Actually I just read that adjusting the number 2 dial on the beastx... the direct cyclic forward. Will not effect the max roll rate. So that's not gonna help.

Parameter B
Or is perameter B. Putting it at the light blue solid what I want? That way I can change to transmitter settings ?

There is no option in perameter G for transmitter setting

I got perameter B set up for transmitter adjustment today. Had time for a short flight before dark. Set the throws or endpoints
At 150% and
The expo to negative 50% for aileron and elevator. I pretty much got the roll rate I'm looking for but WOW, it's Twitchy !!!!
Too touchy !

negative 50%
If it's not a Futaba radio then yes that will be very twitchy! The more you increase the DR's the more expo you will need so if you have maxed the DR's AND gone the wrong way on the expo by 50% im surprised it's still in one piece! See my PM.

Also forget about end points, it's Dual Rates you want to adjust, it's far easier.

Yep. The negative 50% expo was pretty scary. Rolled fast tho lol. Faster anyway.
But yah, too hard to fly.
Gonna have to play around with it some more.

Woa...negative expo? I roll pretty fast already with 100% travel and some expo. For OP, do you have enough servo throw, pitch, headspeed, direct feed, cylic/pitch throw(step L and K)? Menu J, the magic 6 degree, can also be increased a little to make it faster, but only at the very last. I have setup so many bx and never had any flip/roll rate problem. I usually do about 13 pitch and 9+ cyclic and I always start with those before adjusting the rest.

I did get it where I'd wanted it
I was making the mistake of trying get my helicopters handling just like they're set up in the neXt sim. In the sim they all roll quickly with minimal stick input. So it made all my
Real birds feel like they rolled slowly.
I was able to advance persmeter B and G ss well
As move the Travel to the full 125% on my spectrum radio from 100% (less than full)
And archived what I was looking for.

No. Read the manual again. That step is to teach the Beastx the relationship between servo movement and blade pitch to give it a baseline for the PID gains. Blue light at 6 degrees is optimal but you must ALWAYS set 6 degrees no matter what colour the light is!

Also 9 degrees cyclic isn't enough, optimal is 12 or above. This is not the amount of cyclic that is used in a roll/flip, it is excess cyclic pitch that is required for the system to control the roll/flip rate even at full cyclic stick. It's the same as the tail, you set full tail pitch which can be upto 45 degrees but only a fraction of that is used to do a controllable piroette. The rest is used IF NEEDED against wind, changes in head speed etc. to produce the same piro rate and to produce sharp positive stopping power from a fast piro.

60% of the time, it works every time!

I'm just saying some guys actually increased beyond 6 degree, not that I ever did. I always do 6. 9 or 10 is just where I like to start with the cyclic limit and increase slowly depends on how much I need. The point is to avoid binding.
