RE: another GP Viper question..
Except for the tail... everything is pretty close and easy to make perfect... that digital level is "boss". My old fashioned analog "eyeballing" tools are jealous. If you didn't glue the tall on that is a real easy fix. If you glued the tail on... just carefully saw it off and reset... been there done that - only takes about an hour start to finish with a razer saw. Don't even try to go through the glue joint - go just beneath it. Good luck.
