One of the great things about the STC is that, in hobby terms, there's not much difference between a Rhino, Predator, Razorback, Whirlwind or any of the other Rhino-based models. In fact, you should almost never buy a Rhino model because these other models all include the necessary parts to make a Rhino; plus whatever special add-ons come with the box you bought.
My box is a Predator, and as you can see it is just as easy to become a Rhino with a few well-placed magnets.
I do plan on painting the interior of the model, and the round magnet will have a painted door seam with my Chapter logo to help it blend in better.
If you are like me and use big magnets and have chunky fingers, you might have trouble getting your Rhino doors detached. Just use the sponson from that side to help pull it off. The magnet on the back of the sponsor will be closer than the magnet attached to the Rhino's interior making it an easy job.
Magnetizing the guns on the sponsons was a little more difficult. I wanted to avoid having to create any pieces and still wanted the tilt and pan of the weapon mount. So I decided to magnetize the interior of the gun halves. They go together surpisingly well, although I might need a small pair of magnets at the tip of the lascannon barrels.
What vehicles have you magnetized? And is there an easier way to change out the Predator sponson guns?
