He most likely means -50/+50, if your radio doesn't go to a negative value try going 25/75.

dunno if this is feasible as all gains are independent abs you would need three knobs on your tx to do that. I don't know of one tx that has that many knobs.

Nope. I mean 50% switch on and 50% switch off on a Futaba T10CAP Endpoint setting screen. The radio does not do negative endpoints on the screen for any endpoint settings. But the 'throws are of course a + and - value in the flesh so to speak.
See pic below.
Chan 7 (AUX 1) set to 50/50 works fine.
Chan 8 (AUX2) set to 25/75 and the servos jitter.

No knobs needed, you simply adjust via atv (end points) on the particular channel you're using to control gain. For example, aux1/aux2/aux3 correspond to gain on ail/ele/rud. Then you'd do to aux1 channel on your radio and adjust the end points to achieve a given gain, do the same for other channels.

I haven't used a futaba radio, but if you'd program those values into a spektrum radio it would simply do nothing (both values are 50). On a spektrum radio you would need to set it to -50 and +50. Once I get my ORX v2 I will test this myself and give definite feedback.
 Dec 16, 2012, 03:24 PM Registered User Canada, BC, Coquitlam Joined Dec 2009 442 Posts The issue with ailL and ailR being reversed can easily be fixed with the use of a programmable servo as someone else on here mentioned. I'm using Hyperion servos which have the ability to be reversed. It's a shame there is no ailL and ailR input, then you could reverse in the radio whichever way you want.

Yup. On Spekky and JR you are correct. I have both Futaba and JR systems, but have not tried on the JR system as I do not use it, but will do in a few mins to try it out.

Its not unusual on Futaba

 Dec 16, 2012, 05:19 PM Registered User Canada, BC, Coquitlam Joined Dec 2009 442 Posts Also on radios like the new DX18 which I'm using there is already 2 gyro menus, if there's enough demand I can see spectrum adding a 3rd gyro menu. If the orx doesn't percorm that well I'm going to play with individual gyros (like the hk 401b), granted its a little more money (3X 11.99) but your have a lot of programming abilities.
 Dec 16, 2012, 05:40 PM chicken nuggets Joined Aug 2011 198 Posts Well, I just had a go with a JR system (X-378 7 channel) and what a mess. Jittering all over the place. I can use Aux to turn the gyro on and off, but cannot damp out the jittering no matter what percentages are set in the TX. The jittering is worse when in the 'Off' mode. It lessens markedly when the gyro is in the 'On' mode. The worst of it is when inputting left aileron with the gyro in the 'off' state - man the servo jumps around like a jack hammer! Also tried it in a Turnigy 9X upgraded with Sky9X mainboard running FrSky DJT and a D8R-XP RX - jittering just the same. Then tried it in an old 35meg Futaba T6EX - working fine with no jittering at all. Tried all three gyros I have and all the same. Will look at it all again tomorrow.

Extremely over sensative to say the least! Even with all the 'fixes' of hot glue etc. they are a nightmare! Only glad I bought two dozen 18 months ago with the MA948 can, and still have some left for my own stash!

Recommend an alternative? I have 3 401b's quacking around.

Mine was doing the same thing with an Aurora A-9. I replaced the Y connector to the ailerons from a heavy duty Hitec to a cheap HK one and it solved the jittering. I was stumped too and changed the Y connector by pure luck as I noticed that when I unplugged the ailerons it stopped.
