Wingnut wings complete and utter brilliance is a double edged sword.
They completely dominate the 1/32 WW1 aviation market in a way no other company manages in any other market. They've got the resources, the money, the time & the desire to make any model they fancy.
This makes it very, very difficult to compete against them. Special Hobby's Bristol MC1 is a great little kit, beautifully made, but it's a limited run kit and hence lacks the engineering, detail & ease of WNW. But the price more than makes up for any shortcomings and I hope it's been a success for them and they follow it up with more WW1 subjects.
Look at Roden, who previously carried the flame for 1/32 WW1 modelling. I remember their Albatros being reviewed in Windsock as the best thing since sliced bread. Now it's completely outclassed and sells relatively cheaply. They simply cannot compete & have exited the 1/32 development market.
So with WW1 aviation modelling still being a small niche, and WNW taking up a great big slice of that niche - in 1/32 anyway - there is simply insufficient residual demand for anybody to compete with WNW, other than the odd limited run kit.
We'll see all sorts of Spitfires, P-51's. 109, 190's, etc, as the market seems absolutely massive for WWII kits, to say nothing of the jet market.
I'm extremely happy & glad that WNW have given us models we'd never dreamed of only a few years ago. But it also means they've largely killed the competition stone dead.
