John Bisset Posted August 6, 2019 Share Posted August 6, 2019 A query on wiring. I have been extending some leads in a couple of my models, to re-position a UBEC. I am also tempted to lengthen the leads from an ESC. However, I don’t have any wire which is as flexible as the wiring typically used on ESCs, or UBECs. Diameter, or more accurately cross sectional is the critical point for power capability but forp flexibility multi stranding? I presume I need multi core copper wire with very fine individual strands. Is that correct? Can anyone advise me what type of wire to ask for and if possible, where I might be able to buy it. I do realise I may need to add a capacitor if I increase the ESC to battery lengths. Adding say 10cm maximum to the ESC to motor run I think I can get away with. Thanks.

PatMc Posted August 6, 2019 Share Posted August 6, 2019 Hobbyking sell various gauges. Hobbywing 40A & 60A ESCs tyhat I have both use 14AWG. Quote Link to comment Share on other sites More sharing options...
Martin Harris - Moderator Posted August 6, 2019 Share Posted August 6, 2019 Silicone covered multi stranded wire is what you need - various examples on this link. Most model shops should hold stocks of suitable wire - or try one of the mail order specialists like 4-Max By the way, extra capacitors aren't needed on the motor side if you extend the cables - just on the battery connection side if you extend past the manufacturer's maximum recommended length.

Cuban8 Posted August 7, 2019 Share Posted August 7, 2019 Like model shops, they're getting a bit thin on the ground, but a good motor car spares/accessories shop usually has a range of cables suitable for our use. My local one is very good for this. Quote Link to comment Share on other sites More sharing options...
Broken Prop Posted August 7, 2019 Share Posted August 7, 2019 Heads up for Component Shop. I have just bought some of their silicone wire and it appears to be of good quality. Very flexible as well. Pete Quote Link to comment Share on other sites More sharing options...
John Bisset Posted August 7, 2019 Author Share Posted August 7, 2019 Thank you , all of you - most useful. This is one of the several things I like about this site - there are so many knowledgeable people prepared to share their information! I had wondered if the 'silicone wire' was what was needed. I shall buy some and try it out. (Annoyed I hadn't thought to check the Max site, Martin. George is very helpful & an interesting chap to talk with - I could have asked when speaking to him the other day!) Cheers, John B Quote Link to comment Share on other sites More sharing options...
Martin McIntosh Posted August 7, 2019 Share Posted August 7, 2019 HK or Component Shop for the wire. Do not even think about extending the battery to ESC wiring. Even with the correct type of capacitors used on my Mosquito an ESC failed on take off on the second flight. Now repaired but not tested in the air with the ESC to motor wires extended instead.
