Important rule changes

Two important rule changes will apply from VF34 onwards. They are:

1. The flying segment of an entry must be between 60 and 90 seconds. This is a strengthening of the previous rule on time limit, which did not impose a minimum. The minimum flying time is now 60 seconds.
2. The permissable size of video file for each entry increases from 25 to 30 Megabytes, with a 10% leeway as before. This change is designed to accomodate higher resolution/higher bitrate videos.

Entrants, please revisit the competition rules to get a full understanding of what is required to enter.
