[Unified-mailman] Unified Aerial Competition, updates

[Howard Kleinwaks]

More UAC updates from Col Young:

>Here's some important updates for the Thursday (3-5pm) and Friday
>(11am-3pm) flight slots in Johnson.
>
>1. Effectively immediately, the 350 mah battery packs are being
>pulled back for charging. Several teams are still striving to verify
>that their planes are functional and for these, using the larger 600
>mah packs is sufficient. Please turn back any 350 mah packs in your
>possession for charging.
>
>2. Rules changes for pit crew time ops and scoring. The following
>changes will be in effect for this year's competition:
>
>a) Eggs will be handed over to the pit crew when the team airplane
>starts its initial, unloaded, flight segment.
>b) When the plane crosses its start/finish line the second time to
>conclude the unloaded flight segment, official time stops. The next
>two minutes are "free time" for the pit crew and pilot to retrieve
>the airplane and to prepare it for the endurance flight segment.
>c) At the end of the two minutes, the clock will start running again
>to record a pit crew time, and will run until the airplane starts
>"first motion" takeoff for its endurance flight. This pit crew time
>is a direct deduction from the flight scores.
>d) There is no extra bonus if the pit crew completes its ground
>preps in less than two minutes.
>
>3. Extra propellers. We have a limited supply of the following
>propellers: 7x4, 8x6, 8x3. The GTAs will hand these out on request,
>one at a time, to avoid needless stockpiling.
>
>4. The batteries will be charged overnight and if time allows, will
>get a top-off peak charge at the flight site just before use.
>
>See you at the flight trials and good luck!
