Futaba GY611 and JR 9303
I am using a JR 9303 radio, 649 receiver, and a GY611 on my Raptor 90. I have RX.Aux plugged into Aux2 on the receiver and RX.1-4 plugged into Rudd.
I have a question regarding remote gain. I just upgrade to the 611 from my 501 and the 501 displayed the same characteristics.
I have the 9303 set up for Auto under Gyro Sens. For now, let's just deal with POS. 1. If I set POS 1 to 0 my gain on the gyro is 83% (Normal), 52 on the radio is 0% on the Gyro, and 100 on the radio is 76% AVCS on the Gyro. This all makes sense but why doesn't my gain go to 100% Normal with 0 on the radio and 100% AVCS with 100 on the radio? Like I said, my 501 did nearly the same thing so I am assuming it's something in my radio setup I am missing.
It's not that big of a deal but I just want to know why the relationship is not linear.
TIA,
Joe

The total pulse width that the gyro sees includes the wiggle room to add to your servo throw by going over 100 on the end points. So 100 percent of the servo pulse width is 140 to 140 on Futaba, I'm not sure what JR tops out at but its the same principle.

RE: Futaba GY611 and JR 9303
Your servo position (or in this case gyro gain) is determined by the width of the pulse on that channel.
If your JR radio is capable of 140/140 end points then that is the total pulse width. If you have the end points at 100 its seeing less than the total available pulse width, which is why the numbers you are seeing seem strange.

OK, Aux2 on my radio is fixed at 100/100. If I were to change it to Aux3 I can swing it 140/140. I may just keep it at Aux2 mostly because Aux2 is preprogrammed for Auto Gyro Gain.
