REMOVE THE COVER ON A CHANNEL 2 CRYSTAL FROM A HL RADIO AND YOU WILL FIND IT IS 14 MHZ AND SOME ARE 13 MHZ I HAVE SOME OF THEM AND TRAXXAS CRYSTALS WORK IN HL

i have metioned this to bill at rccommand and he checked some of his and found the same thing so be carefull some channel 2 radios will only use the 14 and 13 mhz crystals
