HGUC RB-79 Ball Twin Set

HGUC RB-79 Ball Twin Set landed on 11 September 2010 as a value two-pack, bundling a pair of mass-production Balls with interchangeable cannon options at a ¥1,300 list price.1

Overview

The release targets Universal Century diorama builders, providing two core pods and both the standard 180 mm low-recoil cannon and the double cannon variant in one box.1 Each unit mirrors the 0083 animation proportions and arrives with its own clear display stand.

Features

  • Dual weapon load-out per Ball: swap between the low-recoil cannon or twin cannon without tools.1
  • Dedicated stands per unit with adapters sized for Action Base compatibility, enabling aerial fleet configurations.
  • Fully articulated manipulator claws with hinged elbow segments for expressive repairs or combat setups.
  • Shared runner system with the GM Type C release, simplifying part replacement if mixing kits.

Build experience

Assembly is brisk—each Ball comprises symmetrical halves with minimal seam clean-up. Pay attention to the transparent cockpit parts; masking before topcoat prevents frosting. The ABS internal arms benefit from a light application of lubricant or graphite to preserve movement over time.

Kit content

  • RB-79 Ball units (x2)
  • 180 mm low-recoil cannon assemblies (x2)
  • Double cannon assemblies (x2)
  • Display stands with detachable Action Base-compatible pegs (x2)
  • Manipulator arm sets with ball-jointed elbows

Colour guide

Awaiting official manual breakdown. Capture the manual’s ratios for the off-white hull, grey framework, and yellow viewport glazing once the data is transcribed.2

Comparisons

Compared with single-pack Ball releases, this twin set halves the cost per unit and adds variant cannons, making it ideal for fleet displays. Paired with the HGUC GM Type C & Ball Type C exclusive set, it rounds out a full Earth Federation hanger.

Official assets

Coming soon. Prepare the Bandai stock photography set to showcase both cannon configurations and the clear stands.
