Lycoming-powered Diamond DA42 Demo

nice aircraft!!

[RADIOACTIVEBUNY]

That thing is sexy.

[technofreak]

why'd they get rid of FADEC...seems like a step backward to me

[last1in]

@technofreak

As a trainer/ first owner aircraft, it seems like getting rid of the FADEC was a good idea.

What is the name of the song in the background at the beginning and end of the video?

[bishop102]

Does the diesel engine make engine startup more difficult in a colder climate.

[nicoacuorg]

@sksakm14 20" could be right, but I think it's much less than 70% power, rather closer to 55%. I'll check, though.

[100LL81]

Did he say 10.8 GPH per side?? He was talking about climb rates just before, was the 10.8 in a climb. I am assuming.

[YeaSon2008]

@100LL81 I am a student at ERAU and have trained on the DA42L for the past sem. At 55% pwr, the fuel flow is 7 gph/side (higher than the theilerts but still ok). At 75%, it is in fact 10.8/side tho. T/O power fuel flows are at 12/side! To remedy the high fuel flows, the DA42L's at ERAU have auxiliary tanks built into the engine nacelles, holding 13.7 gal total per tank. For W&B issues (since the lycomings are so much lighter), you will need to employ ballast weights in the nose baggage as well!

[nicoacuorg]

Where can one see your video. I have fond memories of a friend who owned a Mooney with the hand operated gear lever. Fastest retraction in the sky.

[nicoacuorg]

You are right it has 320's not 360's. I was mistaken and already apologized to Paul for the mistake.

[av8rdav]

When I got my multi-engine rating, I can assure this reporter I didn't learn to identify the dead engine and secure it by rote.

[nicoacuorg]

Just a note on the fuel burn - it cannot be 10.8 gph per side. I had a Twin Comanche, same engines, and burned 11 gph both engines for years. That must've been 10.8 gals total.

[Nemesisnxt]

Wow, your O-360s only burned 5.5 gph each? Impressive considering my O-200 burns 4.5gph at cruise. Lycoming published specs say that best comsumption is .43 lb/Hp-hr which translates to approx 11.5 gph. I'm very sure they are talking about 10.8gph a side at a high power cruise.

[Nemesisnxt]

oops, bad math, I figured it at Jet-A weight. Habbit. Its actually 12.85gph for avgas @ 6.02lbs.

[nicoacuorg]

The Twin Comanche has O-320's not 360's, which accounts for the lower fuel flow. My calculations were not by guage or fuel flow meter, which was not really reliable, but I calculated total time flown and total gals to fill up. That gave me an overall fule burn rate. One more thing: we used imperial gallons, which is 4.5 litres and not US gals, which is 3.85 litres, so I will show a much lower gph.

[nicoacuorg]

At about 10K feet the MP is under 20" which is under 55% power. I still clocked 160kts depending on winds aloft. At that power setting it's no wonder that my figures differ from a 75% setting at low altitudes.

[bill3rdshift]

How much does it weight?

[flyyves]

It remains one of the most ugly planes in the world. Yikes.

[darrenvox]

nice plane ive never been in that factory...good to see

[Billy982810]

Not to mention the smell. Who want a plane that smells like a bulldozer.

[mrhaydon]

looks like a really nice aircraft, not too keen on the whole burning twice the amount of fuel though
