    Jim, Rick,
    Today I will remove the Smart Fly boards and receiver and see what I can find. With the two boards in the nose, getting them out will not be simple. I can't imagine corrosion of copper being at the heart of the problem. Our average relative humidity runs around 12%, and Tucson's is about the same. We will see.

      Humidity isn't the problem... it's the drooling over the new bird! lol

    ARUP, No drooling on my part, at least not yet. At first I was a bit terrified that the glider was intact and not banged up from the shipment, and damaged crate. That has gone to "hangover" like state because I can't get it to function properly.
    NEW QUESTION--- The info sheet that comes with the new Futaba S-9156 servos states "Ni-Cd use only" but the specs for the speed and torque are rated at 6.0V. I can't recall ever seeing something like this on any servo. Ofcourse, I'm not using NiCds, but instead two 7.4V 5200mah Fromeco LiIon batteries, regulated by a Smart Fly Turbo regulator. Anyone know what Futaba is concerned about?

      Well, my wife and I have been relaxing on the Oregon coast for the last several days. Mr Hempel has sent a new set of aileron servo extensions for the KA-6, and I should have them Monday when the mail is delivered (very nice man!). I'll replace the aileron extensions, as well as try the servos plugged directly into the Power Board, and see if they work then. Guys, thanks for the continued help and support.

        As mentioned earlier some servos (even though they give 6 V specs) are not happy above 6. Do you have a 4 cell Ni-Cd pack of any capacity? If so I would suggest you run a test by plugging the battery directly into the receiver and the suspect servos directly in it as well. By doing that you will eliminate any other possibility, except TX and RX. Do the right side servos work OK? If so an other option is to plug the suspect servos into the other wing's outputs.

        Also, looking at the Smart Fly web site they have a download of the PDF instruction manual. It states that as delivered the Turbo Regulator is set to approximately 6.6 V output. The instructions to reset it are somewhat involved and it's best that one reads it and look at the drawing of where/how to perform the procedure. I've attached the link to the page where the PDF file is located below. Just click on the "Downloads" tab and then the "Download" text under the "Link" column to download the file.

        I tried to actually attached the PDF file to this, but I could not determine how to do it. It would not accept the link as valid. Maybe one of the guys here can help, but I'm not sure if this site will allow PDF's as attachments. If you would like to PM me I could e-mail you the PDF file.
        The Smart-Fly TurboReg is ideal for aircraft with engines larger 100cc size.  All power input and output connectors are Deans Ultra Plugs to handle the high currents the TurboReg is capable of.  The unit is will handle 17.5A continuous current but can handle peak currents in excess of 35A.
