Charlie, it's like a "Safe Boater's Test" for RC Pilots. Know the club rules, how to start an engine,demonstrate control of the plane (turns. figure 8, level flight, etc), be able to do a proper landing and take off. Disqualified if you are wrong side of the runway on take-off or flying in the restricted area.

Congrats. Have no idea what the WRCC Wings Test might be, but glad you got through it and can fly solo. Just be sure to have a buddy at the field when you do. ;-)
