Hi Tim, I got your e-mail. I have my stinger covered and all hinges glued in. The control surfaces work well with good travel. I am going to use button head screws to fasten the turtle deck so I can remove it to get to the rear area if I need to. I have the servos installed and control rods connected. All I have left is engine installation, cowel, and smoke and radio to be installed in position to balance the plane in the C.G. range. Wayne
