Help with making my own servo extension, question on the wire...

[orthobird]

I am needing to make servo extensions. I have done this before, and was wondering what those who have like to use?

questions:

1. for HV system, (i will be using at least 55" length from rx to tail servos.)

2. 22 gauge vs 20 gauge (i believe 24 is out of question)?

3. spiral vs straight?


if anyone knows, please let me know what has worked best for you, and where i can get it..


thank you

Maxx Products Inc. or MPI sells a nice crimp tool and the male and female connector and housings. 22awg wire in various lengths. With 2.4 flat wire is non issue. Spiral if you like the look and handling. At almost 5 feet length 22awg is fine as far as current. Signal however on some older Futaba 2.4 receivers is 3 volts and coupled with the voltage drop from that long length my cause an issue on some servos analog or digital. That is one reason why I use the Power Expanders on big planes with long leads. It supplies a steady 5 volt signal that is buffered and filtered.

i am also using a power distribution system, but you believe 22 is good enough, and fat is good too. what about where do you buy yours from? i am only interested in the wire. I have everything else. Thank you!!

Hanson Hobbies is where I get my ingredients to make my own straight 20ga servo leads, plus tools, male and female pins and multi pin connector housings,,, http://www.hansenhobbies.com/products/connectors/

Or, check out TaildraggerRC for pre-made long servo leads as well,,, http://www.taildraggerrc.com/

I don't by my wire I just take it from my buddies shop!lol . But really I normally wait and pick up wire and shop things at Perry GA. and it has been awhile. You can find some good discounts from bulk vendors at Perry.
As far as 22awg wire it would take a good 25' before adding to the overall load being placed on it. Even if you had four servos drawing 2 amps each the 22awg would handle it. May get warm but not hot and melt the insulation.

I really like the powerbox wire. Thin high temp insulation. The weight is in the wire... Try some and you wont go back.

Ive use 22ga flat and twisted. Extensions were upwards of 60". Never an issue.

Obviously, the larger the wire, the lesser the voltage drop. Your limiting factor is the servo plug, as far as current capabilities.

Just make sure that your pins are copper coated. I have used connectors and pins from many places. I found no difference in them.

was going to say Hansen Hobbies for crimping tools (blue handles) and supplies for custom wires. i bought a crimping tool (green handles) somewhere else and it was crap.
