finished with it now and will try to install it and fire up the engine either Tuesday or Wednesday if the relentless frog stranglin' thunderstorms ease up a bit. THANKS for getting it to me in a most expeditious manner! I'll let you know how she runs...

Ben, it might be a few thousandths smaller in diameter than 5/16". This is the carbon fiber tube I use for most of that type application. Smear a little silicone sealer on it and see if it holds it. Most I make are just a tad loose so you can use the silicone to hold em in case they ever need replacing. Hope this gets you back in the air quickly.

John, The sensor fits and works perfectly. It slid right into the hole in the Delrin timing ring and just tightening the set screw secured it firmly. No silicone needed!

Great Ben...
I'm glad it fits the ring. Hope this solves your sensor issues now. Let me know when you get time to run the engine with everything finally replaced and working.

I may have some more units by end of august and a few spares built as well for future use. Started folding up some smaller aluminum boxes for the new setup with multi spark. As always, I'm flying one in my plane doing testing. So far it's been great with battery life. Getting over 2 hours on an 800 mah NiMH pack, which is a good bit of run time for my flying style.

Glad you liked the ignition. Actually I make them both ways. Aluminum box or like yours. Same thing inside both boxes.
Performance should be equal to or better than the old ignition which was made by RCxel. Let us know how it works out.

Thanks for the kind words Bass1 !
Working on the older CH ignitions is something I seem to do more of these days. While they were extremely reliable and well thought out designs, even the most robust designs can be rendered useless in a bad crash. Took a little probing and some freeze mist but found the problems and yours was up and running in no time. We all owe a debt of gratitude to Bill Carpenter for his life long work supplying us in this hobby with the marvels of CDI ignitions.
I for one, love the design. Easily repaired if you doink it in a crash. I can't improve on perfection, just offer new life for otherwise inoperable ignitions. CH designs were mirror image copied by RCexl a few years back, but there is nothing like a CH !!

By the way Bass1, goodies inside your returning box this week, couldn't help myself. Lol
Trial units for your next project!

John
I too agree...nothing quite like a CH.

Just a heads up on the differences that I’ve experienced between the CH (2006 vintage?, single edition) and the RCxel (2012, ver 2) installed on a Zenoah G-62.

Both the CH ignition and the RCxel ignition systems were tested on the same engine and in the same airplane without any changes being made to power system (e.g., same 4.8 v NiMh battery, JR mechanical switch, RCxel electronic switch, connecting leads, etc.).

Both resulted in easy starts and produced nearly identical top end performance 6,400 – 6,700 RPM. Likewise, both produced nearly identical idle performance – with the CH system being the slight winner when it could idle the engine down to less than 800 RPM!!! Yea, that's slower than I set it!!

However, the BIG difference that I’ve noticed, between the two systems, occurs during flight. Whenever transitioning from high or mid-range power to idle, the CH system is totally rock-solid and extremely linear throughout.

The RCxel system, on the other hand, hunts badly as it approaches idle speed and continues hunting throughout the entire time it takes the plane to slow to near stall speed. Once back on the runway, it idles steady. Not a biggie, but it is a tad disconcerting while trying to fly slow-speed maneuvers.

I’ve tried various gap settings on the RCxel pickup sensor and also tried altering the fuel mixture settings; however, the in-flight “hunting” still persists. I’m thinking that the RCxel mapping just doesn’t handle no-load conditions like the old CH can. That's just a guess on my part as I have since installed the RCxel on another plane also G-62 equipped, with the same results.

Update: Problem Fixed??? Flew the RCxel-equipped airplane a half dozen times this past week and NO problems with hunting! Tried three different props; PK 22 X 6-10; Top Flite 22 X 6-10 and a Zinger 22 X 10 all with the same result…in the air or on the ground the engine slows to idle without any hunting. Sorry folks, although I’m pleased the problem is gone, I’m at a lost as to say why.

got a few flights on the new ignition this weekend,can't complain about anything at all.starts easy,idles great(i think smoother than the rcexl),couldn't tell any difference in top RPM's,transtions from idle to WOT seems better also.
i am getting a better, wider spark,more blue and a louder snap.
GOOD JOB JOHN,your my new igniton supplier.

flyer55, I made a couple of videos of the "Black Box ignition powering a Asscociated Statioary engine. It worked real good with instant starts. For some reason the video will not upload to YouTube from Picasa like it did before. I will figure it out ASAP though. Capt,n

just have to give credit where it is due.John(AKA gr8flyer55) just sent a new Black Box ignition back to me. i fried the original one, i left the power on all night and after that i couldn't get any spark out of it.
sent it back to John and he sent me a brand new one,all i had to do is pay for the shipping there and back.
from now on he has all of my ignition needs,rcexl ignitions are a thing of the past for me.
THANKS, John
