The gain adjustment on RD6000 is from -150% to +150%. That mean 0 to +150% is HH and 0 to -150% is normal.

Form example if I want to set 50% HH, the formula is 100/150 * 50 = 75%.

Does it make sense ? I'm confused now

hi there

i always thought that it was the other way round

a negative number is heading hold

but the principal is the same

How it works

For a servo 100% to 100% either way would be the 60 degrees servo movement.

So this is taken into consideration. Read the gyro setup, it should indicate for rudder servos the max ATV suggested.

I would regard more than 100% an over drive for gyro sensitivity.

I suggest (like I did on an RD6000) Start at 80% gyro.

Hover and see the behaviour. If the tail wonders increase it. If not decrease it until the heli wonders. Then increase again until it stops.

Repeat for both HH and Rate

good luck

I currently have an RD 6000 Super and 401/9253 combo. I have the gain set at 60% (maybe 65% ) and in the directions it says anything below 50% goes into normal rate mode and above 50 is HH. I started at 80% and worked it back down. As for the differences between the gain at -150% and +150% I am not an expert on...Anyone??

This is my calculation, I could be wrong.

If I want to set 60% gyro gain on 401, my formula will be :

60 / (100/150) = 90%, so I have to set the value 90% on my RD6000 setting to get 60% gain. Is that correct ?

Ok this is as close as I can get. At 50% on the TX the gyro enters AVCS or Heading hold mode. At 50% the gyro has 0% sensitivity in HH mode and 1% increase in sensitivity from there up to %150. Below 50% the gyro is in normal rate mode and has 0% sensitivity at 50% and an increase of 1% all the way to -150%. The 401 instructions show the relationship between Tx and Gyro sensitivity/ gain. The way it describes it is 0% at 50 in HH and 100% sensitivity at 100%, then 100% sensitivity in Rate mode at 0%. This is for an T8UHPS radio that I believe goes from 0% to 100%, not -150% to 150% like the RD 6000. Hope this helps.
