How long you’ll need to finish a plane depends upon a wide range of factors, not the least of which is how often you actually work on it. Other factors include the level of detail and finishing work you plan on, and what kind of building skills you bring to the table. You don’t need any prior experience to build a Van’s, but it certainly makes things go easier. First-timers should plan on spending several hundred, or even thousand, hours building their airplane. So-called «repeat offenders» who have built two, three or even more airplanes can crank one out much faster.
