    Maybe the hinges are "sticky"? Perhaps, the rods are not in the same holes for all the flap sections? Signal getting distorted going through the blue box?

      hinges are not stick and all free movement, the rods are in the same position it is something in the blue box for sure or a wrong connection really can sorted out...Everything is working except flaps that work not simultaneity left wing small flap move with the right wing big flap the others work almost the same on take off position...On the landing position they are more sincronised but as i set to back to 0 position the move differently at different speed ...

        It could also be in the wing board connection. To know for sure, you'd have to take the wing board apart and get at all the flap plugs. Gang them all together with "Y's" and run them on a servo tester to see if they work the same.

        • Has anyone set up differential thrust on their airliner? If so, how effective is it?
          TIA

              Just curious as to what you would gain by using differential thrust?

                I'm curious as well.
                The AL37 has counter rotating engines.

                  Me, too. The big rudder is quite effective on this plane. However, perhaps he wants to do flat spins with a 737 or maybe put giant floats on it and fly it off water and have good rudder authority for water maneuvers.

                  • Or maybe I just want to do it for the sake of doing it.

                      • Can this thing fly inverted?

                        • So, flat spin a 737 - nearly.

                            I don't see why not. It'll roll and loop. Flying inverted is just a loop where you stop looping at the top or a roll where you don't finish the roll right away. But you better be careful or the scale police will come for us.

                              Actually it can quite well.

                                Thats right! Save the rolls and loops for your other jets. This thing looks good when flying scale like. Thats why we customize them. So don't ruin it by flying it inverted! : )

                                  The problem with telling them not to do it, will certainly drive them to do it even more. LOL We will see a hovering 737 I'm sure. As far as I'm concern, "More Power to em", I say go for it. Now for me personally I'm not a particular fan of this sort of flying, but who cares. They bought it, they paid for it, and if they want to hover it, it's totally up to the owner.

                                  To this end, I will say that flying a model helicopter like a real helicopter is the most difficult type of flying, in my opinion. When I see some accomplished model helicopter pilot do all the inverted, ass first, or what ever with the model. I respect what they like. But as a pretty serious real helicopter pilot, I'd pay a thousand dollars to see one of those guys get into a new Jet Ranger and try some of that impressive stuff. LOL

                                        I’m actually sitting here off the A1A in Cape Canaveral waiting for the launch. Flew down here from Scottsdale, Arizona to see it. 50/50 likelihood they’ll light the candle at 1633.
