Phil, it's a turbo tail. The profile is basically rectangular instead of upswept and wing shaped like a carrera tail.

Yes, It's a turbo tail. I thought all tails were Whale tail. Learn something new every day.

Tail Tail Tail!!!

Thanks Steve

I knew that the turbo tail had the edges of the tail upswept (like a tea tray) but I couldn't tell from that pic what it was. It looked like it had a higher profile off of the lid than a carrera tail. thanks for the confirmation.
