As for the reciever pack... I run orion 1600 Ni-Mh packs ... Ive run all day on a charge and had plenty of juice for the main....

For my controller i just went to wal-mart (shame on me) and picked up a pack of energizer 2600mil Ni-Mh Double AA's .... Had them for a year and still going strong. Charge the controller every few race days...
