thanks for the simple solution on the antennae length thats the answer that makes the most sense.
as for using a rx battery separate from the bec i think i will take your advice and not use the additional battery. i had been seeing some jumpiness from the reciever and i think the power wires were possibly causing that interference. i was concerned about how the servos were jumping while the transmitter was turned off (fail safe test) and thought the extra battery may help smooth things out. anyway i was not comfortable with putting this boat in the water until this problem of jumpy servos was completely solved because i was concerned that the fail safe may be compromised.
this is why i keep asking so many questions about electronics, because it pretty much keeps me in 'dry dock" until it is solved.
