The new Thunderbirds from the movie have significant variations over the originals and I have little doubt that someone will be making models of these ships. In the meantime, the originals can be found with a little determination. I appologize in advance for the length of this post.
Plastic Kits - Thunderbird 1
IMAI produced a seven-inch Thunderbird 1 (TB1) kit. Unfortunately, they have added large, ridiculous wheels. Bandai’s TB1 leaves a bit to be desired. Toyz 4 Boyz produced an 18" solid resin TB1, available either in kit form or already assembled.
Plastic Kits - Thunderbird 2
There were at least eleven variations of plastic kits of Thunderbird 2. IMAI released a TB2 Special Edition in 1/350th scale that had the correct profile. There were four variations to this kit:
1) TB2 with the Domo (a tractor-like vehicle).
2) The same as version 1 except the engine pods, legs, and some trim is in brass.
3) TB2 with all six pods and all the little vehicles that fit inside.
4) The ultimate 9" TB2 is available in the TB2 Container Dock kit.
There was a 13" TB2 with a Mole, a Thunderbird 4, Thunderbird 1, and a very poorly detailed Thunderbird 5. There was also a 1/144th scale TB2 available in foam and resin that was nearly two feet long with a 22" wingspan, and sold for more than $400.
Plastic Kits - Thunderbird 3
There are several small versions of Thunderbird 3. The most popular includes the space station (Thunderbird 5). A 16" resin TB3 kit is available from England.
Plastic Kits - Thunderbird 4
Thunderbird 4 is fairly ignored in the plastic model kit department. IMAI and Bandai produced similar TB4 kits. There was an 18" 1/24 scale model is available from England as a vacu-form kit. Toyz 4 Boyz had a solid 18" TB4 in three variations: 1) unassembled kit, 2) fully finished, and 3) solid crystal clear resin (I wanted a paperweight).
Plastic Kits - Thunderbird 5
Bandai produced a 9" model for only $10. IMAI’s TB5 makes a beautiful display piece and includes a TB3 (the space transport rocket) that docks with the TB5.
Plastic Kits -Thunderbird 6
The IMAI Thunderbird 6 model kit is actually a model of Skyship 1 from the movie Thunderbird 6. The IMAI box art features Skyship 1 with TB1, TB2, and a little bi-plane in the background. The bi-plane is actually Thunderbird 6.
Plastic Kits - Thunderbird 7
Thunderbird 7 never appeared in any of the shows or the comics. TB7 is only made by IMAI.
Plastic Kits - Tracy Island
Tracy Island kits are available in three versions, some of which include individual ships:
1) The original 1960s IMAI Tracy Island Kit.was the best.
2) IMAI’s Secret Base #2 is smaller.
3) IMAI’s Secret Base #3 (labeled International Rescue’s Secret Base on the box).
These are only a selection of the original TB models available and I hope this helps.
Enjoy your modeling...
