Swordfish ESC's

[Krusher]

I just bought the Swordfish 120 on Wednesday so I don't need any more info on the SeaKing comparison.

Earlier, m4a1usr recommended that if you have an auto timing setting, which we do, leaving the timing alone. That was my plan.

Has anyone tried a switching frequency on these ESCs other than the default 8kHz? I see we can pick 12 and 16 as well.

I'm going to be running 6S on a Neu 1415/1.5Y (1500kV, 4-pole) if that makes a difference. My goal is not maximum speed, but to keep everything running the coolest.

Thanks.

Proram card issues

Steven, having trouble getting 240V Swordfish to accept program from the program card. Have 6.0v pack connected to the two bare power wires on the harness, red/black/white connected according to polarity on back of program card...other end of harness connected to ESC. Leaving ESC off, turning on 6.0v power source and I get the red light on the program card. Then turn on the ESC, get a green light on the bottom of ESC. Press the "transmit" button on program card and nothing happens. No motor or lipos connected to the ESC (assuming I don't need that). The instructions that came with the card say the red light should blink twice when programming complete. Any suggestions?

BTW I checked and my battery pack is delivering right at 6.0v so I don't think that's the problem.

Got it to program, the polarity is flip flopped in the Y harness, causing the card to not program. When I plug the harness into the ESC throttle control backwards, I'm able to get it to program. On the wires, for me that means Brown to White, Red to Red, and Orange to Black.

What radio are you using?

Mine is the same way. If you have a SF240 just pay attention to the wires rather than the plug. I'm not sure if all the plugs are consistantly backwards or if its just some so best bet is to go by the wires.

Are you saying the socket in the program card is wired backwards? Or do they provide you with a Y-harness that's backwards?

Its the y-harness. I plug the esc into my receiver as I would any other esc.

[sailr]

I see. I don't have one of their esc's so I guess they send you a Y harness with it? I've always plugged the esc directly into the program card on all the other brands. No need to have it plugged into the receiver usually. I guess the Swordfish is different.

Solved my problem above, the 12 year old Schultz took out a phase in the UL1 motor when it failed. Changed motor and ran it today all's well!!

[Jeff]

I think you have that reversed. When the motor failed it took out the schultz.

[keithbradley]

I may not have worded that clearly. There is no need to use a receiver to program it, I just meant the plug on the esc is wired correctly.When I put it in the boat and run it, I dont plug it into the esc upside down.

Swordfish stand-alone programmer

I just bought the standalone programmer for the SF ESC's. It works great on my 120, but I cant get it to work on the 240. It shows a y-harness in the directions like the one that comes with th eusb link, except it has an extra set of wires for teh rx pack to plug into...so it's a total of 4 sets of wires instead of 3 like teh usb link version.

How do you get this to work? Steve do you sell a harness for this?

Keith I'm a bit confused. There isnt a separate harness. We might have to contact Hifei about this.

[keithbradley]

I got it to work with the y-harness from my usb linker. (It does show a harness like I described in the instructions, but I guess its not needed after all)

On your site it says to use a 4AA rx pack, so I tried one instead of the nimh 5 cell rx pack I was trying to use with it, and it worked. I checked and double checked the wires on the rx pack and esc...maybe it's just possible the two pin connector on the 4AA style packs makes better connection with the programmer?
I suppose it's also possible that I turned the ESC on AFTER I plugged it in when I tried it before. I noticed even when using the 4AA pack if I plug it in and then turn the ESC on, nothing happens. It has to be on when you plug in the battery.

Controller on 240HV have a 4.5-5.5V tolerance.. outside that range and it will not function... eg 5 cells wont work.

The SF240HV has no BEC..
The programmer gains power with 3plug wiring harness from BEC enabled ESCs.. it needs external power for the SF240HV... thus the 4 connector lead

Assume you plugged 4cells direct to programmer somehow to achieve successful program with 3 plug leads... ??

details ?
