every time i plug in charged batts and turn it on it beeps nonstop unless i turn it off. any help

Try to switch throttle TX switch to reverse if it isn't already.

ok has that happend to you b4

edit: the throttle reversing swithch is on the N position. is that the normal position

A lot of the ESCs out there will ask for the Tx to be in R (reverse), especially on the Futaba gear...
I have a couple that will keep on beeping until I hold the throttle down in reverse (past the neutral point) and stop... but that will be your new zero, meaning you have to keep the stick in reverse for neutral. Easy on a 4 channel without return spring.

Did you ever have your SV work before this happened ?
Did something get wet ?
Try to unplug esc from RX does the servo still work ?
Try to plug esc into steering slot on RX and esc and servo into esc slot
Will the servo work now ?

yea my sv27 worked great then one day it didnt work. took it all apart and it still didnt work. when it did work the thr. reversing swith was in the n position just liike now.

edit: i just put the thr. switch is r and now it works. how come it switched on itself. it worked on n now its r???

thanx for helpin me
