Sorry Ary, but what is really changed? The Keel is the fin/blade and the longest part of the guide, hence the only component of the guide that could be visible from under the nose. Also, how is this different from any other series where the general rule is that – from above, you are not allowed to have any part of the guide (aka. the keel/blade) visible from under the body, spoiler or the chassis.
What am I not understanding … I do not understand the impact of the change b/c it appears there is no effective change.
