Two resistors, 4.7 ohms each, in series, will be 9.4 ohms and will actually put slightly more load on the PS than a single 10 ohm resistor. They will work fine.

The two 5 watt resistors, being equal resistance, will dissipate the power equally, so the equivalent power rating would be 10 watts. However, at 5 volts the actual power disspated should be only 2.6 watts. FWIW, a 10 ohm resistor across a 5v supply would be 2.5 watts. A smaller 10 ohm resistor rated at 5 watts would work fine.

So, use the 4.7 ohm resistors, they should work fine.

Warren this is not a model power supply. This is a computer power supply that has been modified for model power supply use. Here is a link with a part number http://www.tigerdirect.com/applicati...&Sku=A107-2000

Glad to hear it Warren. I am finishing up my BBW Yak right now. Waiting for some exhaust parts to come in that will bring the cans closer together and 8711's then we are in the air with #2.

Mike, Just wanted to pipe up and tell you all what a great thread this is. My dad tried this years ago and couldn't get it to work, back then the power was too little, not enough Amps he said - so he stayed with his little field 12V batts. Anyway, I sent him this thread to say the least. Also, I went on eBay and found the exact same Apevia 500W PS that you used, got it for $15. I'm going to Radio Shack this AM...

Mike, thanks for a great PS project.

i worry a bit about using the 5 volt rail for receivers. how well regulated is it, and how well filtered (DC) is it? a bit of a voltage spike could damage a receiver, unnoticeably at first...
