Complexity:

The Super Cheeter builds quickly, usually under 5 hours.  It flies fairly fast, yet is light enough for low lift days.  It is NOT a trainer, so don't even THINK about using it as a trainer unless you are adventurous or already have an aptitude for things of this nature.

Since it has only 2 channels, it is very low complexity in terms of radio installation.  Simply install the Elevator servo, attach it to the Elevator, mount the Aileron servo in the top of the wing and connect it to the Aileron horns, velcro the battery and receiver to the fuse and route the Antenna.  Done.
