We used to use a kite to take our Bonita out into the deep water when we would camp overnight on Honeymoon Island... Stick your rod into a PVC holder on shore, set the spool unlocked with the clicker on and go sit by the campfire with your beer...and hopefully you weren't too far gone to notice the clicker going ziiiiiing before you ran out of line on the spool.
(used to get Blacktip, Lemon and Bull sharks mostly in Dunedin area) Shark is sorta ok to eat smoked...so maybe a lipo fire could enhance that... shark has kind of a strong gamey taste otherwise...
Drone's would be great for getting model rockets out of tree's, just put a mini winch and a hook... heh.
Ummm... let's see... trying to get on topic for C/L Stunt... Oh! Drones could be used as score runners at contest! (Or prolly a better idea is to just give the judges Ipads, and write some scoring software, then you would get instant results too...)
