Hey Sandy , That is a good idea you have there , I will see how the holes across from each screw works , if not will try that idea .
Did you secure both ends of the wing struts , or just the end that screws to underside of wing ? I wanted to do aerobatics , so I made a brkt on the undercarriage to also support that end , else 1 end is free . How could you bang up 2 of the SR9 ? If it was an Extra or such maybe . AL
