Default Stick centering Problem on Futaba 8FG Super

Hi,

I suddenly started having this very wierd problem with my Futaba 8FG , upgraded to the latest firmware.

When i switch on, and go to the Servo menu, I get random values on the Elevator stick. When i move the stick it seems to work OK, but the value gets stuck somewhere again. Mechanically i dont find any problem wit hthe stick movement.

It somehow seems to loose the centering ability , while many times it works perfectly fine. Its just random, but is way scary when I think what it can cause if a plane is up there and this acts up .

Any help on what this might be related to ?


I can post a video, if you think that might help.

Thanks

OK i have been playing around and observed the following. The gimbal on my radio is connected to the main board via a set of 4 wires with connectors on each end.
The conenctors were tight, but it seems as if there is some resistancei n the contact. I took the wires out, sprayed with some isopropyl alcohol and put them back in after drying and bingo the sticks weorked fine ! there seems to be no centering problem now.

I opened a 8FG Super which i had lying around, and noted that the wires on this were soldered instead of the connectors. So are these connectors a known failure point ?

That's a running change Futaba made in the 8FG production.

You just need to inspect the connectors from time-to-time and keep them clean.
