Proposed wording:

4.3.7.Race from Start to Finish
.
.
g) Overtaking must be done by overflying. The model is not in any case allowed to fly over six metres height when overtaking. The pilot being overtaken must on no account carry out any manoeuvre to impede the overtaking competitor, and must adjust his flying position to leave space for the overtaking pilot when the overtaking is finished.

4.3.9.Warnings - Eliminations
.
A TEAM SHALL BE WARNED:
.
.
h) If the pilot does not leave space for an overtaking pilot when the overtaking is finished.

i) For any other flagrant breach of the rules.

Reason:

The text about warning the fellow competitors is removed, since this is never done. This change is not significant, but done in conjunction with the other change.

With the high rotational speeds of F2C of today, the rules about pilot conduct have to be clarified, as things happen very fast. Also, all pilots strive at a minimum walking radius, leaving little free space. An overtaking pilot is required to finish his manoeuvre in three laps, but there is no corresponding requirement for the overtaken pilot to allow him to finish properly. In principle, the involved pilots should exchange their positions, which means that the overtaken pilot has to adjust his position to the right in his own frame of reference. Failing to do so should be an explicitly warnable offence.
