Conditions That Allow the Front Foot to Flip the Board
Mechanism / Why It Happens
If the board does not flip no matter how hard you swing your front foot, you may not be creating a board position that the front foot can easily catch.
As explained in another Tip (Link), there are two ways to give the board its flip in a treflip: using the front foot, or using only the back foot. A common failure pattern with the front-foot method is stomping the tail too hard. This causes the board to rotate significantly while it is still in contact with the ground, so when the front foot tries to flick the board, it cuts through the air. There is nothing wrong with popping the tail strongly in the vertical direction, but the problem is that an excessive focus on what is often called the scoop causes the board to rotate too much horizontally. For more details on the scooping motion, see here (Link).
Analyze
Check the angle of the board when the back foot leaves the tail.
The cause of the problem is stomping the tail too hard. When you check your own movement, if the board has already rotated more than 45 degrees before it lifts into the air, you can say that unnecessary force is being applied to the tail.
