Guys, you are making the four stroke sound like you need to be a faa certified mechanic to even think about taking it out of the box.
To set up a 2 stroke.
You position it on the motor mounts, drill and screw it to the motor mounts. run the throttle linkage to the throtle servo. Hook a fuel line from the carb to the klunk of the tank. Run a fuel line from the muffler to the tank vent. Hook up a glow ignighter, Start the engine. Tune the high speed needle. Tune the idle mix. Go back and tune them again. fly the plane.

You left off the break in and setup. Valve adjustment, differances in tuning (hard to tune a 4 stroke by ear, and other. That said I would put a cheap 2 stroke on a trainer, if nothing else than the fact it costs less to lose in a crash. Keep the four stroke for your future low wing trainer. Nothing wrong with having an older trainer to warm up with before flying the low wing craft.
