Is it possible or has any one ever tried to run your two regular tail gyros for Yaw and Elevator into the mixer (like normal) then run a 3 axis gyro on each head with the tail feature on the 3 axis gyros disconected? Or would this not work? So basicaly the two regular gyros will be feeding the mixer info which feeds the two 3 axis gyros.
Thanks guys
Ryan

Would bot even consider trying it. First of all in regards to costs. Then I do not see the necessity. I have one 3 axis gyro in mine. And that works fine. I look at it based on the model not per rotorhead. What about the programming you need to do. 1 small mistake and disaster, if you use 1 system or in your case 2 gyro's that should cover it.

Lockwire, could you possibley post a diagram of how you incorporated a 3 axis gyro into your system? I want to do the very same thing with a TH-2 GP and DJI Naza H. [Pic snipped from RC Heli mag]

Hi

Took this one from Joel's manual. So you insert the gyro inbetween the receiver and the electronics. So the corrections of the gyro affect the same functions as you steer from your transmitter. Now I have replaced the illustrated gyros with a Gyrobot...3 axis gyro in a box still need Roll, pitch and yaw as input. so 3 inputs and 3 outputs. Hope this helps. I am using a Helitronix by the way and am not familiar with the TH/2. but to me it should work the same.

Regards

Leon

I'm not quite understanding the motivation to use separate gyros + a 3-axis gyro on the same heli. You can do it if you don't use two gyros on the same axis of control. But, since you don't need those other gyros when you have a 3-axis gyro, it's confusing me why you'd want to do that.

I DID try using a GY401 on the tail while using a DJI Wookong-H, instead of using the Wookong-H tail gyro. That worked fine, but of course, I had to bypass the tail gyro in the Wookong-H so that they would not be working alongside the GY401. Anyway, under normal circumstances, you wouldn't want to do that because it's extra hardware and expense without the benefit (at least, in general, there's no benefit from doing this).

Using one 3-axis gyro per head is not necessary. You don't want to control the heads separately, as far as the gyros are concerned. You want one gyro feeding corrections to whatever mixing unit you are using.
