I am setting up the Beast on a T-Rex 470 with a Taranis radio. The output numbers on the radio go from -100-100, and not having any prior experience with any of this equipment I made a guess and set the gyro gain to 80 and -80 and with side sliders for each that would add ±10 to each, with the end result being a variable number for both HH and Norm to be in the 70-90 range. I powered up the heli and watched the output leds on the Beast as I moved through my range and they would shoot "off the end" basically light up to N, and then going blank and lighting up A. After this I decided to get the gyro channel on the radio "ranged up" such that 0 was dead center between HH and Norm and that the ±100 would just hit the ends. I ended by adjust center from 1500μs to 1520μs, and then my range down to ±80 which equates to 1111μs-1929μs.
Given these settings I now have my HH/Norm settings a 70 ±10 which puts me at the G light with a range of 2 lights on either side.

I am wondering what sort of range other people are using with their radios?

Gain values depends on tail rotor size and speed.

While hovering, adjust in HH by increasing until yout tail start to "hunt" (rapid left and right corrections) then decrease until this tail wagging stops.

Then I would use same "opposite" value in Norm mode.

Test in fast forward flight to assure that gain value is still good. Chances are you will still need to decrease some more.

Thanks for the response, but I was actually asking about transmitter values required to go one end of it's "throw" to the other? Do you know what I mean?

Understood. You want to compare actual radio numbers.

You already figured out how to set the range without over shooting pass the letter A to N. (0 to +-100)

Ouch, now my head hurts!

Sounds like you're overthinking things. Rudder travel end points should be left at default in your radio (+/-100 or whatever). You set the tail servo end points in step E, move rudder stick one way to the limit without binding and release the rudder stick and wait for the light to go solid then do the same for the other end limit.

Gain is simply adjusted by your Gear channel end points, or use the gyro function if you have assigned the gyro function to your Gear channel.

Ignore the radio numbers and lights on the BeastX for setting the gain, just adjust till the pitch slider on the tail shaft reaches either limit just as the heli reaches around 45 degrees as you rotate/pirouette the heli by hand. This is a good starting point, you can fine tune once your flying.

Oh and don't bother using rate mode unless you are only going to be flying the heli like a plane!

60% of the time, it works every time!

...I'll also add that you want around 90 degrees (No less than 90 ideally but no more than say 120) of servo movement from limit to limit so adjust your servo arm length to adjust this.

Also, don’t worry about the numbers on your transmitter,look at where the light is on your beastx when you adjust the numbers for gyro gain. For a 450 size start at letter D, fly it and go from there, if you need more tail authority, go up a few numbers and if you need more go down a few numbers. Good luck...
