OOPS!

[Mark Hunt]

I was there, standing next to the guy taking the 2nd (good) video.  The amazing part to me was that the pilot and spotter stayed very calm.  Being there watching, (seemed like slow motion) it was also obvious that the pilot induced high roll rate and idle, which created enough drag, coupling, etc., that it got the nose pointed downward before continuing on its course behind the flightline.  Many nice compliments were given to the pilot after the crash for his skill in preventing a much worse scenario.

  This crash occurred back in May 2003, I recall reading about it back then. I was able to find the following thread regarding the incident on RCUniverse. http://www.rcuniverse.com/forum/m_745606/mpage_1/key_imac%255Fcrash%252Cwmv/anchor/tm.htm#745606

  There was much speculation regarding the failure and discussion of whether or not FiberClassics had produced a defective product. In response the pilot, Niklas Nyroth, posted the following message:

  Hello, 

  Thanks for the comments and kind words. 

  Lets just make a couple of things very clear. 

  This airplane was a pre-production, experimental one of a kind, 
  In other words weight savings was incorporated that does not exist in regular production planes. 

  The airplane was involved in a very rough trailer ride last summer where the tail section was subject to some massive forces, i wasnt able to detect any visual damage but it is not impossible that it was the initiating factor. 

  I think that with over 300 produced and only one known inflight failure like this, there is no reason to worry. 

  I for sure will order a replacement sister for this one and i am not worried for the structural strenght of it. 

  This is certainly not a manufacturer problem. 
  Any structure can and will, fail if not handled right. 

  I have flown full composite air planes for over 10 years, i fly and design full composite UAV's as a living and i will continue doing so because that is to me the ultimate in strenght, weight and all over performance. 

  Hope too see you all soon with my next full composite airplane.

    Eric,
    Amazing video! Was that a FiberClassics rohacel laminate plane?  Why did it fail?
