Blew a hole in the crankcase. Walked away just fine. He had practice, in 2006.

For those of you without FB, two picture preview:

I thought these engines were loafing along so much the power could be turned way up with no detrimental effects? :rolleyes:

Keep on hitting more boost and eventually, the engine will care. Glad he walked away.

"You can't get hurt in the dirt"

but seriously, my first thought was that he did a good job of picking a good field and keeping the wings parallel to the surface. touchdown speed cannot be slow in that beast and it could've been a lot worse
 
****.

Nice job on putting it down & walking away. Might even live to fly again.
 
When you are on the ragged edge you will get bit,

Nice landing!
 
Man, the things folks will do to get some crawfish.... pleased the pilot is okay!
 
Glad he walked away, sad to see the plane in that condition though. Then again, says a lot for the NXT that it still looks wicked fast in the dirt.

Odd. His page and post are public (world icon). I don't have him as a friend, and I just checked and the page is still there.

Worked for me too, so on a hunch I logged out and was able to recreate the error. Seems you don't need to be his friend, but you DO need to be a member of FB and logged in when you click the link.
 
Glad to hear he's ok.

Hmm... that's an interesting looking engine he's got. Bonus points for who can figure out what's different about that vs. a normal IO-720.
 
I know, teach, I know!

Most of them are in planes that are parked at the airport rather than gear-up in the middle of a bean field.

Wayne, your keen sense of the obvious never ceases to amaze me.

And we have a winner! So theoretically, that means it should make less than 400 HP. But they aren't stock heads...

Duke?

I have never heard of a 720.

The 720 wasn't in the Duke, that was the TIO-541, 6-cylinder. That said, I think that a turbo 720 would've been a perfect engine for the Duke and P-Navajo. Given them better performance on probably equal weight.

The IO-720 was an 8-cylinder derivative. Basically an IO-540 with 2 more cylinders, it only had the high-flow, high-power cylinders on it from the factory. Its most notable factory application was the Comanche 400.

I;ve heard is described a few times as an IO-540 with two more cylinders. Why wouldn't it be described as a doubled-up Lycoming IO-360?

Either one is accurate, since a 540 is basically a 360 with two more cylinders. :)

Now it leaves me wondering about the why, I get that they aren't stock cylinders but it still seems odd to have gone to the cylinder off a lower powered engine.

Parallel valve heads probably save him 50-70 lbs. And with the "these ain't stock heads" modifications, I'd bet he's making well over 400 HP.

Also notice that it's a narrow deck engine. Narrow decks weigh less, too. But I don't think the 720 was produced in wide deck.
