RC Airboat

I couldn't find an air boat that looked nice or would fit my printer, this is very roughly based on the air boat made by RCLifeOn. I have yet to test it as I just finished printing it. For the hinge on the rudder I used 12g galvanized wire. I can confirm it does float but thats about it. I'm sure its top heavy but a 9in propeller is all I had on hand so thats what I designed around. I have no experience designing boats and very rough fusion skills so if you have any improvements to be made please let me know. I have attached the Fusion 360 file if you wish to mess with it.
