I am trying to animate a skateboard doing a trick called a hardflip. The trick involves the skateboard rotating 180 degrees and flipping once. If I animate the whole trick with two keys, it make it look weird because it involves the flip and rotation. To solve this I split it up and put two keyframes. Then on the second one, I rotated the board halfway, and flipped it over halfway. Then I put a third key and on that one I flipped and rotated the board the rest of the way. The problem is, since the animation is split into three keys instead of two, it looks like the board rotates half way, slows down a bit, then speeds up into the second half of the rotation. Is there a way I can make it look smoother? The image shows the timeline, and circles are over the main 3 keys. The other are just to adjust poses.
