Is one permitted to fly a kite on Shabbat? Assuming that there is an Eiruv, would it be permitted?
Dinonline Flying a Kite on shabbat answers,
The actual flying of a kite itself does not involve a Shabbos prohibition [when there is an eruv]. However, this is not a recommended activity on Shabbos. Very often a kite has to be fixed, put together or reattached, all of which are prohibited on Shabbos. In addition the string often becomes knotted and may not be undone on Shabbos. It is also likely that this activity is not in the spirit of Shabbos
The Mishna in Beitzah 36b lists a number of things prohibited by Rabbinic law as they may lead to Shabbos transgression. Logic would dictate that this activity should be included as well. However we do not have the authority to add new gzeirot (decrees), and so this activity can not be strictly prohibited.
