On Monday morning, anyone who has a missing transponder will be charged $50 to their credit card on file. If the transponder is not returned to NASA SoCal (see Contacts page for address) by the Wednesday after the event, a replacement fee of $400 will be charged.

Also please note that transponders are not rented to HPDE1 and 2 groups as they are not timed but are REQUIRED in HPDE4/TT. Thank you for your understanding and cooperation.
