[NSRCA-discussion] Looking for a pattern plane

All I gotta say is, I buy American whenever possible<g>. Especially in this case.

Ron,
Did you use the same input plug for both lipos? If so, all I can say is that it only costs $14. If not, there may be some frontend circuitry in there that somehow establishes a secondary and a primary battery input to the single regulator.

When I did the test, only one lipo at a time was hooked up to the separate switch/regulator inputs.  The output voltages were different, which I attributed to tolerances in two regulators within the device.  If there really is only one regulator in the switch/regulator, I cannot understand why there's a difference in output voltages.

You are still only reading the regulator output from one of the lipos and both outputs would have to be the same. 
Ed is saying the single regulator dual outputs are not independent as they would be if you used two tech-aero or jaccio regulators.
Sounds like a good system to have on a smaller cheaper aircraft than our 2 meter pattern planes. Gives you redundant batteries but not redundant power systems. You are now reliant on a single point of failure 14 dollar regulator.

Hmmmm.  I wonder why I measure different voltages when I switch on the two 2S lipo batteries at different times.  If it had a single regulator, I would think the output voltage would be the same, no matter which battery was chosen.

It’s actually a dual output single regulator that can switch between two power sources.  It provides two leads from the same internal source, so only the battery side of things has any redundancy.

Ron - It is a dual regulator/switch which allows you to hook up two lipo batteries and have them separately regulated to 5.9 volts and use one or both of the outputs.  Look here:

I sell them for under $20.

Hey Ron, rusty and old, but I'm going to give it another try. Emory Schroeter told me about a dual regulator for the receiver pack that you are selling, what's the scoop?

Hey Ron:  Buy it and our old fingers can duke it out again.  I look forward to having you on the contest trail again.

Hey Ron I have a Ca Models Visa for sale ready to fly and would be more than happy to drive it down to your place.

I'm looking for a used pattern plane. It's been about 10 years since my last contest,   and I want to give these old fingers another chance. I'm looking for a fixed gear 2m design, and plan to do an electric setup. I can convert a methanol burner if necessary.  I live in Nashville,tn., avoiding shipping would be good.

Thanks...Ron
