Thanks Smiley.
The smaller wood props like this one are only about $6.00. This is a 14x5.
14" in length 5" Pitch=one revolution moves prop forward 5", like a screw.
Both the wood and composite props start to get expensive when they get to 16" length or greater. The most expensive props are the carbon fiber.
The two silicone lines going to the silencer/muffler are pink/red for fuel tank pressuration which gives better fuel delivery to the carb., and the other yellow is a tap back into the crankcase, which helps scavange excess oil out and provide pressure equalization for a more consistent fuel mixture whether the fuel tank is full or near empty.
There is one blue line you can't see inside the cowl that delivers fuel to the carburetor. This fuel line to the carb has a section of fuel line attached to a weighted clunk inside the tank so that fuel is delivered to the engine no matter what the plane orentation is.
There is another fuel line to the tank that sticks out the left side of the cowl which is for fueling/defueling. This also has a piece of tubing and a clunk inside the tank so when you defuel the plane, all the fuel gets sucked out.
