5 hours isn't bad for your first wing, it will get better/easier. But are you in a hurry or rather get it right? Like I try to tell all the new builders, take your time and enjoy the process as much as you can. Don't make a job out of it or set too tight (if any) of a schedule. It'll be done when it is done. HEY, this is supposed to be fun, not work. Later on when you start adding a lot of trim to your covering, 5 hrs will seem fast.

Ask Kiswa or Krossk how many hours they took or even RCken on the lt-40 project.
