Brengun, from the Czech Republic, specializes in aftermarket details; for the most part releasing drop-in resin or photoetch replacement parts.
This set is intended to enhance the 1/48 Skyhawk A-4 C/E/F/M. This set can be used with any of the 1/48 Skyhawk kits, like the Hasegawa, ESCI/AMT/Italeri, Hobbycraft, HobbyBoss, or Monogram. If I am missing any other maker in the list, it is an honest mistake on my end.
Please note that the instructions list the variant of the airplane to be in 1/72. That is clearly a mistake, this set is molded in 1/48 scale.
The parts are molded in grey resin, free of bubbles or imperfections and with great surface detail. The attachment points to the casting blocks are miniscule and removal and clean up should be an easy task.
I do not think the RATO rockets saw widespread use in the Skyhawk fleet, so you might want to do some research as to which version, or even down to tail number you are modeling.
Highly recommended to modelers of all skills, except perhaps the most novice.
I would like to thank Brengun and IPMS/USA for the review sample.
