Though that's not inviting you to take your plane for a swim! JKFrom experience: water and electronics is not much of a problem anymore. Worst case put reciever in a baggie. Cant do much protection for the ESC's but everyone is happy if you leave wet stuff in the sun for a day (at least here in Reno) servos tend to be water resistant or not. Typical failure mode: corrosion breaking circuit or bridging another. If stull looks like mold on the boards a good toothbrushing will often fix it. Not like todays equipment costs a months take home any more.
Might suggest building something that uses your wingspan to get experience building structure favoring foamboards. Mostly you will have a skin failure inwards crease that leads to wing fold up, but arrow shafts and fishing rod blanks are super neat spars and plain clear pine appropriate sizing works well. Don't need oak.
