The WC Pioneer team has also been looking for suggestions on turret cockpit designs. A number of people have already submitted concept proposals based on required criteria. Some have even modeled possible exterior shots. Here's a few of the submissions.here.
Okay, ladies and gents - here's the first turret completed from the concepts you guys have made. This is the tail turret for the Camel - it's built after the concept presented by Maj Striker. The main reason I like it is its extreme range of movement - a normal ball turret only has about 60 degrees of movement in any given direction. This sucker has almost 85 degrees. The only thing that might be considered a downside is that it looks a bit like the head of an AT-AT from Star Wars. But eh... only a little bit.
