Thanks for your replies
Again, I'm a noob when it comes to rams and unfortunately there is no one familiar locally to help. (one of the problems of frequently windy areas...)
It's not yet possible for me to figure out what is the low end for launching or keeping it in the air. (that's one of the things I'm currently learning /experiencing)
My enthusiasm may push me to try in conditions that it is not possible even for a more skilled person.
Luckily, the place I kite is frequently windy (my 10m switchblade is at least barely rideable 150+ days per year) and the shore is so "curly" that we can always pick a sideshore spot within 20 kms, even if we sometimes have to launch the LEIs between trees, above bushes or other kites etc.
I'm trying the ram during the days that I know the 10m switchblade will be a struggle to keep upwind in best case till days with almost no wind.
During these days there is usually a thermal onshore breeze and enough swimmers to make kite launching possible only in very few spots. (As a local community we religiously keep at least 200m from swimmers and other non-kiters)
The beach is long but not wide. The distance between the water and the road above is 30% smaller than my kite+bridle lines.
That means that when I need to do a downwind launch (onshore wind), it’s a hybrid… and I’m already in the water which deep fast. (i.e. no backwards running option)
Moreover, there is a natural pebble bump about a meter high, 2-3 meters from the water, that kills the ground wind downwind from it…
The vacuum cleaner, compared to a leafblower has the advantage that if you figure out you do not need it, you can use it at home
