The Sig Super Chipmunk is a control liner. I have seen one of these converted to RC but you will be in for some challenges. Though I have not built this plane, I used to do CL. Many CL planes (especial stunt) are designed specifically for control line. This means that the inside wing (this would be flying counter clockwise) may be 1/2" or so longer. Additionally, the fuselage will probably be narrow as compared to the actual real aircraft. CL wing position tends to be more centered on the plane lengthwise this is because the plane is designed to only go up and down while keeping the lines taught.

Good luck and let us know how your mods come along.
