- How to Extend ESC Wires Correctly
The video discusses the correct (and easiest) way to extend the wires on your electronic speed control (ESC).
Given the particular setup of your RC model airplane, boat, etc., you may have the need to extend the wires connecting your motor to the electronic speed control (ESC). This could be due to a need to locate a battery further aft for center of gravity considerations, a unique motor pylon, etc.
The more difficult method is to lengthen the two wires to the battery. Due to technical reasons of how the ESC communicates to the brushless motor, you will need to add capacitors if you extend the battery wires.
A much simpler, and in my view correct way to extend the wire length is to simply extend the three wires from the ESC to the motor. This can be done with no damage to the ESC and no need to add capacitors. I have done this for wire lengths up to 12 inches.
One further tip to reduce interference is to twist the three wires from the ESC to the motor, with about three twists per inch required.

Very interesting Tim ! As a beginner, it is REALLY appreciated. Long life to your channel.
1983: Thanks for checking in and your kind words! Tim
Thank you Tim for teaching us beginner the do's and don'ts of RC , great video. Take care and stay safe.
Javier: You are very welcome! Tim
I personally dont put heat shrink on until the bullets are connected to each other I normally leave them that way but if I need to separate them I just run a x-acto around the bullet to cut the shrink and then pull apart.
FFF: Yes, you can certainly follow this technique. Works well. Tim
Thanks Tim, you have saved me from another potential screwup!
Robert: Hey, thanks for checking in! Tim
Good vid Tim, never knew that about the battery side extension.
Dave: Copy all, thanks for checking in again! Tim
Should have no metal of the bullets exposed when connected soo many speed controllers have been cooked from the motor wires shorting out on exposed bullets
FFF: Fully correct. The always feared "magic smoke" when a component is accidentally shorted out. Tim
Very good information. Subscribed.
RC: Awesome, thank you! Tim
Very helpful thank you.
Paul: You're welcome! Tim
It really don’t matter with the Low power stuff. You can extend the battery or motor how ever long you want. I have extended the battery wires up to two feel on 8s (30v) 110a no problem. If your running high voltage or high amps different story but for the small little stuff doesn’t matter whatsoever.
👍🏻 Tim
Very helpful Tim. What wasnt clear was when you talked about adding a capacitor to the battery wires. What does that look like? I couldn't really see what you did.
Tim: You would add the cylindrical capacitors if extending the wires on the battery side. This is hard to do as you will have to make calculations on the size of the ESC, batteries and added wire length. If you know how to do this, there are pre-made capacitor banks that can work. My point is to simply avoid this hassle and just extend the wires on the motor side, no capacitors or computations needed! Tim
@@grahambate3384 Graham: Yes, you are correct with the need to add capacitors if lengthening the battery wires. For most folks, to include myself, a lot easier to not worry about the capacitor issue and simply lengthen the motor wires. Tim
Muito bom.
👍🇧🇷🇧🇷🇧🇷
Thanks! Tim
Weird because I have always seen it and have it done the other way around. Battery leads going from the nose of the plane out to the ESCs and motors on the wings with no problems no added anything but wire. Up to 2 ft added wire on each wing motor pod from a set of batteries in the fuselage. Never seen it done the other way around with the ESC in the fuselage and the 3 motor control lines run out to the motors.
Ron: I think the various ESC and number of lipo cells affect the installation as well. Tim
I need to order wire to solder to my 3 esc leads...i like silcone coated wire but what size/ gauge is normal for a 40 amp esc? 16? Thanks
No idea; maybe try a Google search? Tim
@@TimMcKay56 i ordered 16gauge..seems about right
@@roadstar499 😊👍🏻
Can you extend the wires on your battery by using connectors. Then connect to esc. The results would be the same as extending the wires on the esc. ( the battery wires would be longer) But you wouldn't have done anything to the wires on the esc.
William: I do not think this will work. The electrons just see a distance to go over a wire. If there is a connector, does not make any difference. So do not mess with the wire length from ESC to battery, but OK to extend the wires from ESC to the motor. Tim
@@TimMcKay56 Thankyou very much and I will listen to your advice.
But what can you do if you need to move the battery all to the back of the boat for weight distribution.
@@williamhendricks2078 Well, may have to add additional weight. Tim
