health kit? you mean first aid kit? though i know about the health kit [still have it , and im 13 ] though back on topic
i dont think RTF or ARF will take over, maybe for the people just starting the hobby[me though been saving for 5 years... maybe longer] the main concern of getting a kit is beginners are really afraid of screwing up [or just start building the thing on their bed...*cough* and lose a piece] well best of luck, though me and my friends started to build a kit [3 years ago] it was about 5[the plane kit] years old [now 8] and the instructions were lost so we decided just to blindly make it , everything *looked*[and actually was...] good until he made the wing...... he glued the wing into one piece and it wasn't an airfoil though i plane to get building that thing again once i get more money [maybe in 5 years...........]
though preferably i would get a kit, i just love making things putting things together [been working with wood for a long time .. (7 years believe it or not) as for electronics.. my knowledge is really high up there im so proud of it (maybe to braggy about it..)]
well GL and hopefully something does not break......
