Exploded views of a transmitter is not something I've ever come across- only diagrams of the outside with labels for all the buttons & switches to explain what they do etc.

An exploded view of an actual model is extremely easy to find however, though buying a couple rcs to dismantle might be a tad much.

I think stick vs pistol cheapo radios is the best route- different enough in how they look ( trigger throttle & steering knob vs a pair of gimbles for throttle & steering ), but identical in how they achieve the end result of controlling the model.

CDT AS level sounds kinda hard- I did an A level in it and never had to compare 2 products, was more to do with a joint project, a case study, then the final project which took a whole year....
