Did you get the esc to work?

I just got a new sea king 120 says it has switching BEC. I am planning on running 4s and 6s for short runs. How do I connect the esc. My stock esc has a on off switch wired in. New esc has no switch. Do I plug into channel 2 and that's it or de I need a extra batt pack for the receiver now. Not exactly what the discussion is about but thought is was close. I'm pretty new to all this.
Basically how do I hook up new s king 120 for 6s to the receiver. Do I need the extra battery pack. If not how do I turn it of, just in plug it now?.
Any help from the wise ones would be great. Have card to program but need figure out how to hook up to receiver. my boat is a stock miss geico that I'm up grading the esc. It says it has a switching BEC. Don't want to fry my radio. Thx

Brand new 2s 1000mah Turnigy through a Hifei UBEC voltage limiter and yes I do have a T180 Seaking esc that is super reliable to go back to. My boat never plays up with the T180 but everytime I fit a swordfish I have dramas. I thought upgrading to a 240HV I would have no issues. My gut tells me to ditch the swordfish esc and stay with the T180. No-one has answered my original question.... why is the red wire in the RX lead of a 240HV esc ( IS IT TO POWER UP THE ESC WHEN CONNECTED TO THE USB LINKER?) it certainly not needed for any other reason.

For some reason I could not answer this before but, i can now.

The red wire is for the esc to get power from the RX via a RX pack. The power fed by this red wire is for the logic driver cicuit. HENCE, the OPTO-Couple feature. This feature prevents interference between the logic board and the power fets. Wheter it is for the USB linker I have no idea. I've never programmedvia USB. I think I just plug & play...

To the gent's above post of the 120 esc. All you need to do is plug the esc wire into the Rx and as soon as the main packs plug in, you are turned on, so have your TX turned on first.

Some say Bec is fine but, above 4S I tend to use separate U-bec wired to an external switch. This is your call but, if you choose not to use the Bec your red wire needs to be removed from the socket or cut (again your preference). Then you would need a seperate Rx pack and a switch wired into it.

Don't mean to complicate things for you so, if you want to you can use the built in BEC up to 6S as the manufacturer suggests or claims will work. Please read all the manual information in case i missed something.

Two things I noticed about the hk/flysky rx is the failsafe is set to wide open as default ( cost me an Elam) and once they get wet they become extremely unreliable. If that helps, btw the red wire is required to update settings on the esc

Thanks on the failsafe heads up!! I'll go reset that right away!

No wonder my boat came into shore once full tilt!!
