[NSRCA-discussion] Looking for a pattern plane

Wed May 9 11:48:58 AKDT 2012

Well, it sure has been fun watching all the email fly, innuendos and all.  Maybe Ron just sent the wrong link, because no where in the product description or specs provided does it say that it is a dual regulator.  That is, after all, the information that we have to go by from his original post.  This description implies a switching circuit at the input side to the regulator is employed.  If I was looking for a dual redundant regulator, I would expect the description to say that somewhere.  Or it could be inaccurate since details sometimes get lost in product information when the writer isn’t as familiar with the English language as we might otherwise expect.

      The HobbyKing Regulator switch is an easy and convenient way to add dual power redundancy to your electronics system. Simply use a pair of 7.4v Lipoly batteries and the system will provide dual 5.9v power outputs. The dual outputs can be used for 2 receivers or with a single receiver by using only one power output. In the case of a single output/single receiver configuration the output being used is supplied power by both batteries or a single battery in the case of a battery failure.

      This system provides a stabilized voltage of 5.9v. Perfect for 6v Rx systems. This design enables you to use the latest lightweight Lithium-Polymer cells without exceeding the maximum voltage of 6.0 Volts.

      The Hobbyking Sensor is equipped with LED power-on indicators for both power circuits. If you switch one battery on, the associated green LED glows. When both batteries are active, both LEDs light up.

      The total voltage loss in the HobbyKing Sensor is about .35v which is so low that the volume of waste heat is almost negligible. The maximum continuous current is 5A which means it can easily handle up to 8 servos. However the rated continuous current of 5A does not reflect the capacity of the electronics which can handle much more for short periods, depending on ambient air temperature.

      Do not allow the heat sink to exceed 60 Celsius

      Specs:
      Operating Voltage: 4~9v 
      Power Supply: One or Two 2S 7.4v Lipoly
      Max Load: 5A cont.
      Voltage Loss: 0.35v
      Voltage stabilization: +/- .1v
      Weight: 35g

      Directions.
      You cannot manually switch the current from one battery to the other, this is done automatically within the system. 
      The control functions consist of three push-buttons, two green LED’s and one red LED.
      The buttons are marked SET, I and II.
      The ‘SET’ button is to prepare the system. Holding the SET button in for 2 seconds ‘arms’ both internal switches, this will be shown by the red LED. After you have armed the system, press either or both I, II buttons to activate each battery.
      Press and hold ‘SET’ to switch the system off again.

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?

                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.
