Hey all
Just a thought on my part. The engines in the B-24's were P&W R-1830 dual 7 cylinder radials.
The ones in the kit are a pretty poor representation of them. You can get resin replacements for them, but they are expensive. I found out that the B-24, DC3 and the Grumman Wildcat all had the same engines. So I went on the internet and found on Ebay the engine sprue for Trumpeters 1/32 Wildcat kit for I belive $17.00 bucks. It's fairly well detailed, the only thing that needs to change from the Wildcat to the Liberator engine is the front gear case, it has twin magnetos and the engines in the Lib only had a prop pitch regulator on the top of the gear case. The magnetos were on the rear of the engine. Its a simple fix, snip, snip some filling and sanding and adding the prop regulator.
I'm working on it know when I get to a point I'll show pictures of what I'm talking about. You can Google the R-1830 and see the photos. And Wikipedia will show the P&W R-1830 and show which planes had them.
