I also have been considering trimming a plane with flames and have seen quite a few planes here on RCU with them.

Although I highly appreciate the covering job on Juice's plane (it looks awesome), my personal preference is fewer flame tails - like only 2-4 large tails per wing panel.

There's some REALLY nice flame jobs in the Fun Flying Planes and Profile Planes forum right here on RCU. Look for Termagator (Gator) and flames. You won't be disappointed.
