A person that has put a few planes together can assemble an ARF plane about 60" in 2 to 8 hours depending on what plane it is and who makes it.
Not me. I finished up a Cox Giles 202 in perhaps 15 hours this year, and just spent 6 hours on a Kyosho Flip. I expect the Flip to take me another 10 hours or so. Heck, it took me almost two hours just to get the covering the way I like it.
