Chord... I didn't measure. Span of a stock Kadet Sr is 78 inches. I stretched mine to 83. (and it has flaps and ailerons)

The normal proceedure when flying a R/E/T aircraft is to put primary turning control (rudder) on the right stick. This is how the traditional Mode 1 got started... when ailerons were added, they were assigned to the left stick because the early R/C pilots were used to the rudder on the right, and the ailerons were considered a secondary turning control. The Mode 2 setup developed for compliance with the control yoke in full scale aircraft.
