Status: offline 		Most Ingnition Failures are self induced and the same holds true with the glow engines. Most try to peak a glow engine on the ground take off and a few minutes later have a dead stick or a flight or two. Getting a glow engine to close to peak rpm on the ground results in burning out the element in the plug. Glow engines are the most simple engines to start there is. No matter what size. All my glow and gas engines when set properly start as easy as this one in the video

Status: offline 		I only have 4 gas engines and they don't have loads of time on them so I may not be a good data point but I have had no problems with the name brand or the no-name ignition units. No failures out of the box either.

I can vouch for glow plugs lasting for 8 years. Maybe glow plugs are different from what they were in the old days. While It is true that my flying time is divided among several planes, I put a lot of time on them and I know for sure that I have not replaced a glow plug in 8 years. Some are run on 30% nitro.
I've observed experienced modelers leaning glow engines to get the very last RPM out of them on the ground then wonder why the plug won't light for the next flight.

Glow engines start easier than gas engines. How can they not start easier, they are very simple. I'm sure you can get the impression that glow engines are difficult to start when you watch someone jam a starter cone against a spinner on the first start of the day and spin and spin until their wimpy 7Ah starter battery sags. Doesn't it ever occur to some folks that glow engines, like gas engines, need to be choked to get the fuel to the carb?

I generally hand start my glow engines and yes after the initial start of the day they can be started by snapping the spinner in reverse rotation with your finger tips.
I've never used a starter on a gas engine even though it takes more flips to get them started after you get them properly adjusted. I don't consider them to be difficult to start, it just takes a few more flips.

I could hear a high pich sound comeing from the control box. replaced it and no issues since. I only use 4 cell Nicad packs for the control box. I have 6 diffrent other gassers with no issues.

I guarantee you that you will spend more on glow plugs than what will be spent on ignitions.

So very true a statement as in the 10 years that I have been flying gas I have had only one minor ignition issue, which was quite easily fixed.

I'm going to try to convert my MLD-28's to an RcExcel Ignition and see what happens.

When gas engines are working they are really great. No comparison on fuel costs. When problems come along they frustrate me much more that glo though.

To date on those who responded YES on failures made up 40.2%, with those answering what type failure 75% were ignition module failures. Hopefully if some mfg. rep reads this forum they will look into why there is such a high failure rate. I really like the idea of gas engines, their sound, performance and low fuel cost but it doesn't seem like the ignition reliability is where it needs to be. By the way in the last 5 years of using four strokes I've replaced only 3 plugs.

I think a better poll would be to ask what brand ignition had failures, The problem with just asking about ignition failure is there are are some Asian made engines being sold that no matter what the end user does they are going to fail, Most of these are made by the same company that sells the engines.

Like I posted here earlier I have had maybe at the most of 4 ignitions returned to me in 3 years from product failure.

The RCexl ignition has proven itself to be the best ignition you can get next to the original CH ignition.

Status: offline 		After reading this thread I can't help but notice that most of the yes answers were using off brand systems. I have been flying gas for over 10 years and have had only one failure and it was my fault.
It was on a old 3-w. I believe it was a blue dot. I used a 6v battery. I had another one and have been using 4.8 and for the last 6 years it has worked fine. Dennis

Status: offline 		I would have to agree with Milton here based on 20 years of playing with gas engines. With 6 twins and 4 single cylinders in the mix I have had one failure on a CH ignition that had 7 years of continuous service and it was a connection failure between the coil and the high tension lead not an electronic problem. I have loaned a spare RCExcell module to a friend to replace a problem unit that he had with an earlier unit furnished on a Black Canyon G-62 but that is the only RCEXCELL unit that I know of that has had a problem and again it is several years old.
Most problems that I see are damaged plug boot connections and bad switches and cutoff units not the modules themselves. Since most of my collection is DA, Brison Zenoah and Taurus, I can't speak to the reliability of the other systems but I would put the overall all reliability as high as any of the considerable number of large displacement glow engines that I have operated in these same years.

Status: offline 		Thanks for the good info. The reason I asked this question is firstly I don't know much about gassers and over the past few years what I've heard from friends from all over is " If you buy XYZ (China brand) you may as well get another ignition because the one that comes with the engine will fail in no time".

The other day another club member had trouble with his North American engine that he just got back from the mfg. as repaired ( Hall effect sensor replaced) and told that it ran fine in the shop but wouldn't hit a lick the first time he tried to crank it at the field. We changed plugs to a new one and connected the battery directly to the module. These guys have been flying gas engines for some time and have had ignition troubles with all of them. It makes me wonder if these modules are all made by the same few companies with different logo's stamped on them. The poll was just a way to see if module problems are experienced by gas burners around the country.

Thanks for all comments and who knows, discussing this might point to some mfg's more troublesome than others and may save someone some bucks to boot.

One day when tuning a Webra blackhead I burned up my 5 spare Enya #3 plugs. Bad plugs? , bad engine? My bad?

Did your friend have any trouble getting the timing correct? The MLD Ignition fires with the magnet in a different position than the RcExcel. The timing was too far advanced with the RcExcel sensor mounted on the stock sensor boss.

I did get a new Rcexcel sensor holder that has much longer arms. I am going to try that.

I have had a lot of ignition issues with those engines. I have 5 of them. When all is well they run great though.

Status: offline 		He had just gotten the engine back from the OEM, repaired with a new pickup and told that it ran fine. He installed it on a bipe and took it to the field where it was cranked for the first time since getting it back. We replaced the plug with a NIB, connected the battery directly to the ignition, used different batteries, took the plug out and grounded it while turning it with a starter. No fire at all. I haven't seen him since (2 weeks) so I don't have any more info.

+1 on this. Old thread I know but my MLD28 engines now run like watches with RcExcel Ignitions. I went thru more than a year of failed ignitions not realizing it was the ignition. I changed carbs, batteries, switches. Once I installed the Rcexcel on my two engines they ran perfectly. Also had an ignition fail on a PTE36 after an hour and a half of run time. The RcExcel was a direct replacement and fixed that one too!
