Query: Not a well designed toy.

We purchased this toy for your 4 year old. He loves Rescue Heroes, but this toy doesn't get much use. It is very difficult to put any figure in the seat. It takes a lot of effort to make the blades spin, and they spin for only a short time for each pull. Finally, it is awkward to hold and "pretend-fly" with, as there isn't any convenient handle.
