Hi Folks,
I have a scale bouy tender and I am installing a Bow Thruster. I have a Reversible HiTec EZX-R speed controller I am planning on using. This is how I think it should be connected.

Battery feed from speed controller to the batteries. I will have to make a Y connector so both controllers get connected to power

Reciever connector to desired channel

Output to the motor on the Bow Thruster.

[&:]NOW?????? I do not need the 2nd speed controller to act as a BEC so do I cut the red wire on the wire going to the reciever

PLEASE HELP so I dont blow somthing

Typically there is a switch on the ESC that turn on the BEC to the reciever. I cut the switch off and solder a deans plug on the cut end. (just in case you want to put the switch back) If the switch is not on, the BEC will not function.

Since this "second" speed control will not have a BEC functioning, that ESC will still need the red wire to recieve power from the receiver.

i agree with cutting the switch off and attaching a micro sized connector on the end so you can reattach it later if you need or want to,,,but i have a question,,,,why use a reversible esc when all you need is a dual pole dual throw switch and a motor and a battery controlled from the receiver,,,a bow thruster is inherantly less powerfull than a forward/reverse screw and even the smallest of power applied to the thruster is about the same as twitching the thruster with a dpst switch???? thomas

Thats a good question and point Tom. the reason is that I already have the speed controller and at this point I believe it will be easier then connecting a switch to a servo.

Thanks

I used a reversable ESC on my bow thruster in my MR. Darby tug. I think it works great since it gives me fully proportional control rather than just On and Off in a switch. To me, that equals better control.

Just one mans opinion.

hey guys
i do agree that an esc would give proprtional control but an esc is usually less proportional in reverse than in forward power that was why i had suggested the switches instead,,,a mechanical servo operated speed control like the ones from tamiya or kyosho are proportional forward and reverse,,,,but if the esc you have is truely proportional forward and reverse,ie:full - zero throttle,then by all means use it,,,i have several esc's that are proportional but they have built in brake or reverse delay so when you hit them in reverse you get a surge of power for braking or you get dead stick with the delay type then proportional power applied while forward is fine,,,i have used the mechanical sc's and the swtich set-up and have better success with both,,,,,these are the reasons i spoke up about the use of the esc set-up for something like a bow thruster where you want absolute power at any stick angle
