I can say this, One month ago I had my hardest landing with a plane without it being totaled. Our field marked the runway with stakes so that it could be paved. I didn't see the stakes, I hit it on landing which flipped my plane over and spiked the rudder destroying the top half. The left landing gear was still straight, the right was bent 33% (yep, I measeured it.) Their was a small 2-3 inch crack but no breaks and no other damage. the plane is now back together and I will fly it over the holidays.

You CANNOT ask more of a plane or its builder than that. The plane is sturdy, flies great, and if this is an indication of Great Plane's ARF quality then I am sold. I have measure the thrust of both of my planes and they are both around 1 degree. I just use two yard sticks and measure the difference and use trig to solve the angle.
