I'm completely happy with it. No twist and has held up very well with abuse. Along with putting the wing on upside down, I couldn't ask for more. With the wing reversed it dosn't flex any more than other foamies I've had. Now an outside loop.......thats a different story. I fly indoors and the bottom line there is wing area. I've looked around and this is one of the few to offer just a hair under 375 sq. in. with this wing span. I think with the side stiffeners it brought it up to about 400 sq. in. Still have the stock landing gear with original glue job and no problem with the motor mounting stick. Joe
