In a previous airplane I had I had the lightspeed electronic ignition with a dynon. I kept getting a stumble it scared me since we couldn’t troubleshoot the issue all the way. Took off the lightspeed and put a mag back on and never had any issues.

I have goosebumbs from head to toe just at the thought of seeing this plane! My Dad built aircraft during the war, and instilled a love of aviation in his family. He was an Aircraft Engineer working for Air Canada for the balance of his life. He lived planes and this was a favourite! He participated in aircraft restoration after his retirement.

Hi from across the lake near Rochester! My flying journey's been on hold a long time but you're inspiring my wife and I to get back to it. Being scout leaders, we are very familiar with survival or bug out bags. Very similar contents and thinking. Your comment on maintaining your mental health is right on. I try to keep a deck of cards or something small and portable to keep things fun. Of course, food is always a winner. 2 things I'm taking away from your kit is the cup noodles and the gloves. I hadn't considered bringing cup noodles because of the volume but I'm going to look at that. The additional containers could be worth the space. I think the gloves are really smart so I'm going to add those. Love the videos, hope to meet you one of these days. Take care!

Great to see it flying still. I seen it when it came to the museum and many many times flying, to great she is still doing her thing.

I'm no pilot, no nothing about plans, but still watching all this with rapt attention and wondering why can't you test the engine on the ground?

Nice to see 4532H. I owned that plane (literally that exact plane) for a few years around 2010. So great to see it in good hands

I didn’t hear what type of plug you were running. Massive electrode plugs seem to be more reliable than the fine wire. Sometimes moisture gets in front plugs and leaves carbon tracking on insulator. Make sure that’s cleaned every time you work on plugs. A minor consideration is the engine was designed for 80 octane, 100LL causes havoc in these old engines.

Lancasters just sound like freedom to me. But back in the 80s and 90s I got talking with some vets and even got to know a couple of pretty good, but I only recall one name now after so many years. I got to know a George Hutton from around Barrie Ont. area who I got to work with for several months and wish I reconnected with him later on because his advise was rock solid. I know in 90s some others thought he was as tough as nails, but he just wanted the best for everyone, but he loved a good story and laugh too. Thanks for the memories!

Interesting video. Thanks for posting. I grew up near the Oshawa airport and I recall hanging out there as a kid in the 70s and there were WW 2 tanks there, and, of course this beloved Lancaster parked there for years. Is this the same one? If not, what became of the Oshawa Lancaster?

I had a stumble on my C85. Ran great for 2 years then a stumble. I always run 1 oz Marvel Mystery Oil in 20 litres of fuel. Plugs are always clean and I check the spark plug resistance every time they are out. 500 to 5000 ohms is a good plug. I decided to try MMO in the oil. I now run with 1 oz MMO per litre of oil. Never again has it stumbled (over 100hrs). Plus I also use Phillips X/C 20W50. Great job troubleshooting!

I appreciate your content.. I do think you should frame this video from the prospective of how great it is to have logging and digital instrumentation.. The audience should understand that this is not required to solve this problem.. It’s an o-300 with a failed or fouled lower plug..

I am a pro in polishing llo soi un motro En eso .

Cool channel. I enjoy the thought process (of elimination). Had carb ice on final once................won't ever forget carb heat again !!!!!

Had a similar issue and was a cracked spark plug like others have said. I did switch 4 years ago to Tempest fine wire plugs and highly recommend them. They are expensive but last much much much longer. There are so many benefits! From leaning, easier starts, no fouling, more complete ignition and more! Worth every penny!

anything to do with time of day flying?

did you ever get new instrument panel installed?

The aircraft that sent chills down the spines of The German Reich. Amazing piece of history, we owe our freedom to them and the men that crewed her. ✌🏻🕊️

Could the case mag be going bad or was it just plugs? We had an old case farm tractor that apparently uses the same mags as aircraft and they would occasionally go weak. My boss had a box full of them and we'd just swap them out. He had 4 brand new ones, new old stock that we weren't supposed to use plus 7 or 8 used ones. The boss figured use the old ones till they just wouldn't fire at all before using the new ones.

The only thing more frustrating than an intermittent fault is an inconsistent intermittent fault! I just about went nuts when a major new packing machine was installed at work and every time I did the prescribed steps to start it up it did something different. The machine was new to us and new to the technicians who installed it, and three different suppliers were involved, so lots of finger pointing! There was no blood and nobody died but it took it's toll!

😂😂lol Glen makes a pretty nervous co-pilot. 😂. He'll make a pilot out you one day Jules. 😂 That Lancaster is such a beautiful old bird. I remember as a kud watching the old war movies with them in it. So cool.❤

Check dew point and temperature on day of hiccups. I have been flying since 1975 and never had Carb Ice issue. One day on a routine summer flight after bouncing cloud bottoms the 0-320 shuddered. I pulled on the carb heat and it stammered and sounded like an ice machine. I diverted to the nearest airport straight in landing as the engine quit totally. I coasted off onto the ramp and phoned for a ride home. After sitting 45 minutes it started and ran flawless.

You have a tent in your hanger? Camping there or drying it out? Just curious. Great video!

