Address: RC Underground Arena, 8775 Cloudleap Ct, Columbia, MD 21045 (If you use Google Maps, enter "RC Underground Arena" and NOT the address, as it will put you in the parking lot of the shopping mall, rather than the parking lot for the event.)


Site and event rules: 

1. All lipos *must* be charged in a lipo bag, in case of fire

2. Please do NOT walk on the RC car jumps/obstacles.  

3. Do not cross into areas which are taped off.

4. Once you have unloaded, please move your car to the designated parking area, as the venue has extremely limited parking available.  On the day of the event, competitors will be directed to the designated parking area.

5. Follow the black tiles floor from the registration to the pits.  The pit area has a red tiled floor.


Tournament procedures

  1. The least dangerous robot goes in the box first. The most dangerous in the box last.
  2. The most dangerous bot comes out first, if at all possible. Then the least dangerous bot.
  3. If a battery becomes exposed, the match is over. The arena safety officer has final say over this safety issue.
  4. In the pits, keep you bots turned off, weapons safeties on and the wheels off the ground.
  5. We will have someone call next match, and on deck match. We will also try to post the current brackets and next fight within the Discord event channel. We have 20 minutes between matches for any one bot, so towards the end, we will likely be having grudge matches to fill time.
  6. No late hits. If the other bot is disabled, ask before you hit them again. Basically be polite.
  7. Have fun, play safe.


There will be a test box available for use throughout the day (thank you NHRL!) Please use it for any testing.

  • Pits will be INDOORS!!
  • If you want power at your pit space, please bring an extension cord.
  • The entry fee is to be paid in cash.
