I wasn't commenting on the pictorial instructions, which look to be pretty good. I was commenting on his (the website author, not the poster) reason for taking the unit out.

I'm just guessing, but I don't think it's legal for your blades to park within the field of view. But more to the point, it's about the silliest thing I've ever seen.

Why do they race with the blade parked up? To keep it from getting stuck with debris or something?
