The Wright Brothers put propellers on all of their planes. There were no jet engines then.
there are no propllers on planes but there are on helicopters
Yes the ash would build up and clog the air filters to the combustion chamber
Early aircraft propellers were made out of solid or laminated wood with later, more modern propellers being constructed from metal. The latest propeller designs are made out of composite materials.
No, because propellers do not power anything. The engines of the planes power the propeller to get the plane propelled through the air.
For starters, planes today use many different forms of propulsion such as jet, pulse jet, jump jet, rocket, and propellers. The planes in WWI only used propellers. Also, the amount of technology in the planes has increased a thousand fold. Planes today can take off, fly, and then land themselves, all on auto pilot. Physical pilots are there in case a.) something goes wrong and b.) for the passengers. Tell me you wouldn't be nervous if there was nobody on the plane who could fly it if things got sticky.
According to studies, airplanes are 9 times faster than cars. It is because they are powered with greater thrust by propellers and jet engines.
If it is an electric RC plane then all you will need to pay for is the plane and if you plan on crashing a lot some spare propellers if it is an RTF or ready to fly version. If it is an ARF or almost ready to fly you will have to buy a motor too.
Before, airplanes were more mauneverable and faster, they were hard to control and very slow. Before the planes were powered by jet engines and turbofans, they were powered by propellers.

The first planes started as gliders, then it moved onto propellers. Eventually after years the first jet plane was made in WWII, by the German sides.
Lang Propellers was created in 1913.
