Hobbyking SS Series 25-30A ESC

First of all I'll just make sure I understand how you connected these.

You paralleled the red and black wires to the battery right?

Then you ran the three motor wires from one ESC to one of the motors and the three motor wires from the other ESC to the other motor, right?

What did you do with the servo/throttle leads?

Because both ESCs have BECs in them, you can't just use a Y-lead and plug them into your receiver -- because the BECs (depending on their design) may fight each other and overheat.

You should remove the red wire from the servo-lead of *one* of the ESCs. This will mean that one ESC will have the signal and the negative wire connecting to the receiver and the other will have all three.

Something else it might be important.

I had to use extender wire for the motors lead but i didn't used silicon

wire like one sold at hobbyking.

I used 3mm wire, from a local store.

I am not sure about the specifications, resistant etc, of the wire but i

now it can manage a lot of current.

More than 30 Amp for sure

Yes i test them with the props on. I will try without the prop's and i will post the results

Originally posted by airwave you could pull the props and check,if the motor/motors are bad it will heat up with no load/prop.

They will heat up even if they are OK. All motors have losses, and these losses produce heat. Multiply the noload current with voltage, and the wattage you get has to end up as heat, since there is no work done by the spinning shaft. Many motor manufactures warns against running them for more than a few seconds without any load.

the sugested props can be for 2 cell or 3 cell they can run ~7.4/11.1 volts,the load at 7.4 may take a 8x?? the load at 11.1 will be a smaller prop.you may allso wish to make sure you were shiped the 1300 KV
there is the 2000 KV and would make a big change in prop size.
