If anyone has and would like to share a crankflip tutorial please do. Also any tips would help too.
I am having trouble with flipping/kicking.

You might have seen this but it’s probably the most popular one.
You have to jump up, keep a straight arm, kick directly down and then bring your knees up. Try doing half flips first or something if you find it easier 
I kick out with my crank flips other wise my foot gets in the way of the pedal on te way back around. also when i first learned them i stopped suddenly and used that momentum to help flip the tire and the most important thing as with every trick stay over the unicycle. you HAVE to commit. you won’t land it untill you think you will. shin pads help with that. definatly start with the zero flip to help get the flip down though.
STOP AND POP! basically just ride at a comfortable speed, stop momentarily and flip the cranks 
i wont lie to you, it takes practice. and a lot of it. but its worth it - the hardest thing for me was committing, as soon as i said, “f*ck this! i’m sick of failing”, i landed it no worries…"
good luck! i hope u land em and PRACTICE PRACTICE PRACTICE! 
This, so much. Once I stopped and popped I nailed crankflips. You really have to WANT to land the trick too - Put on some heavy music or something and don’t worry about destroying your balls.
