JR 7703D gyro and align 600n
I'm using a dx-7. Everything in normal mode is working fine. But when I switch to idle up mode 1 which is set %80 throttle it has abrupt vibrations(tail wag back and forth). My normal gain is set to %61 and I have tried from %40 to %60 gain in idle up mode and still have vibrations . Any suggestions on what to do? First time setting up JR770 3D gyro.
Thanks in Advance

The best way to setup this tail is to adjust the dial on the gyro itself for max travel. Then move the ball on the servo arm closer and closer to the output shaft until you don't have binding in either direction. That was the step that really helped my 7703D setup. I have no experience with the DX7, but the gain in my T7c is set to an almost identical number. The 770 just doesn't like having a whole lot of gain, but it still does its job quite well.

I haven't touched any settings on the gyro itself. I lowered my travel on the radio to %75 because tail was way too fast.

Yeah, with full travel it can do that. I use the Dual Rates to adjust how fast the tail spins. My normal setting is %75, but once I throw the switch it's %140 (just for giggles and wow factor).

To elaborate on what I previously said, take your adjustment tool and turn the travel dial on the top of the gyro up as far as it will go. Then find the right servo wheel/arm that will allow you to get the maximum throw without binding. This allows the gyro to utilize its maximum resolution, and you can even take the ball farther in if you don't get the results you're looking for.
