Your next question and much more difficult one is ---how is the quliaty of the leading ARFs , you will see that oregin of supply has less to do with quality then the standards set by the company making the demands . Its all about the bottom line vs the assumed retail value vs demand .
Some ARfs will sell for $269 list and will really deliver , others for $400 and deliver less and others for $600 to $700 and offer the total package of scale and range from above average quality to way above .
However you will see that quality when not effecting the actual flight value will vary by the individual modelers choice .
