Fishing Airplane

[AK rc]

Hey all,
I am working on an fishing airplane project and could use some insight.

Mission objectives: An airplane that can deliver 12-16 oz of bait (6-8 in herring) and lead 200-300 yards out to sea and fly back. Able to land in slightly wet sand(I will avoid dry sand), pebbly surfaces without damage. Stable flight in moderate wind(10-15 mph).

I am a proficient builder and pilot. I am looking at a bait dropping system with three attachment points. One in the middle of the aircraft at the cg so once the payload is released the cg should remain unchanged. this will be the single big bait missions. Two and three will be on some outside at the cg with releases tied into the main drop so I can also do drops of lighter jigs(1-2 oz) one at a time for when I am fishing with a buddy. Entanglement is a big concern. I am wondering about adding a magnet or two on the fuselage towards the fail and then using a ring on the line to keep the line under the tail while in flight, but then be easily disconnected on release. Any other options or questions I need to be thinking about?

I am leaning toward the Ft guinea, though I have an founder ft legacy kit unbuilt. I think the legacy would need to be modified to make a large enough cargo hold at the cg point to meet my needs. What are your guys thoughts on the two options? Any issues with the wing loading? Would increasing wing span by 6 in be worth it? Does the wing need any additional supports to handle the weight? Of course any other issues I need to be thinking about?

Thanks and I will post updates and hopefully some mission success photos.

I would suggest carrying the payload on the outside of the plane with a single release point under the CG. No real advantage to carrying this type of payload internally. Easier and more flexible to carry it externally. So I would use the FT Legacy. I am not sure trying to pull three lines out at the same time is a good idea as the risk of tangling the lines is high. Could be easier and more reliable to make three trips instead. But if I was going to pull three lines at once I would put the two lighter payload connections on the wing tips for the maximum spread between the lines and not make any turns before dropping the lines.

The weight of the line will keep it under the tail. You don't want a connection point behind the CG or the weight and drag of the line could pull the tail down.

The drag from the line coming off the reel, thru the guides and the line itself is going to be the biggest concern, a quad may be a better delivery system. Keep us updated of how it works out.

I would either do the one big bait rig or the two smaller jig rigs. Never three at a time. One of my concerns about having bait and weight outside the plane is it tangling it's self up before it gets dropped. K, I will get going on the Legacy build and should have some pics up this weekend.

Quads probably would be a better system, though I am not sure how much better. I should be able to make more trips per battery with an airplane. (getting batteries in Alaska is a pain in the wallet) I also have everything I would need to build a plane already.
