Title: Futaba mode change on 8FG/12FG . Calibration ? Post by: gauravag on April 24, 2010, 10:57:27 AM Hi all,
I was asked to change the mode - From Mode 2 to Mode 1 on a Futaba 8FG radio the other day. Before opening the radio, i tried to search the internet for resources and got mixed opinions. Some said that it was straightforward to do , ie open the case, change the springs, and go back to the software and change the mode. Others said that it would need calibration of sticks. Now I am not sure what this means. Looks like the sticks on these radios are supported by quad bearings. Does this mean that calibration would be needed when we switch modes ? Please share your experiences so I can help this flier out. Thanks Gaurav Title: Re: Futaba mode change on 8FG/12FG . Calibration ? Post by: anwar on April 24, 2010, 11:20:48 AM I am confused. If you set the subtrims and end-points to zero, check in the servo monitor if all channels show -100 and +100 at the maximum stick deflections, then a mode change alone should not change anything.
I have noticed that the center stick position, as marked physically using small white lines on the side of the stick holder case, is a bit off on my 12FG as compared to what shows in the servo monitor. But I have seen the same on many other TXs too. As long as the maximum and minimum are 100 on each side, you should not have anything to worry about. It should not be an issue while flying that the center (when you get servo centering) is off by 0.1mm or 0.2mm, something that can be taken care of using trim/sub-trim. |
