If we are forced to fly a plane it would have the number of steps on the aircraft chart. Since that wasn't there and the rules stated that we can fly whatever, I do not believe we had to fly anything and could fly what we choose from the list.
Look at the BBD aircraft tables:
http://www.squadselectseries.com/events/BBD/BBDAC.htmlThose dictate the number of frames each plane needs to be flown. We did not have those restrictions this series.
The Buff's flew TBD's all 4 frames. The NS were the only squad with the option of the F6F. We flew the F6F 3 out of 4 weeks.
