The RC pterodactyl in Wargames symbolized Steven Falcon's supreme intelligence over ordinary people who just flew model cessnas.  The lion kingdom believes the movie prop actually flew.  

It had transparent vertical stabilizers in a few frames.  It raised its legs to pitch up & lowered its legs to pitch down, as a form of weight shift.  It turned its head to yaw.  There are ways to get wing warping by making large servo horns.

There are very low fidelity toy pterodactyls from China.  The movie prop was a glider rather than an ornithopter.  A higher quality movie prop replica would require manely a lot of old fashioned latex & canvas modeling.
