Hi Guys,
         this is my first post in RCIndia,I am not new to FMS, I have a problem with the interface connection - I am using flysky 6 ch radio.However, when I try to calibrate it everything functions OK except the aileron (No.4 channel), which jitters about in the centre. There is no proportional control and when the aileron stick is moved the bargraph just jumps suddenly from bottom to top.But ,when i calibrated it on t6 config ,everything is ok.
I think that the controller is OK as it works perfectly with t6config and t6sim.anyone had a similar problem?

Py.. reinstall the software.. please check the multi Aux pin connection for any loose contact..  make sure the cord is working, by connecting with an other radio set..  open the back cover and make sure, the universal joint of joy stick is propperly connected to the relevent potentio meter..  check for any dry solder points in Tx PCB..  check and make sure the potentio meter is properly working, with multimeter, in Ohms range, by disconnecting the three wires from potentio meter, while marking the wire colour codes.. the resistance of potentiometer must show gradually, as you turn it from one end to other end, while, holding one probe of multi meter, on the centre point of the potentio meter, while the other one in any one of the extreme leads of potentio meter.. repeat for second side.. if reading come erratic, clean the potentio meter with cleaning liquid, or replace with a new same one.. the reading must be according to the value of potentio meter, most of the time is about 5 Kilo Ohms.. soldering and de soldering must be carried out with a unplugged soldering iron, after heating it maximum, to avoid any internal damage of components by current leak from soldering iron.. have a nice calibration..

thank you for the reply sir  but i did not understand it is working good with T6config,but not with fms.anyway first i will try to open it and i will recheck it.
