Glad to learn it was just humor. I feared I had turned you off the carbon tube wings. Now Wayne will tell you I'm an "engineering type". I hope that isn't a derogatory term.
But I'll take it to mean that if I see flaws and short comings I try to offer work arounds. Please when reading my posts don't think that my showing the limitation of a design I'm saying it is junk or of no value. Well, unless I say that straight out.
As the the wiring loom. I love the common bus bar!
As to wire size that depends on the peak not RMS power draw. As our radios pulse the power down the line this is critical. In the old days of the analog servo 20 ms or 50hz this wasn't too much of a problem. But now with 330 hz systems these peaks can easily stack up onto each other.
So back to your question how many servo will each bus bar be supplying? I think you said you were using Digital servo. If using more that 3 I'd go with the larger wire for the positive and negative leads. So my looms often look like they have 2 large +- wires and 2 to 4 thinner signal wires.
No I'm not trying to help Wayne with his wire sales. But get a run of large gage red and black twisted wire . Also get some thinner wire with a white and orange lead. I separate the large white wire from the red and black one. I also separate the white and orange wire from the lighter wire. I then twist (for noise cancilation reasons) the large red and black wire with the smaller white and orange. I know of no source of multi-gage 4 color wire.
Now the reason I do this isn't to cut down on the all up weight but rather to pull the weight out of the tip. The lighter the wings 9and their tips the better the wing is to signaling where the lift is!
Might I suggest you look at some of the modern 8 gram servo for your ailerons for this very reason. You can see that I'm using the small KST X0-8 for both the flaps and ailerons on my 2kg 3.2 meter 660 watt glider. While I don't think your glider can really benefit from the light weight flap servo I do think it would be a nice upgrade using lighter aileron servos.
Again this has nothing to do with all up weight but rather where the weight is kept. Keep it out of the wings and their tips!
Up and out,
Konrad
