No it has no former or ladder frame. I had just rolled out of the bunt manuever wind was about fifteen MPH blowing out. I think the combination of right rudder and up elevator during the roll out provided the stress that resulted in initiating the failure but the actual failure occured in atraight flight when I powered up for the double embelman at the center of the box. This airplane has been flown on a regular basis in four or more contests over a period of eight month's including many practice flights.
I think that the seam in the vertical fin opened up on the left side first due to the absence of seam tape required to strengthen the joint allowing wind forces to enter the opening which initiated the failure. The rudder pull-pull is perfect, absolutely no slop, elevators the same no slop.elevator push rods are supported by a ladder frame which is secured to the top of the stab tube in the rear and several cross members in the fuselage. all of these are still in place leading me to believe that the failure was not a hormonic vibration or flutter but a side force which caused the fuselage to oil can to the left as indicated by the compression ripples on that side versus tension cracks on the right side again leading me to believe that failures are only experianced when the exact forces are combined to reach the critical design limits of the airframe.
I was as in other cases able to land the airplane without further damage and would like to locate someone who has successfully repaired one of these to find out if repairs are possible and how they did it.
Also I would like to hear feed back from those who were able to get a response from Composite-ARF
They state that there are over 350 sold with a few failures, but it looks like there are more than a few, I wonder how many? Seems to me that they should do something to help those who suffered the loss that was due to their inadequate design. I guess we will see what they are made of before this is over.

This is a sweet flying design in every respect and I would like to be able to fix it but havent figured out where or how to start.
