Thank's Obamot,
" The silver wrench"
the "SIVER BIRD" has a command instant adjustment of the wind which should enable it to make circles in a parking under wind, for example, with the maximum turning radius.
Continue the fun: I call this command very atypical " silver wrench."
On the picture it's the "bielle de réglage en continu d'incidence au vent"
You'll see on future video as it is nice ... this sivler wrench
have a great day
Pascal
