This is a concept that happened by purely by accident. However, I liked the idea... so I continued to make two additional planes based on the same design.
These planes could actually be used in a children's book, an animation for children or even a game. I feel the target audience would be roughly between ages 5 to 7.
The idea for a game could be quite simple. Take off, fly a plane over mountains and around obstacles.... drop off packages above buildings... rescue people and then land. Maybe additional points for doing tricks. As points are earned one could trade them in for different models of planes that have different special skills. If created as a game I would go for a very simple UI. And probably market the game as a mobile app.
Creating a non-violent adventure would be something that parents would enjoy letting their children play.
