As a pilot myself, and I love your videos and hate correcting engine gods like yourself... when the plane is flying,both mags are running. The only time that we switch A to B mags is on run up to make sure they are working. You typically see a 100 to 300 rpm drop while switching from A to B but while flying both mags are running.

As an aviation mechanic, I’ll add some context to the aviators comments, both mags are running at the same time on aircraft engines i.e. Lycoming/ Continentals mainly for performance. Aircraft engines have large bores relatively speaking, and the spark plugs are mounted more or less opposite each other and the idea is with the two spark plugs per cylinder the fuel mixture will ignite on both sides of the cylinder and meet in the middle giving an even burn, thus more performance, which is why with one mag off you will get the rpm drop and a rougher running engine, the secondary benefit is the redundancy of two ignition systems. However, what Steve is working on is for experimental aircraft, with an automotive engine, and the extra spark plug is there only as a backup.

Took my private pilot in 1991. Part of startup checklist pre taxi is a mag check. Increase rpm, switch to A, switch to B, return to Both. The idea is to NEVER lose a cylinder from firing at all.

When I built Rolls Griffons for an Unlimited Hydo team, it had dual Mags in one housing. We also advanced one 2* more than the other. Must have worked. We made over 5,000 HP at 4209 rom with sequential 14" centrifugal compressors making 130 in/hg approx 65 psi, and we had 150 lbs of nitrous for a single 900 HP hit when accelerating. (Starting run, exit from a turn, and finish line, if needed.). At the push of the button, the boat would walk 6feet sideways from the 15.5" SS prop. ($10k each back in 1985😳). Id love to see a SMXXX V12 WITH 2,300 CID. With modern turbos fuel injection and alcohol, I figure 7500-8,500 HP would be easy today. I had develooed a system back in 1989/90 with turbos (4) and efi we calculated 7200 hp at 3200 rpm. (Griffon-2,240 cid 4V/cyl. OHC) for another team. They ended up going turbine. Much cheaper and a lot lighter, they look cool, but sound crappy, says everyone. What do you say, Steve, shall I start lining up sponsors? Maybe just use two SMX's would work, but eextreme low rpm torque is needed AND reliability, nothing hammers an engine like 235+ mph with only half the prop in the water.

As a pilot, I can tell you that on airplanes there are two independent magnetos and spark plugs firing for each cylinder continuously. The only time only one ignition system is running is during ground run up. The system is tested by setting a rpm and switching from both to #1 system, then both to #2 system. Each time you go to only 1 mag, the rpm should drop by a specific amount. That’s how you know both systems are working.

John Williams, the owner of Titan Aircraft, recently had a fatal crash in one of his T51 Mustangs from a prop hub failure. They also use v8 engines, which keep the cost of the 3/4 scale planes lower, but come with the added risk of hub reduction systems failing. Since props can't run over ~2,600 rpm, the engine has to be geared down to achieve torque and hp peaks, which are above the max prop speed.

@recoilrob324Ай бұрын
I was with Stewart 51 in the beginning and was the 'engine guy'....and lots of people wanted dual plugs for 'redundancy'. My thoughts were that the single plug was ideally placed and rarely failed so unlike the huge bore hemi's used in most other aircraft engines...dual plugs weren't needed or desired in a Big Block Chevy. You CAN run dual ignition systems so you have redundancy while still using the single plug just like they do in NASCAR and IMHO is the better way to do it. It's funny that the S-51 design NEEDS an iron block and heads for proper Weight and Balance...but everyone wanted to use aluminum blocks because they're lighter and somehow they thought this was 'better'. If ballast is needed it's WAY more effective back in the tail to correct nose heavy because the arm is so much longer. If your light in the nose you have to add a LOT more weight which totally defeats the purpose of the expensive aluminum engines. The original Merlin's are HEAVY beasts of an engine and the S-51 mount plenty strong enough to hold the iron Big Block as it was stress analyzed by an old Grumman engineer who wrote the book and we worked together to build them able to handle 9G's with the gearbox and Hartzell 4 blade prop hanging on it. ALL aircraft engines today run dual plugs with dual magnetos for speedier flame propagation and the redundancy you get is just a side benefit. When doing your pre-flight run-up you always do a 'mag check' by switching one mag off then the other and you watch for a known rpm drop and rough running when only on one. That way you know they're working properly and while the engine does run on only one mag...it doesn't run properly and if you have a mag failure you need to get on the ground ASAP.

“Fastest 4 Wheel Drive” is an assertion that can be made on KZbin without any real verification standards.. might as well say, he’s the most successful racer in the world.

1:35 part of the problem is you just said aircraft or airplane. That scares people. That triples the price , or causes alot of refusals to work on it. My dads 46 Luscombe uses a Model A ford fuel gauge. Price out one for a Model A ,and then price one out for a Luscombe. Pretty much the same part, but the Luscombe one costs triple, because it has the "FAA blessing". Dont get busted with a Ford one! Aircraft liability crap is absolutely insane sometimes.

Pricing in aviation STARTS by moving the decimal point over one... then goes up by supply, demand and what people / companies are willing to pay to get that A/C out of AOG status. (Aircraft On Ground) for those not familiar.

They run the T-51 through a 2:1 gear reduction box. They need low end torque more than hp. Great video Steve. Music rocks.

A Titan T-51 crashed on July 21 2024 due to a prop hub failure. Blancolirio covered this using the preliminary NTSB report.

That dual spark set-up could also be used for marine applications...(but you already know that).
