Eduard is a monolith when it comes to etch sets, but I’ll be honest, while there’s nothing wrong with their product, dig a little deeper and there’s better stuff out there… so long as it’s for the plane your keen on building, of course.
Microdesign was unknown to me until they popped on Scalemates with their upcoming etch set for the Zvezda Su-33 Flanker. The set looks pretty comprehensive, and while described as being in colour, the accompanying image shows both a colour illustration and natural brass. So, yet to be determined what’s going on there, but this could be a banger addition to your Flanker build.
