Had my first nose down toss today. No fun and hurt. Riding in classic mode, pavement and accelerated hard while already moving. Couldn't run it out and took a big dive into the pavement. Thought I broke my hand but got lucky. Just some scrapes, torn clothes, swollen hand and bruised pride.
From now on helmet and gloves/braces. Nice little warning that even a toy as fun as this can still bite you.
