Can anyone advise me as to appropriate wire and guage for the

flap motor wiring?  Looks like four conductors are required. Do they all

need to be heavy enough for the motor draw, or just two of them? Would it be

criminal to use trailer wiring cable?

If this is for an XL then 6-B-20 (Date 06/03) shows that all 4 wires carry

the full current. I've measure a steady-state current draw of about 4 amps.

For that current over a rough length of 7-10 feet 18 gauge would be a

suitable size:

Generally Tefzel wire is recommended in aircraft.

Craig,

            Thanks for the input on the flap wiring. That will get me

started.

Lynn, one thing that was not explained in detail about

the wire type is the reason why you should use tefzel

wiring.  



In the event of an electrical fire or meltdown, PVC

insulated automotive wire gives off a very toxic smoke

that can quickly incapacitate the pilot in an enclosed

cockpit.  Tefzel, on the other hand, while giving off

an annoying smoke, should not be seriously harmful.  



The trailer wiring you mentioned would most likely be

PVC insulated.



A couple of good sources of information on aircraft

wiring are the aeroelectric connection website.  Jon

Croke has a good beginners DVD on wiring on the

homebuilthelp.com website.  Also, Greg Richter of Blue

Mountain Avionics has a good beginners guide to

electrical systems but it is not easy to find on his

website.  I couldn't find it the last time I looked.



Hope this info helps.

Tefzel is also a lot more nick-resistant.
