I've purchased 6 Yahu IP panels in 1/48 scale, and so far have used one of them. To say that I was impressed, would be an understatement. These IPs are by far the best I've ever seen.
The IPs are the correct color and texture, unlike many of the Eduard Color PE Panels. And the Instruments look exactly like scaled down ones.
The IPs are honestly worth twice the retail price. they're that good.
