The Ripperdactyl Riders and Terradon Riders kit is a dual-build — the same sprue makes either unit, so the choice comes down to your list. Both ride pterosaur-style mounts on flight stands, both sit on 50mm round bases, and both share the same magnetization needs: a flight stand that holds the model up without snapping, and a base solution that locks them into a case for transport.
Flight Stands for Ripperdactyls and Terradons
The flying mount on each rider sits at the height where the Medium Tall variant of the posable flight stand fits cleanly. The ball-and-socket joint lets you angle the model in a swooping pose without the stand cracking — a common failure point on the stock GW clear stand once you have any paint or pressure on it.

Base Magnets for 50mm Round Bases
Both Ripperdactyl Riders and Terradon Riders use 50mm round bases. If you already have the bases and just want them magnetized for case transport, the Peel & Stick inner base magnet drops into the underside of a standard Citadel 50mm base — no drilling, no glue.

If you need replacement bases entirely, the pre-magnetized 50mm round bases come with the magnet slots and magnets ready to glue in.
