You could look at the Kaydem and say it’s a Blasterscoot without hands - and it actually is. But maybe you’re also noticing that it’s an Aerial, where the jumping foot stays planted. To perform a Kaydem, you’re going to swing your upper body downwards and to the side, while you simultanously swing your leg around, like you would in a Blasterscoot. Try to move your upper body fast and whippy. It’s the same motion you would use for an Aerial. Spot the ground.
