Hobby-Lobby How-to page
Sounds like they are trying to get people to buy one of their easy to learn beginner trainer planes. The ones that are very easy to fly as they say. I am sure they are easy to fly but it would not hurt at all to have an instructor present at the time of the first launch.
Who knows if the wings are warped or if the trims are off a little. This would more than likely be hard for a beginner to correct the very first time flying.
I don't think this is good advice to give a beginner especially if they are looking to get in the hobby for a long time. Maybe for someone looking for a plane to play with and if it crashes no biggie.
