The WH Extra is advertised at 27-28 tho... and I can see maybe a lb. in wood density variance in a plane this size...
It'll be a couple more weeks before I can get around to putting mine together, but I'll post all the info in a building article
Hey Mordib, how are you coming along with your WH Extra?
Also, I missed you at the DOGS. Hundreds of people there though, so not unusual.
