I have finished both engines for the duo this week.
Wildcat's P&W R-1830 Twin Wasp is nicely done and you even have exhaust pipes at the back, although they are of same length and don't reach the front cylinder row. The electric wiring, the ring and spark plug cables are made of photo-etched parts, are extremely thin and can hardly be seen in the photo.
Dauntless' Wright R-1820 Cyclone engine is also nicely moulded, however, there is no electric wiring provided, so I created it using various diameter lead wires. Tedious work but in the end, I think it was more than worth it.
