thats a big no no..
i did the same a few years back , and on take of it went into failsafe , and i could just stop it by grabbing the tail....
since then the lead is allways there!.
you can NOT connect anything else then a RX onto a RX bus on the CB anything more can and will collapse the powersupply , this is what happened.
in the manual it states clearly to connect a powerlead between 4 (cortex) and the CB on any free or y-lead on a existing port.
what happened is that your rx port disabled them selfes.. and cb went into failsafe.
next time make sure you connect a jumper lead...
