When hovering in flight mode vertical prop extended, the engine stalls and the props bend slightly as it drops probabaly 5 to 10 yards give or take, the engine will kick in again and pulls you back up. As far as I can tell this animation only occurs when idle not during ground or flight movement. If you are hovering on the ground the vertical prop is retracted and it will not touch down in hover mode unless it stalls out, when it does it slams down and you try to crank the engine twice and you're hovering again. I can't confirm that it takes 350 to make, but it only seems logical that it becomes available at 350 to make and fly as the epic version does at 375. The rare version listed here does not have any frills like paint or the hula girl on the dash. Comment by darkfanboyNote, the mount with the flames on it is actually the epic version.
