Project Limitations

We’re open to projects of all types, but please keep your designs within these limitations. Your project will NOT be allowed to fly if it does not conform to these limitations.

• Styrofoam enclosure (max. 12x12x12 freedom units)
  • Check with the Apex team in the #apex channel to clear your enclosure!
  • Approval is required before using your box of choice.
  • Pre-approved boxes:
    • https://www.amazon.com/Robin-II-Cooler-Outside-Dimensions/dp/B0CK58Y4DH/ref=sr_1_1_sspa?sr=8-1-spons&sp_csd=d2lkZ2V0TmFtZT1zcF9hdGY
    • https://www.amazon.com/ON17F-Thermo-Chill-Overnite-Containers/dp/B00UZBCTK8/ref=sr_1_7?sr=8-7
    • https://www.amazon.com/BOX-USA-B214C-Insulated-Shipping/dp/B01D2788UG?ref_=ast_sto_dp
• Passes all tests
• Does not interfere with the payload train
  • Does not twist the cord
  • Does not cut the cord (obviously!)
• ¾ lbs weight limit (would hit 103,000 ft)
• Any radio transmissions must not interfere with onboard radio communications used for tracking the balloon (432.XXX MHz)
• We strongly recommend all electronic experiments be powered off Energizer Ultimate Lithium batteries, which are rated to work in -40 deg C temperatures.
• Use of red duct tape around corners.
• Nothing that could create a spark (hydrogen is highly flammable!)
• Nothing that could be potentially hazardous (to both us or the experiments)
• Nothing that could potentially interfere with radar systems!
• Enough space for a ⅜” vinyl tube to pass all the way through the payload box
• Please attach 4 small placards around the sides of the payload box, and one large one on the top.
  • https://docs.google.com/document/d/1_uYP9ImGypeJsM29WLHZIiAecdl6vwzFmmaETyTXAmc/edit?usp=sharing
  • Secure with packaging tape
  • If you do not own a printer, let us know in the #apex channel and we can print it at the launch site!

Your proposal must be approved by the Apex team!
