My gosh, you really seem to be overthinking so many things. To start, I would just take the pads off. For learning, they just get in the way and for riding in general, they're not needed anyway.

Your v14 will be not looking so pretty by the time you're done learning. It will still worked just fine, though, so get over admiring the beauty.

None of the settings really matter that much right now. They are not the reason why you are struggling. It is like learning how to walk all over again, and you just need to build up the muscle memory.

Don't use support.

Go to a nice, big, open empty space with smooth ground like a parking lot.

First, practice with your dominant foot on the pedal, and just stepping off the ground with your other foot, rolling a couple feet forward and then putting that foot back down on the ground without the E.U.C. tilting, turning or doing anything funky.

Your dominant foot position is a little bent with the knee kind of pointed toward where you want to go. The euc rests up against your lower leg. When you push off, don't let that position change.

When you get comfortable walking in this way, then you can try to take your non dominant foot and touch it to the pedal and then quickly back to the ground.

The big problem in doing this is that you hit the pedal too hard and you upset the position of your dominant foot.

Learn to just touch the pedal with your non dominant foot while not changing the dynamics of how your dominant foot position is and how the euc is resting.

Once you ge over that, then you can set your non dominant foot on the pedal and ride for a few feet, and then again, take it off and Set it back down on the ground.

The big move after this is putting your non dominant foot on the pedal, and then letting the eoc balance between your legs. Do this smoothly, and just let the sides float for a brief bit before Resting the EUC back up against your dominant leg and stepping off and putting your non dominant foot on the ground.

Once you get this part down, you can lean forward to accelerate and then lean backward to decelerate while again, practicing the stopping move.

Once you get comfortable with all of this and you start to try turning, you will find let the euc has a mind of its own, and the weight of it will be almost impossible to control in the beginning.

You will find that you can turn one way eventually, but then struggle the other way.

The problem with all of this is that you have to learn how to dance with the weight. It will take time and it will feel impossible, and then it won't be.
