Uh, yeah, the arms look to be 180 degrees off - just like Cowl, LOL!
I was waiting for a build on one of these, but I thought all of their ARF's were now HP ARF's with pre-made engine box and hinges predone, etc.?
Did you iron the covering before you started? It is recommended that you run a medium heat covering iron over the Oracover before you stat putting things in to make sure all the seams will stay down. You don't want to be flying it on your 3rd or 4th flight and start having your covering come apart.
