About this 3D model

I've been meaning to make a simple airboat for several years, in fact when I was younger I tried to build one unfortunately I never got around the remote control part. It works :-D. The direction mechanism needs some adjustments (fins, fins support, gear) to improve the turning radius, despite this it works rather well. Printed using with a E3D v6 with a .4 nozzle and PLA Instructions: For this you will need two soda plastic bottles, I'm using two 1.5 liters bottles and a cheap rc car (I just bought the cheapest I could find, around 10€), tear it apart, you just need the eletronics bit. Also a couple of zip ties (with diferent lengths), to secure everything. Print two fins (fin.stl) The base arcs require supports
