Here's my personal (not yet awake) list off the top of my head on a cold and wet morning...
hover facing the 90 degree marks
hover facing the 45 degree marks
fly forward from the hovers and reverse back to the start
fly figure 8
Tip pivots (360, 270, 180 and 90)
That's in no particular order (too early for me to be that sharp) and you can fill in your own variations of each. You will hear JB talk about "running track" and I do similar. Check out the below video and you will see me so hovers on the 90, squares, diamonds, bicycles, tip pivots, slides and reverse flight. Nothing more than basic flight patterns that you apply a little personal style to and create what you see. I actually was having a bad day I was shooting the video and you can see me casually looking around while flying because I just wasn't that into it.
If you want to see what unedited solo flying in front of a crowd looks like, check the video below. The winds were between low full sail and medium vented and switching direction (keep an eye on the foil in the background and see how it's reacting to the wind) so the conditions kept you on your toes. You'll see a lot of basic moves and track strung together - set a solid foundation and the rest is easy.
As someone who's been on both sides of that equation (and still am) I feel your pain. That being said, I seem to have managed it from another country with zero local assistance, so I'm sure it's totally possible
As you stated, you don't know what you don't know and everyone seems like an expert so you're easily led down the 'wrong' path. As a trainer, you'll know the silver lining in that is that the experience gained from the wrong direction leads to a deeper and broader understanding of the subject matter.
John's teachings are solid (and the main knowledge influence in my flying) and you will do well using his videos to learn. I had to make do with asking questions before the videos existed, so you will do fine with his videos. If you use that as a base and ask any questions you have, you will do just fine.
3? Just 1 type on the verticals, that's all. Both sides are the same - one spring on each side.Shaped like an "L" and closer to the top where it mounts to the sail. Just a quick look at someone else's kite!
The trick to any DIY attempt will be to figure out the Reflex's proportions and where the springs attach to the verticals, then scale that to whatever sail gets used. As was mentioned, there are plenty of options to attach the springs to rods, but not as many for the sail.But if you have one either worn out or an extra to mess with .....
