    To be clear, there's a master gain and each channels gain can be raised or lowered via the software. The gain channel still controls all three gains at the same time.

      Just ordered a P.B. IGyro 3E from Chief this morning. Will be adding it to my Pegasus once I get it. Anyone with setup tips?

        I don't know...I hear Turbine Powered Turbo Porters go pretty fast!

          Make sure you mount it flat

          Other than that just read my review on their web site and if you have any questions just fire away

            "mount it flat" means parallel to the thrust line of the airplane, I take it? Thanks

              And parallel to the wings. There is a piece in the AMA mag about the iGyro, that says to orient the iGyro 3e with the leads from RX to gyro forward and the servo leads to the rear, for the gyros to be aligned with the factory set up. But this is all the instructions show!



              Was that what you discovered Andrew?

                That article is a little unclear because he's talking about both the Cortex and the iGyro and it kind of ran together.

                With the iGyro it doesn't matter because you set the direction that the servo corrects with the button during the setup sequence.

                With the Cortex you need the stock orientation unless you configure it with the software.

                Yes, flat with the thrust line, you want the gyro perpendicular to the axes it's controlling. The wives tale of it needing to be at or near the CG is utter nonsense, it can be mounted to a pole on the wingtip and as long as it's flat it will work the same.

                  Maybe he was confused, as the paragraph starts by saying...."The installation of the iGyro 3e is pretty straightforward......" thats when he talks about which end to place forward....which as you and the instructions have pointed out is not relevant. He does say that the "Cortex installation is similar, but the orientation is not critical...."

                  I am still debating whether to get either the USB plug or the Bluetooth accessory. I realized last week, that there are less outputs than inputs and the main reason I wanted one was to see if there was a way to have output for two rudder servos. Unless you can turn the USB port into a second rudder servo output. Also, the spot I will place mine may be hard to get to, to reach the button, if one of the outputs is reversed.....so being able to change that with my phone would be a lot easier than trying to reach the button and see what lights are flashing.

                  Also there is a channel on the input side that says Misc.....not sure what that is for?!?!

                  PS:In the same issue of Model Aviation referenced above, there is a great review of the Sebart Robin and Blanik by our very own Andrew Griffith

                    The limitation of the IGyro is the channels are hard wired, and the MISC and USB ports can't be used for outputs. So you're stuck with 2 aileron, 2 elevator, and 1 rudder output.

                      I just confirmed that you can reverse a gyros compensation via the BlueCom Adapter, as long as the iGyro 3e is running VO2 software. If it does not have VO2 you can update it with the BluCom Adapter. You can also change the orientation of the iGyro by 90 degrees using the BlueCom Adapter.

                        Is there a concern about vibration to the iGYRO? I made a flat plate mount for the gyro, and will use the double sided tape, but wonder if I should rubber mount the plate in the fuse--or just glue it in. Does it make a difference on a gas twin powered airplane?

                          I use 3M VHB tape. Mounting in an area of least vibration is best to prevent precession but you don't want the mounting "squishy"

                            Just want to inform you all that we have in stock the Powerbox Igyro 3e, including the USB download cable or the user friendly wireless adapter unit for Android and Apple!

                              I've installed the iGyro 3E in my Pegasus, and have a problem. I think I know what to do to fix the issue, but thought I'd better ask an expert before I make things worse? The Peggy has two elevator servos, both mounted in the tail. As normal, I have one reversed so they go up and down together--which they do. However, the gyro drives one up and the other down when I raise and lower the tail of the airplane on the bench. I take it I can use the "button" on the gyro to reverse the effect of just the one servo, and leave the other one alone??? I just figure out which one is correct, and reverse the other? The rudder appears to be moving in the correct direction, but not yet sure the ailerons are doing much of anything. Also, the amount of rudder and elevator deflection appears to be a lot less than I've seen on a couple videos on the gyro, and that is with full slider movement to 100 and -100. Any thoughts or suggestions would be appreciated.

                                Well, I spent a couple hours in the shop today, and the gryo seems to be working perfectly. Not had it in the air yet, but will soon.
