It is a Sea Plane I have made it entirely using parts from only one Unimog 8110 set. The one exception is the propeller part which is from set 8855. It uses approx 1500 parts. I have been building My own Technic designs for about a year and this is my 6th ever..
It is not specific to any particular model of sea plane. I simply set out to capture all the key features and characteristics that a sea plane should have and then try to find creative ways to solve the design challenges when using only one set for parts, Even if it is the largest set of parts to choose from. ..
Motorized compressor and pneumatics.
The same Motor drives the pistons and prop and compressor.
There are 3 pneumatic switches in the cockpit. The left one controls the left aileron up and down. The right one controls the right aileron up and down. the one in the front center controls the rudder left and right.
There is a fourth pneumatic switch at the rear bottom of the plane. it is used as a regulating valve and is not connected to anything on the output. This enables you to demonstrate the engine and prop without creating any pressure in the air system. you can use it as a pressure relief. Or you may use it for fine tuning of pneumatic functions for a slower more controlled response by allowing only a tiny amount of air to escape constantly..
The Pontoons have small gears mounted in them to act as wheels so you can push it along nicely.

i think this is seriously awesome how long do models usually take you to design and build?
I built the plane for a competition over about 3 weeks. Most of my models take between 1 and 4 weeks. I work during the day so I can only do them in some evenings and on weekends. For me the keys to building are to take a break if I get stuck on the design and to not be scared to rebuild sections if it will improve the overall final design. for example I rebuilt the wing design 4 times.
