Hi Narrak,
The first thing you should know is that every launch will be a bit
different from the next, depending mostly on the
wind strength but also
kite size. The launching technique you explain (50% trim, bar out and slight pull of the steering line) would ONLY be a good/safe/effective technique in strong/very strong winds (i.e. 25 knots + ), essentially when you know you're
overpowered. - If you're using your kite in it's intended wind range (i.e. not overpowered) then you wouldn't want to trim it at all during the launching phase (that's of course assuming your lines are correctly tuned and all the same length).
- Regardless of the wind speed or kite size, you first have to have the right position (angle) between the kite and the wind direction, which typically corresponds to about 90 degrees. This angle will be greater in light winds (less than 15 knots = walk more upwind) and lesser in very strong winds (25 knots or more = walk more downwind).
Basically,
without touching the bar (so bar is at full depower) your kite
shouldn't be flapping while the assistant is holding it correctly. If the kite is flapping, then you're
underpowered and you should walk a few more steps
upwind. If the assistant is getting dragged while holding your kite, that's your fault/responsibility and you're either too far upwind and/or puling the bar too much, if that's the case, walk a few steps downwind and/or let go the bar.
- So assuming you have the correct position (kite is not flapping and assistant is not getting dragged) then grab the bar and
pull the bar IN until the back lines have a minimum of tension (not dangling) AND you can feel a slight steering response (kite wants to go up) by steering the bar. How much you pull that bar in entirely depending on the wind speed/kite size/your position in relation to the kite and wind so there is
no universal way here. - If you don't have any tension in your back lines, your kite will launch underpowered and you won't have any control over it, which would explain the behavior you described. Pulling a steering line in that case would only oversteer it and likely bring it to the power zone.
- If the wind is not too strong (below 20 knots) it's typically best to launch the kite with a bit of power and steering so it has a bit of momentum when the assistant let's it go. As the kite rises up, simply push the bar out a bit and release a bit of steering, this will ensure it travels at the edge of window and not in the power zone. Remember that the wind strength you have at beach level can be quite different (a lot less) than the wind you have 24m above the ground.
So in summary: no flapping of the canopy, pull the bar until you can feel a steering response, use the bar and not the lines to bring it up and sheet out/steer less as the kite rises and don't use your trim unless you're overpowered. Also, never pull the bar all the way in when launching a kite...that's a problem you don't seem to have but it's very common among newbies...
