The Dr 1 is one tough plane. Flying in it or against it, I find it can take a lot of punishment from bullets and high speed manuvers.

Curious, I decided to undertake a feat I would normally never attempt in any other plane… I decided to take the Dr.1 up to high altitude, nose dive straight for the ground, and see if I can pull it out in one piece!

So here I am at 4k, ready for my dive!

As you can see, it's a long way down. But there's no turning back now. I'm going straight down and I'm pulling up before I hit that town!

Here you can see my angle of attack. A nice 90 degree angle, a broken engine, wet trousers, and a look of pure fear on my face.

The town is approaching fast. Will he make it? And did he remember to write his mother?

Huray! I slowly pull out of the dive at about half a kilometer. Here I am, safe and sound, gliding over the town with a broken engine and a wet pair of trousers, but the plane came out in one piece. If only I had a place to land…

Jokes aside, I've done this trial numerous times. The only thing I tend to break are of (obviously) my engine, and sometimes my controls: aelerons and elevator. If I take a less severe angle of attack, say 80-70 degrees, I can sometimes pick up enough speed to tear off a wing or three, although I have gone far in the red (300-320kph) without completely tearing the plane to shreds.

Obviously if I yank right up on the stick, the wings will pop off like confetti, but the plane can survive a high speed dive with little problem. I'm not sure if it's a drag, weight, or wing strength issue, but it doesn't seem quite right.

Once your engine dies you probably only hit terminal velocity which probably isnt fast enough to crack up the plane, I tihnk the DR1 was one of the first to use a semi steel construction right? The pull out is another matter, I dont know the G loading of your pull out :D haha he said…oops wrong place.

Full Ammo and fuel loadout for the dive. It was a gradual pull out. If you yank up on the stick, yes, the wings pop off.

If you do an idle/engine off dive, your airplane will (for biplanes) slow down in a dive compared to straight and level power on flight. 3 wings is a lot of drag afterall…
