HGUC #56 RX-121-1 Gundam TR-1 Hazel Custom


For those unfamiliar, the RX-121-1 Gundam TR-1 Hazel Custom originates from the famous Advance of Zeta: The Flag of Titans manga. This series takes place in UC 0084 and follows the Titans Test Team doing Mobile Suit testing and engaging in actual combat against various opponents. The “Hazel” line of Mobile Suits has a vast and diverse development history, which is why they are so popular despite not having an anime adaptation.

Included with the RX-121-1 Gundam TR-1 Hazel Custom is:

  • Beam Rifle
  • Beam Saber
  • Standard Shield
  • Booster Shield


This model kit shares multiple parts with the HGUC #69 RX-121-2 Gundam TR-1 Hazel II. The construction of this model kit should feel very similar to you if you’ve built an Earth Federation model from around this time period. The Booster unit articulates backward and rotates to attach the Shield booster to the backpack. This kit does not include an action base adapter, nor does it have a 3mm peg hole on its underside. If you’d like to display your RX-121-1 Gundam TR-1 Hazel Custom in a flying pose, use one of the U-shaped base adapters included with the Action Bases. A better option would be to drill your own 3mm peg hole so the model doesn’t change positions over time.

Weapons and Other Notable Attributes 

The included Shield Booster can be equipped on the backpack, as well as on the forearm of the Gundam. Be sure to combine your RX-121-1 Gundam TR-1 Hazel Custom with the other excellent HG Advance of Zeta model kits!

Tips and Tricks –

By implementing the technique of Top Coating, you can do a great deal to help preserve the longevity of your models. This process will protect the original plastic of your model kit and prepare it for any additional modeling techniques to follow.

You can drastically improve your results by making the details pop on the HGUC #56 RX-121-1 Gundam TR-1 Hazel Custom with Panel Lining. The simplest solution for this is Gundam Markers or Tamiya Panel Line Fluid. If you’re up to a challenge making panel wash is always a great option too! It is always recommended to Topcoat with clear gloss beforehand, as some of the products commonly used for Panel Lining will degrade the untreated plastics over time.

Another way to keep adding detail is by applying Stickers/Marking DecalsTop Coating before the application will help decals stick to the surface much better. Using Top Coat after application will help hide the seams on traditional sticker decals as well as waterslides. This additional step will also keep them from peeling over time. Using Decals is a great way to add an even greater level of detail to your scale models.
