Hello everybody,

This is my first helicopter animation. Let me know what you think!

http://www.youtube.com/watch?v=Yjs_qcL7jx0

And I do notice the end of the rotor blades is a bit weird. I have no idea how that happened cause I just slowed it down, I didn't reverse it. Or is that realistic?

Regards and succes on future projects,

you'll need to model in a landing pad or something so that we can really see it fly..looks like you're off to a good start though

Yeah.. I should have.. However.. hes perfectly standing on the grid when he lifts off and when he lands.. so thats okey..

The thing i dont understand is why the rotor blades act so weird at the end..

i animated it really good..

heres how i animated the rotor blades..

Left = Frame. Right = Y-axis

0_0

50_-400

100_-800

150_-1600

200_-3200

250_-6400

300_-9600

350_-12800

400_-16000

450_-1600

500_-800

550_-400

600_0

Maybe I slowed it down too late??

tell me what you think...

Regards,

Hi ehm.. Im not meaning to be impolite.. But im still waiting for an answer.. Whats wrong with the animation.. is it really turning out so weird because i just slowed it down to late?

Sorry, I'm not really that well versed on the program yet, I can only reply to it from a standpoint of being in the military and watching Helo's fly....that said, it does appear that you slowed it down to soon. In life if a helo dropped it's speed that quickly, it would have a hard landing. Also, getting back to the idea of a pad...if there was a defined ground with a different color it would help. In vietnam the pilots were always in a hurry, they would flair the tail to, as I understand it, get it down quicker..might want to see if there are any helo videos on google that show this...good luck.

That might be a visual problem, like when you see car wheels spining backwards even when the car goes forward. But besides that, I think you do have a problem and that you should interpolate those frames instead of keyframing so much. I think that chopper should fall from the sky if those blades stop spining so fast ! You should also try to anticipate a little, the animation is to straight forward !
CHEERS !

hey man, the problem is that you reverse the rotation of the blades.. you go to -16000 in the y-axis, but they return to -1600... it should continue to go in the same direction (ie, the y-axis should continue to go into the negative..... so, instead of from -16000 to -1600, you need to go from -16000 to -17000... and so on..)

you just have to adjust the rate at which it goes into the negative to slow it down..

but other than that, I'd say wait a bit before lifting off.. once the propeller gets up to full speed, a chopper would still take a few seconds before lifting.. just a minor thing though..

hope this helps..

you also might want to check the animation curves - try linear tangents to avoid any "rubber band" effect of the blade... it'll be a little stiffer but would look more proper.

I've figured it all out. Thank you all so much for helping me with my problem!
