DX8 gyro setting for 300x

[sjonak]

Been flying my 300X with a DX6i and it has always been rock solid. Got a new DX8, put in all the setting as per the 300X manual and now my tail is "twichy". I understand that there may be some better gyro settings. The manual settings are:
Norm: 54
Stunt1:54
Stunt2: 54
Hold: 54

Any suggestions?

Should be as simple as lowering the transmitter gain.

Sorry, I should probably know this but I've never had to deal with it...how do I lower the gain on my my DX8. Do I lower the setting I listed or something else?

Yes, you simply try another gain setting like 52, 50 etc. If you have the gyro switch activated you can have 3 different gains preset and switch between position 0, 1 or 2
Pos 0 = 54 pos 2 = 52 pos 3 = 50 for example this way you get to try 3 different settings with just a flick of the switch to see what range works best.

What you should also consider is the fact that the Gyro-Gain min/max values differ between DX6 and DX8.
I had the exact same issue with my 300X when I changed from DX6 do DX8 the other week.

In the DX6, the gyro gain goes from 0 to 100. At 50% the Gyro is off - anything below 50 is rate hold mode and anything above 50 is heading hold mode.

Now for the DX8 that's differnt. The min/max values are -100% and +100%. So at 0% the Gyro is off - anything below 0% is rate hold and anything above 0% is heading hold.

Therefore the Gyro gain suggested by HH of 54% for the DX8 equals 77% Gyro gain on the DX6. (54 divided by 2 plus 50%).

at 77% on the DX6 or at 54% on the DX8 my 300X would also have a very bad tail wag.
I therefore engaged Gyro-Gain values between 62 and 68% on my DX6 which translate into 24% to 36% on the DX8. With that my 300X flies stable.

Thanks guys! I'll give it a try.

After I changed my tail servo to a very high speed servo I dropped my gain to 45 to get rid of severe high speed tall wag.

+1. I had terrible wag at 54% on my DX8. Dropped down to 36% and its solid. Great suggestion.

Hi all, I fly a lot of planes but am fairly new to heli's, and have just ordered a Blade 300x as a second heli (upgrading from a mCPx BL), so i was wondering about the DX8 gyro settings (54) stated earlier in this post ... Does that mean that the 300x gyro will always be in Heading Hold mode?

Is there any benefit or necessity to setting the gyro to Rate mode for the 300x ? How would that effect the heli if used?

Also, does the gyro alter in any way as you switch between Normal, FMode1 and FMode2 on the DX8?

The mCPx BL never really had any gyro settings, and as this 300x will be my first 'real' pitch tail heli, I am just trying to learn about these gyro's as I wait for the 300x to be delivered.

Another thing, the bladehelis DX8 setup file turns off the gyro switch, do you leave it that way? or do you use the gyro switch for some purpose with the 300x?

Thanks for any clarification as I learn this new arena of RC.

Cheers

Had the same thing on mine after going to Edge blades and higher head speed. Lowering the gyro setting on the transmitter took care of it.
