It is all mass dependent, the feeder weighs between 50 and 70g depending on the size of the vessel used, which is dependent on the type of feed used.This means that you can fly out about 350-450g of feed at a time if only feed is flown out. If you are flying out your fishing rig at the same time then the feed amount drops accordingly, we typically fly 200g feed with our 200g lead sinker and fishing rig. This might not sound like allot but it is more than enough. If more feed is required simply fly out a second time and by using the GPS saved map you can drop it in the exact same spot as before time and time again, advanced pilots can even use the fly to waypoint feature and let the drone do it all on its own, just remember the DJI limit for waypoints are only 500m from takeoff point.
