I know the rules and updates state that energy can't be stored for the vertical projection (basically no launching, just climbing) of the minibot, or by the hostbot.
However, imagine this scenario:
Your minibot is powered by the battery, and uses motors and wheels to actually climb like intended. However, you also have a coiled up, lets say, antenna, that is unraveled after deployment, and all it does is stick straight up, and acts like a little flagpost. (Perfect for any teams with a pirate theme.

) Note that it would remain within the 12x12x12 volume constraints.
It does not help propel the minibot up, but it is "stored" energy, (by being coiled up).
I read through the rules several times but could not determine if this would be legal.
Thoughts?
