Theoretically yes, but you would have to be lucky enough for the dragons to cross paths at exactly the right time.... and like another commenter already said, the Light Dragon flies significantly higher than the others, so if you plan to hop from one dragon to the other, you'd need to ride the Light Dragon first, not the other way around.
PS: you can park a hoverbike on the Light Dragon's head, which makes the trip from one dragon to the other a lot easier. It doesn't work that well the other way around, as the other 3 are taking a nosedive when going underground - you'd fall off, along with the bike.
What do you do once they go back to the surface? Does it also work if you park the vehicle in front of their horns, or do you have to stand on their face and use Ultrahand to hover the device?
Yeah, it does. You just have to look for the flattest surface you can and flip your hoverbike upside down because it has the most friction that way. Maybe itās the handlebars?
I fell off a few times, got flash-frozen by Naydra because I forgot to upgrade the Snowquill Set for immunity, but with a bit of fine tuning, it worked at least once ^^ I'm just a bit too clumsy to relieably pull it off every time, but it defo does work as advertised.
Maybe I'm missing something here (are dragons a no-build zone?) but my knee-jerk response was to just auto build another bike rather than rig it so it doesn't fall.
They get fairly close to each other at times. Iāve seen Light get a short glide of Farosh and Naydra before. I donāt really know how lucky I am but Iāve seen it about a dozen times and I donāt even hunt dragons; I just fly up to dragons the moment I happen to see them.
