Step 1 : Frequency control (don't turn on when somebody else is flying on your channel.)
Step 2 : Safety concerns - radio range check, linkages check, hinges secure, control surfaces move the correct direction, all connections secure, prop secure, no fuel leaks, wheel collars tight, etc.
Step 3 : Learn to fly straight & level, learn to make turns, learn to control the plane when it's coming at you, and learn a little about throttle management and rudder use.
Step 4 : Learn to land.
Step 5 : Learn to take off.

Of course, opinions may vary, but by taking my students through this process, I find they get to fly right away, and their initial investment is preserved - usually long beyond the instruction period.

Best wishes,
