I do a lot of fast charging and to balance my batteries I cycle both the Tx and Rx and have always been able to cycle my 10X thru the charge port. Some of the early Futaba radio's ie: 8UA you had to remove the battery to fast charge and cycle, but now even the 9-C can be fast charged and cycle thru the port I believe. Dennis
Yes, the Futaba 9C can be cycled through the charge port because Futaba uses a poliswitch instead of a diode. On lesser Futaba transmitters you do have a diode.
Your choices are jumping the diode (and voiding your warranty) or sending the TX into Futaba to have them put in a poliswitch ($20). You can also buy a poliswitch from Futaba.
