Fixed wing aircraft work by using a kind of propeller or engine to pull the aircraft forward and the wings produce lift.

When they don't work!
Of course they work - didn't you ever see an airplane flying?
Airplanes.
No. Gliders, jets and rocket-propelled aircraft do not have propellers.
RTF airplanes also known as "Ready to Fly Airplanes" are airplanes that are already put together and require only a little bit of assembling. I obtained this information from this website: http://www.mostrealisticai.com/rc-airplane-kits.html
The technology on airplanes is not old, the concept of some things might be and it is simply because they work and they are reliable.
As I work on Boeing 747's, I can confirm they do have Windscreen Wipers.
Of course you could use fleet software to keep maintenance records for airplanes. You can get information on aircraft maintenance software at http://www.capterra.com/aviation-maintenance-software
Old Airplanes and new are similar because they work under the same principles. Creating enough lift to become airbourne. To do so a plane needs to be light enough with enough thrust and enough surface area of the wings to create the lift
All gliders are airplanes, but not all airplanes are gliders.
