There is something about speed... And about "dragon problems" ;)

Why ruin the "magic" with real life physics? B-)

Toothless actually obeys lots of real life flight mechanics. He's based of of many different birds.

Oh for sure, I meant as in when people decide to pick at the smallest of errors and turn it into a big thing. I just want to enjoy things for what they are and not what they should be. :D

mystery dragon, pic drawn by night fury fire. Thank you :)

I think he was really fast before he met hiccup. And after hiccup started riding him he would get slower. But I also think after a while his wings would get stronger to adjust for hiccups weight. And then he would gain has speed back.
Dragons, need I say more.

Hiccup, chief of berc, dragon master.
Toothless, alpha dragon.
You and me bud we can do this, as one.
It's just a zipple misunderstanding
I like a pit, but I love a boar pit.

Here is a approxiamte calculation about Toothless' maximum speed in a free fall:

v=sqrt((2xmxg)/(pxAxC))

m - mass (I used 130kg for it, if his is higher he will be faster)
g - acceleration (9.81 m/s^2)
p - density of the medium (air at level 0: 1.2041 kg/m^3)
A - area of the falling axis (according from the size of a 3D model it is around 0.8 m^2)
C - drag coefficient (without his wings he have a nearly ideal streamline shape (0.02), I used 0.06, that's a bit lower than an airplane)

v=sqrt((2x130x9.81)/(1.2041x0.8x0.06))

v=210.07 m/s = 756,26 km/h = 470 mph


Maby no sonic speed, but still very very fast.
In a high of 1000m he is around 10% faster.

No, I'm serious....stop it..

I think he weights atleast 200kg, remember that he is very large!
He goes more than twice as fast as me equals to your equation :P
Since a Lockheed Martin F-22 goes 2964.6kph fast, Toothless speed times 4, and weights 14 365 kg when it's empty, it means that Toothless for his weight, is really fast!

I don't think that he would be able to fly if he would weight 200kg. Dragons have like birds and some dinasaurs very light bones with large air-filled cavities.

And the speed of the F-22 is not the free fall speed. When Toothless fly on a horizontal line he could reach around 200 km/h (which is nearly twice as high as the speed of a falcon).
