Before you try Bs axles, you should do Bs "slashes": backside kickturns "slashing" the coping with your back truck. When you dominate Bs (or Fs) slash, the board don't do "bad things" under (or out) your feet, and you are ready to try the real axle stalls (Pd: this is a good example of what i want to tell you: https://m.youtube.com/watch?v=_328mrfYILc check it bro)

when you're kick turning into the coping make sure your back truck locks in and then bring your other truck to the coping. if you're on small coping make sure you're balanced well

be more precise!!! when your tail truck arrive on the curb you have to start the rotation!!!

turn shoulder

Try to go a little slower and attempt to kind of throw your body up right on top of the coping of the quarter

Lean back and keep your wheight center over your board

Just commit

All good answers dude. You just have to practice and commit🤘🏽

Commit and work on timing

Lean back a bit more

Exaggerate the turn

As you come up to the top of the coping rotate your shoulders halfway and stand up straight more on your heels use your core to plant yourself.

When you approach the coping stay low and as you rotate your shoulders stand up and plant your self centered on the board may be a little more on your heels use your core strength practice dropping in from the axle stall position to get comfortable on the coping and make sure your trucks are loose enough.

Stand up straight use your core come in low rotate your shoulders as you log into the coping and plant yourself practice dropping in from this position

Try to go slower and at a more smooth angle. It's easier to check-list every little step when you're not blasting yourself directly out of the ramp. Just remember to bend your knees and wait until you hear/feel your back truck hit the copping before lowering your board. Hope this helps.
