      If you use gyro outputs 4 and 5 on the super 4 gyro connected to the main wing ailerons does left wing go to 4 and right wing go to 5 and have you had to reverse one of the wing servos so that before you connect to the gyro you have one normal servo and one reversed servo ? Also if you have tailerons and ailerons working together does this not make the plane very roll sensitive or do you dumb down the aileron rates to compensate ?
      No doubt I am missing something here

        It isn't over sensitive in roll.

        The A3S4 is programmable with respect to servo response direction on outputs 4 and 5, so there's no need for reverse servos.

          Thanks, time for me to buy an A3S4

            Thanks, time for me to buy an A3S4 I should end up with this :-

            ia10b RX setup with radiolink Tx as follows :-
            Channel 1 Left taileron Y`d to left (up/down )vt servo to gyro out 1
            Channel 2 Right taileron Y`d to right (up/down)vt servo to gyro out 2
            Channel 3 Throttle/motor
            Channel 4 rudders Y`d to central left to right vt servo to gyro out 3
            Channel 5 Landing gear
            Channel 6 Flaps( I have the inboard flaps now so I might as well have the option to use them with a touch of down elevator mix as a flight mode.
            Channel 7 slider gain switch connected to A2-E2-gain port on gyro.
            Channel 8 gyro on/off/autobalance 3 position switch. via serial/RX/M port on gyro
            Channel 9 left aileron to gyro out 4
            Channel 10 right aileron to gyro out 5
            B/YCC Bind plug and power in from external BEC

                Already downloaded and read a few times. The gyro and programming card should arrive in a couple of weeks. New tx arrived today, fitted lipo, done initial setup, sticks calibration, reduced spring tension on gimbals, reduced stick length a bit to suit my thumbs. So far so good ! Working my way through tutorials by RC Video Reviews then I will bind and set up my Avanti as a practice plane and have a few flights before I have a go at the SU35. ​

                  ok so if I use delta mix on the programming card, connect left elevator to out1 on the gyro, right elevator to out2 on the gyro, rudder to out 3 on the gyro and my main wing ailerons which I currently have on a Y lead to out4 on the gyro then I dont see the need for out 5. Also if I did separate the main wing servos so I can use out 4 and out 5 then what stops the gyro acting as pitch on the main wing ?

                    Suggest you read the manual.

                      Well the good news is I think the penny has dropped on the A3 super4, all will be revealed in a few days time when and if it arrives. On the other hand I have sent the Radio Master TX16s back to the supplier, I just cannot live with the weight, balance, grip and feel of the unit and I cannot get my thumbs to lay where I want them with the thickness of the unit. The A3super4 will however allow me to setup tailerons and the mixes I want on my existing radio so I will settle for that for now.

                        I still think you would have liked the X20S a lot more.

                          Maybe next year, in the meantime I have achieved what I want out of my existing radio for all my models now including my SU35 with the following setup :-

                          Current setup of SU35 with Flysky FSi6X tx, IA10B pwm rx and Hobby Eagle A3 super 4 gyro using programme card
                          designated as flying wing.
                          Channel 1 Left taileron servo (aileron in radio tx)Y`d to left (up/down )vt servo to gyro out 1

                          Channel 2 Right taileron servo (elevator in radio tx) Y`d to right (up/down)vt servo to gyro out 2
                          Channel 3 Throttle/motor( throttle in radio tx )
                          Channel 4 rudder servos( rudder in radio tx) Y`d to central left to right vt servo to gyro out 3
                          Channel 5 Landing gear ( assigned to a chosen switch) 1% down elevator mix with gear down
                          Channel 6 Flaps( assigned to a chosen 3 position switch). I have the inboard flaps now so I might as well have the option to use them with a touch of down elevator mix (2%)
                          Channel 7 Gyro main gain to roll dial on tx
                          Channel 8 gyro on/off/autobalance lead( flight mode lead )connected to serial/RX/M port on gyro
                          (assigned to chosen 3 way switch)
                          Channel 9 left main wing aileron servo to gyro out 4 (set as ail in programme card) No switch assigned
                          Channel 10 right main wing aileron servo to gyro out 5 (set as ail in programme card) No switch assigned
                          B/YCC Bindport on rx takes power in from external BEC​.( 6 to 10 amp ztw set to 5,5v output powered with 500mah 2s lipo consuming 100mah/3 min flight )

                          Gyro A E R port with supplied 3 way lead (yellow, red, brown leads) to Ch1,2, 4 slots respectively on the receiver.
                          Gyro A2- E2- G port with supplied 3 way lead (yellow, red, brown leads) to Ch 9,10, 7 slots respectively on the receiver.


                          A bit of juggling with servo reverse was required in the radio and programme card. I now just need some half decent weather for my first flight with tailerons

                          • I need a little help. I managed to break a few blades on the right side EDF. Fortunately, nothing else was damaged. There are 2 replacement fans on the MotionRC site. 1 is reverse and the other normal. I'm assuming the normal is clock wise rotation and reverse is counter clockwise rotation. Is this correct? If yes, which side is reverse and normal?

                              This is easy to figure out for yourself. Take a look at the pictures of the fans on the "spare parts" list at MotionRC. Now take a look at the one of yours that's broken. Pick the one that has the blades going in the same direction.

                                Thanks Xviper. That was easy enough. Simple common sense goes a long way :)

                                  That is usually the best way. Occasionally, especially when I don't know if you got the plane second hand or not, the previous owner may have swapped the fans side to side. I've even seen the odd time (not on this plane), when the fans were installed on the wrong sides at the factory. Now you can't say if you have a left or right one, forward or reverse, although most reverse fans/props turn counter-clock when viewed from the rear.

                                  • Tuning in after a long while!

                                    I use tailerons + flaperons. They aren't needed but I still like to use them (flaperons) for the scale factor. Also help take-off faster, and that's a big plus to limit FOD on my gravel runway.

                                    My 4th SU-35 just passed the 450 flights too, w00t!
