It is really no problem to get the waiver, at least that has been my experience. Our Super Decathlon weighs 75#. It's been a year so it is time to do it again. In 39 flights at several Big Bird flyins I have never been asked to see the waiver. Chances are pretty slim that you will ever be asked about the waiver with your bomber. In my case I didn't want to drive 300 miles to a flyin and have someone reject the plane for lack of a waiver.