I am not a pilot or mechanic. I don't see why airplane engines are so sensitive-fragile-trouble prone. I can understand the need for extreme safety. My 2011 Honda Odessey got 100,000 miles on the first set of spark plugs and have 60,000 miles so far on the second set. I'll remain on Terra Ferma. It's a lot less expensive.

If you upgraded to an electronic magneto system, why are you still running an antiquated magneto (Henry Ford would love it)? I’m clearly missing something here.

G,day Glen from Sydney Australia. OK Would have been nice to put a borescope in the cylinder (6) and check for; * Color rings on piston head * Seating of valves and discolouration * Wearing of cross hatching on the cylinder wall. 😇🔥

An indication of a weak mixture on the new cylinder screams to me an air leak With the engine running spray carb cleaner round the new jug if you hear an increase in engine speed you have diagnosed your problem (Seating of new jug in engine casing ) ? Great video

Hi Glen! Just FYI. On my o300 I had a similar stumble that was intermittent. Eventually narrowed it down to a cracked spark plug....that would test okay....but under heat and stress every now and then would hiccup. Changed out that plug and smooth running

I've had this with a sticking valve. If that's what it is, it will typically be also be apparent shortly after start up (rough running) and then smooth out as the engine warms up. I've chased that with one of my cylinders have it reamed twice now. Very recently I've had two occurrences of rough running at top of descent if I reduce power and rpm. Upon inspection of my engine monitor data that one cylinder clearly has a noted drop in EGT at the times it ran rough. Getting estimates on replacing/overhauling that cylinder. Nothing like a rough running engine in flight to pucker you up!

safe travels....must be bit concerning

I hope you've gotten it all tracked down, trying to figure out intermittent stuff in an airplane is no fun.

Was it clear from the start that the stutters were a cylinder not igniting for a cycle, or was that not clear - possibly igniting at the wrong time? The simplest interpretation of "bad plug" or "bad lead" would be one that doesn't consistently spark, but Chris brought up the question of whether there might be cross issues with the leads, which would imply mis-timing. Was there anything about the conditions of the test that would have made it make sense that no stutters occurred on that flight? I don't think I understand what might have been happening, but it's great that it seems to be addressed! Looking forward to what you share from your trip to the Arctic!

Intermittent is so frustrating, especially if they vanish without an obvious reason.

My grandfather was a production manager at Metropolitan Vickers, Trafford Park Manchester UK. He oversaw the manufacture of the airframes for the Lancaster Bomber.

LOL

I fully agree I wouldn't tolerate any stuttering. 😊 Just like a car on the ground, we ( people in general) have to stay on top of our machines.

Nice video and troubleshooting, Glen. I also have the ElectroAir on my DA40. One question: when you uploaded the engine data to Savvy from the morning's stumble run, did those graphs show anything? Suggestion: if you do see the stumbles again, maybe go to real mag for a while, then EIS for a while (recording your engine data)... that may help further isolate the phenomena. Keep up the great postings! Thanks. Wayne (DA40 KSBA)

Chk. fuel for water etc. What's a little cold big bears

I enjoy your videos, especially the troubleshooting and maintenance vids. Like the previous comment... intermittent problems are the worst!

Great start to troubleshooting, I work automotive and intermittent issue are such a pain with new cars. Starting with basic stuff like you did in most cases solves the issue even though you may not see the root cause during the diagnosis. A white leaner plug compared to the rest is always a bit of a warning sign, you can eliminate a carburetor issue as that's the common feed for fuel for all six but since they all have individual runners you would think that a leak in the intake on that cylinder was the cause, but that would be all the time and not intermittent. That only leave the ignition system. hope its all fixed up :)

Hey Glen i hate to hijack your comment stream. In the July issue of Sport Aviation magazine there is an article about the history of the RCAF. Being a proud canadian i thought you would like to know about it. Very interesting and worth reading.

Oh, that's frustrating. Intermittent faults are a pain in the neck.

Well done Glen and good info on the electroair! What change in stol and cruise speeds are you experiencing with the sportsman installation?? Would you do it again? Contemplating this myself! Thanks

the SOUND of the Lancaster - nothing like it. Four Merlins, such an iconic sound (as is the P&W R2800). That low pass starting at 4:53, the sound is identical to the Lancs on their passes in "The Dambusters"

Nice to see this as I was there when the first one lande at this air port and I still remember as if it was yesterday

During World War II, Goderich Airport hosted No. 12 Elementary Flying Training School (EFTS) for the British Commonwealth Air Training Plan, providing initial pilot training for aircrews using the Fleet Finch. Like most of the other EFTS, this school was run by a civilian flying club, in this case, the school was operated by the Kitchener-Waterloo and the County of Huron Flying Clubs. No. 12 EFTS opened on October 14, 1940, and closed on July 14, 1944. I was there with the Lanc flew in for mounting as a static display.

The Lancaster never saw WWII service. It was search and rescue only.

5:10 This, Americans, is what more than half of Canada looks like 🤌

That lanc at full tilt! You guys are great too.

Haha. 18:26 i recognized the village next to where i live😂. Hiway 20 at Saint Apollinaire. Im like 10 mins from there

Come visit us in Québec city! You are more than welcome!
