Coming from New Zealand, we're the land of the mighty Fletcher FU-24 aerial "farm dump truck"! Now replaced commonly by the Cresco 600 with a PT6 turbine on the same airframes. I have some memories from my childhood of seeing some Fletchers roaring around the countryside, "down in the dirt" when on holiday around the South Island of NZ. The big 720 "growls" its way into the sky. With loving the sound of V8 Supercar racing, these big Lycomings sound just as good, with the added long blade supersonic prop tips cutting the air like a buzz saw! Thank you for a great compilation of new & old video of an enormous and now very rare engine!
I live in Idaho & have a low time 720 running on a stand. I bought a Piper Brave at a local auction for $600 that was crushed in a barn collapse from snow load.
The Comanche needs "augmentors" like the Queen Air. That really makes a unique sound. Great video--I had forgotten there were a number of applications besides the Comanche and Brave. Thanks! (thought you had a video on Geared Lycomings too? )
Ow Boy I just Love that Sound of that 8 cylinder Beast, incredible !! I am in South America in the jungle and I was thinking of a io 720 in a Cessna 206 ?? But then I am a Poor Man !! ❤❤😅😅 Thanks for the video clip love it !!😊😊
We operated one on paper runs. A pig to start hot in summer……..the starter motor had a hard life and sometimes a jump start was needed through the back hatch.
I can’t help but somehow all Lycs have that agricultural sound. For me at least an old 180 or even better 310 with a 470 is the best sounding O engined aircraft.
@@aircraftadventures-vids It’s a two-seater Canard ultralight aircraft introduced in 1982, it became popular within the USA, even Chuck Yeager himself flew it. But where it hit the top number of units was Argentina, most Falcons were imported to Argentina between the 1990s, and it became a big success within Argentine ultralight aviation. As of 2023 there are a few examples airworthy. It’s equipped with a Rotax 582 engine, and has a top speed of 75 mph, and can fly for about 2 full hours. Many Argentine student pilots loved it.
Ah ok, an ultralight. I actually do remember that one, yes. I'm thinking of doing a compilation of antique ultralights, which I find interesting. Tx for the suggestion. @@Sylver9898
Great old engine when properly operated and maintained; kind of cranky to start when hot, but it gets the job done; you would have to be an Arab to afford the fuel burn and maintenance, and on takeoff the people 5 miles away know your going flying😀
You have no idea how much I enjoyed that sound!
Glad you enjoyed it! It's certainly one of my favorite engines (one of...as there's many, lol)
Me too, very impressive!
I love the sound of those 720s. The sound just takes over the whole sky when they fly over.
Beechcraft Queen Air is one brute piston of a twin !

Flew the 680fl aero commander with ‘mr rpm’ turbo io720’s . An absolute animal for a piston twin.
I love my 720 legacy! Definitely hard to beat.
What a distinct sound signature ! Wonderful
Best and perfect sound !!!
Yes indeed!!
Sounds almost as good as a radial! Very nice.
Lycoming engines are better than any music. My dad flew a twin bonanza and a queen air. These sounds remind me of him.

That would make a perfect match
Wow what a plane. It used to be called the 400 Shark nose.

Now thats what I’m talking about the lancair if you don’t have a PT6 then it’s the 720.

Have you heard of the Falcon XP?
Have not, what’s that?

I wonder how Lycoming IO-720 sounds without propeller...
The sound of an explosion
COOL
What hp is the 720
400hp
Those aft two cylinders must have cooling issues.
I think they did. That's what I heard about the 720 powered Agricultural aircraft
Wonder why they never made a turbocharged version?
They did or rather there was a conversion for the aero comander
Any Comanche 400 or brine Excalibur out there in need of a home? I would love to restore o e back to airworthy conditions ❤🎉
Saved the best for last.
Nah I prefer the 0-100 continental myself or even the 0-200
We'll all sleep better knowing that.
@@karldunnegan2689 I'm so happy for all those that can sleep better knowing that . I guess I did a good deed.
