Default G20 stock ignition versus RC exl system

Does anyone have any first hand information as to wether both these ignition produce very similar rpm results or does one have a noticable performance edge over the other.

Primary difference is battery draw. The Zenoah is 2-2.5 amps at WOT, the RCexl is under 400ma.
The power diff is not much, but instead of gaining power you can lose weight to gain performance

Would a 'true' politician have been that honest ?

A 'true' politician would never simply say "No", that's what I understand of 'politicians'.

Btw, I'm going to replace my faulty g20ei CDI with the RCexl CDI that came with the DL50 soon. I wonder if this CDI will work with the stock g20ei hall sensor. There would be much hassle to modify the bracket to mount the RCexl hall sensor if I were to replace the stock sensor. Has anyone had experience in this setup and care to share?

Match the colors on the sensor wires to the RC EXL unit and the stock Zenoah sensor will work.

Thank you for the guidance.

I emailed RCexl and it was comfirmed. Just match up the colours, ie red to red, black to black and white to white.

I switched and would never go back to the original Zenoah junk. I run a 1100 mah pack now. I would just install the new bracket, since you now can adjust the timing like all the rest.

If anyone wants to get rid of a Zenoah ignition...I could use a few on my staionary Low Speed Model Hit & miss engines. The size of battery does not matter....they do not get off the ground and top RPM is maybe 200 RPM!!! Best Regards Capt,n P.S. I will pay the shipping!!!

timing is timing, you aren't going to gain any power other than from the lighter battery you get to carry around...

Anybody else wonder how Zenoah missed the mark with their electronic ignition. What does their module do differently to consume so much power? Just doesn't make sense to me.

So you can use it as a hand warmer during cold wether flying (High Drain = Heat).[X(]

hi all

G20 hall Sensor may retain and use RCEXL ignition.

Only That means white connect to white, red connect to red and black connect to black.

Well, it works.

I tested the RCexl ignition module with the stock G20ei hall sensor without adjusting the timing angle, the engine ran normally and smooth as before. The battery was 4 cell x 1.2 nicad. Everything seemed fine and I am satisfied. Thank you RCCDI and those who have helped.

they didn't miss the mark, the zen unit is a true high perfomance electronic igniton, its capable of 30,000 rpm and water proof,none of the others can do that, the rcexl burns itself up over 14,000.
compare spark voltage, amperage, and duration and you might find the difference.
Carry 2 or 3 charged packs and swap out the drained packs, whats the big deal?

So you have a 30,000 rpm ignition teamed up with a 10,000 rpm engine. An this accomplishes what???

It is also water proof just in case you dork it in a lake somewhere.

Milton,
Maybe it will go beep beep too so that you can find it.

yup rc xtreme got it... a float plane


You  aren't comparing apples to apples comparing the rcexl to the zen unit.It doesn't make sense to spend the money on the engine with the factory EI and then spend more money replacing it. Just buy the proper lipo set up from Tony Clark.The right battery on this EI unit makes a world of difference.


So you have a 30,000 rpm ignition teamed up with a 10,000 rpm engine. An this accomplishes what???
You have to realize that zen makes engines other than for airplanes and a single engine series will be adapted for multi purposes, the G26 comes to mind, there are 3 versions of it, airplane,heli and boat.
Did it ever occur to anyone maybe they designed an EI unit to could cover more than one category so they don't have to waste money making 3 seperate versions?
The G20 is not  a 10,000 rpm engine,the boat guys are zinging it to over 20k rpm.

If you are going to dogpile the zen EI, make sure you are comparing it to another unit that has the same capability. Again you  aren't comparing apples to apples comparing the rcexl to the zen unit.
 Is simply replacing the ignition battery when its low  an impossible task?I can see your concerns on those transatlantic flights, but circling the flying field it shouldn't be a problem.

Your argument for the Zen ignition has some valid points, but I think you are missing the boat somewhat as most times the unit is dogpiled not because of it's ability to perform but rather because of the inconvenience using it causes. For me having to dismantle my model every two or three flights to replace a used battery is not my idea of having a fun time at the flying field, but then again that's just my thinking, plus I don't do lipos.

The RCEXL,CHRCXLand CH ignitions DO NOT burn themselves up at over 14000 RPM.With our new Heavy duty spark coil and dual transistor ignition module I can make lightning with a 1 amp currant drain,Or you will think its lightning if you get a hold of it.We can put out 40KV all day long and unit just gets a little warm.,at 24000 RPM.With less then a one amp currant drain.The Electromotive engineer who designed our new RPV spark coil has had one running for three years continuly with a 30KV output and 3/8 inch spark gap..Its a little overkill but you can buy this Igntion for your Gas model.
I love the Zen ignition ,we sell a lot of replacement ignitions. Our CHRCEXL can be built for two li polys and will have about a 350 mill battery drain at 8000RPM..No regulater.

To back up what Bill is saying I routinely run my gas/spark converted Supertigre 51 over 15,000 every time I fly it.  Never had a single ignition issue other than a fouled plug which happened at 35 hrs.  Second plug at another 38 hrs and it's still on the third plug.  That's a lot of hours at 15,000 and no probs.

P.S. I race club 40 pylon and this is a good practice plane which is why I run it at WOT so much.

Our testing has shown the only other ignition comparable to the Zen unit is the Runtronic, the rest don't last at high rpm. If changes have been made to the RCEXLEIunit since January I'd like to know.
If the "new"RCEXL can last running 24,000 rpm and is water proof, then I'll consider one.
The condition of the http://www.rccdi.com/ website is not confidence inspiring though.

but I've been told I don't need this capability or that boats don't need EI and can just use the mag set up, but its mostly coming from people who don't run boats and aren't familiar with the problems with the zen source coil and the ignition coil dropping dead and the high cost of replacing them, especialy the source coil.
I don't just build engines for flying, but for boats and buggies also. Theres more than one application for these EIunits than just low rpm airplanes..
