Default When I lower my gyro gain it affects my servo travel????

Ok,

This is a brand new build. I'm running a Ino-Lab d261-HB for the tail. This servo was working fine on my 450. The spartan (black) is from my 6HV, working fine as well. I partd out my 450 and went flybarless on my 6HV.

I went through the hole setup process on the new setup. I've built a HDX HC500, this is the smoothess tail setup I have ever come across, no binding what so ever.

What it does:

When gain is changed it acutally changes my servo travel???

In HH mode it drifts and wags.

In rate mode is wags, like bad

My receiver is an AR6100e and I have checked connections and all is right. I have my gyro gain on the gear channel and it is set properly on my DX7.


I reduced my BEC voltage bak to 5.1v. I read where some servos just don't like 6v. But that didn't help any.

I'm stumped fellas.

I am not sure if you are saying the gain actually is affecting the servo travel, or are you asking if it does?

Normally the answer is just no. the overall servo travel is independent of gain.

But what gain does is to multiply the heading error that the gyro is sensing by a large number, and then feed that to the servo. So a high gain setup would make a bigger correction than a low gain--the servo would move more for the high gain in this example.

However if the heading error is a big one, the low gain servo will make a big move, but not as much as one with a large gain.

So I guess you might interpret the servo travel as being smaller, but I suppose the correct answer is that a lower gain doesn't "limit" the servo travel. It can still move the servo the full range that you have input in the gyro setup.

I hope that made some sense!
