You could have mentioned that it was a model...:D

Can't understand the language, but I do speak fluent turbine, so I had no problems with that part.....:D

Hello Guys.

I was the supervisor on this project and all I can say is that we are really pissed. My friend Michael Dines from Copenhagen has spent a lot of time and money on this project and had been looking forward to flying his Concorde at the recent Jetmetting in Sønderborg/Denmark. The instructions stated a CG that obviously wasn't correct. Michael even spoke directly with mr. Michel af last weeks fair in Dortmund/Germany, where mr. Michel confirmed that the CG was correct between 80-120 mm ahead of the main gear. Michael set his CG at 90 mm. As you can see from the video, that thing was tail heavy as h e l l. Michael had no chance to rescue the plane from total disaster.

See the [link=http://www.tvsyd.dk/page/13?article_id=16157#]VIDEO[/link] in this article.

See the intire build tread [link=http://www.rc-unionen.dk/nytforum/topic.asp?TOPIC_ID=10594]HERE[/link] It's in Danish, but there are a lot of pictures of the build.

Thanks for the links Stig.. It did look spectacular Prior to its mishap though....Nice to see some Civil Aviation Model aircraft..

RE: Concorde Crash...
 

I suggest an electric ballast next time with seperate TX/RX and pilot to adjust on callouts.

RE: Concorde Crash...
 

Stig,

It looks like it might be repairable, I hope your friend trys. From the videos of Michel's that are out ther it seems as if it can fly very well.

I wonder if might be one of those planes where it takes a lot of weight to move the CG. I.e., if you do a second attempt, you might check and see how much weight it actually takes to move the CG to the forward point at 120mm. You might find that it takes a really significant amount of weight to move the CG foward even a little bit. That, combined with the fact that perhaps, even though he listed it as an option, Michel may never have flown the plane with the CG as far back as he states, may have led to the plane flying so tail heavy even though the CG was within "specs."

Its a bummer, but I do hope it flys again!

Sorry about the crash, I and I know how hard is to be the supervisor of a failed project, (don´t ask me how I know this, lol).. but you guys should keep in mind that pushing the limits of our sport, like building a B-52 or a Concorde could lead to a not so good result as expected... the solution is quickly understand what went wrong and start again. Like Bob cited above, the plane seems very repairable...good luck in the next try.

So sorry to hear about and see your crash. These things do happen and in this hobby it is just a case of time before they will happen to all of our models. It just hurts more when it is a favorite one.
I too fly a Concorde from Peter Michel and I have had no trouble with the CG. In fact Peter and a gentleman named Michel Bauer built my model and since I took delivery I have removed at least 24 oz's of lead from the nose. I am amazed that yours should be so tail heavy as mine has two heavy AMT Mercury turbines in the back and no extra nose weight to balance. In fact I use Lipo's (Not heavy nicads) to balance mine. But having said this my total weight is 19kg. I think I saw somewhere on your thread a weight of 24 or 25kg. Was this with fuel???
Anyway I am sure you will rebuild this model, and I am sure it will look just as marvelous again. I am just considering if I should take the dust of mine and fly it again this weekend after a long winter break, or wait until I come back to the uk in a few weeks time. I have attached a few images to inspire your repair.
Regards Al

Sorry 'bout the crash, I know that hurts. However, in the video posted in the link above, you can also see there is also heavy flutter and oscilation on the right aileron and outer wing tip. It happens just after the person is heard to yell out something (my no speaky Danish) :D so I am not sure what he is saying. It happens just before the nose pitches down and then again as it pitches up. Not saying it had anything to do with the crash just something to maybe look into.

RE: Concorde Crash...
 

Hmmm..

I saw that Pat ...but put it down to the video quality on full screen ..I'll have another look i think.

RE: Concorde Crash...
 

That 'flutter' looks like a comination of high digital compression of the video and hot exhaust gasses to me...

So sorry about your loss, Michael[&o]

RE: Concorde Crash...
 

Thanks for this information, Patrick. I'll pass it on to Michael, and he can look into it. But I think he was just "stirring the pot". [sm=drowning.gif]

Ståle: Your bellmouth is going out next week. Kurt Hevang had one in his shop, and he will send it directly to you;)

RE: Concorde Crash...
 

Thanks so much, Stig!
Please also thank Kurt for me.

You guys are saving angels!:)

RE: Concorde Crash...
 

After reading all of this I am wondering if this plane has different fuel tank placement than the one which flew well?!?

RE: Concorde Crash...
 

Yes, I was thinking the same thing. Could make a huge difference.
