I've got beastx on almost all my birds. And just getting into some light 3D and inverted flight.
The roll rate is slow on the "sport" setting in the advanced setting menu or whatever they called it. As compared to how fast the helis roll in my
Sim (neXt) Even on my little 380 at HHS on sport mode it rolls really slowly.
I moved it down to the next setting, "pro" I believe. And on the bench I only noticed a slight speed difference in the swash movement. moved it on down to the last setting. "Extreme". And still looks about the same on the bench.
Do you guys think this will get the roll rate moving quicker out in the field ? Maybe this is common to not see the change much on the bench ?
Thoughts ?

Thanks

Remove EXPO in radio if any and test each setting in field.

What you see on the bench does not reflect actual in-flight behavior.

Pitch, roll, and yaw rates are software-controlled gains that affect flight behavior based on control command input, motion and sensor feedback. These are dynamic behaviors that won't be seen with the heli sitting still in a static condition.

The settings are maximum rates that the gyros will allow the heli to move in each axis. Actual rate is based on the amount of stick deflection at the transmitter.

For instance, yaw rate (tail rotor) can be set such that for full rudder command, the gyro can be set to allow a maximum "spin rate"of the heli to be slow (let's say 100 degrees per second) for full rudder command, or set for something much faster (like 360 degrees per second) for the same full rudder command.

In either case, a rudder command of something less than full rudder will cause a slower "spin rate."

The rate setting that you enter is the maximum allowed rate, a "not to exceed" rate. This allows you to perform pirouettes that are agonizingly slow, or tornado fast, all based on how far from center the stick gets moved. The number you enter is the speed limit.

Thank you mr. Shema! That's exactly what I was hoping to hear. I best go back and just try one setting at a time to see where I like it

PARAMETER Letter G
Cyclics Response

Menu point ( G ) adjusts how aggressively the AR7200BX responds to cyclic commands (roll and pitch)

There is not a great deal of roll/flip rate difference between the modes, the biggest change is the expo so the Extreme setting has little if any expo whereas Sport mode has A LOT!

The way to increase the roll/flip rate is to use Transmitter mode and simply adjust your dual rates % for aileron and elevator in your TX and also add your own expo.

FWIW I use 125% dual rates (max for Spektrum) and 20-25% expo and I fly thumbs. Roll/flip rate will also increase with increased head speed or lighter blades.

Cyclic response (G) in the BeastX is only how quickly the heli accelerates upto it's full roll/flip rate.

Pot 2 (Cyclic feed forward) is for the very initial servo response to stick input, you would turn this up if you wanted to do old school crack moves!

Hope this helps.

60% of the time, it works every time!

I'm just trying to get my models to roll quicker. Like they do in the sim. They all roll slowly on the factory settings.
I have. I idea what crack moves are.
So your saying I need to put the roll rate on user defined mode ? Not extreme for this ?
And adjust in the radio ?

"Remove EXPO in radio if any and test each setting in field. "

Yes, and there's a way to get the beast "out of the FBL control loop" for bench setup...to prevent the beast FBL from "taking over"...

Had a Blade 450X with the AR7200BX...or was it the AR7000BX...I forget....used to drive me nuts when I was in FBL mode when adjusting something.

Flew a few packs yesterday. Parameter G - cyclic response did absolutely nothing.

I'll go in and set it for transmitter settings mode and try that.

CONTROL BEHAVIOR

When you were playing with this on your first post, it was implied for you to test each one which includes the last setting as well...transmitter.

Next step was to remove any expo (assuming if any) in transmitter THEN presumably unto parameter G.

Finally, IF you're a Demigod and it's still not fast enought, then reverse expo. So instead of going into positive values which adds expo (I.e. Spektrum Tx), you go negative. Opposite in Futaba.

Incidently, in what positions do you have your A,B,C pot-dials? Consider testing above quest with them set at 12 position (default)

It only takes less than a minute flight to immediately notice-feel results and since a PC is not needed, changes can be made on the spot.

Edited
Fixed Expo info as I had them reversed with that of Futaba.

Yep. Like I said, next step is to set it in transmitter. The "expert" setting didn't do anything.

I have no earthly idea what your talking about with the "A b c pot dials and position 12"
That's Greek to me.

I ran thru several packs yesterday but just decided to have some fun with it and fly instead of tinkering. Had a bunch of family around. Wanting to check it out. So I just enjoyed it the way it was for the day.

Your Beastx has three screwdriver adjustable potentiometers ("pots" on top. They are labeled "1", "2", and "3". That would be the "A", "B", and "C". 12 o'clock indicates that you adjust the screwdriver slots so they are centered in their travel range - indicated by the dot printed on top, in the "dial" that surrounds each pot.

Geek Talk...

The only 3 DIALS on top of FBL and they're labeled 1,2,3 and not A,B,C...my bad. POT is short for potentiometer. Yup.

Default is center position (also known as 12 o'clock position) and where turning clockwise goes to positive values (higher gains). You will hear references made such as "turn to 1 or 2 o'clock position" and such.

DIAL #1 is the one to experiment with. Manual has description of what each do.

Edited...
Pretty much what dkshema said while I was composing this one.

Im an idiot. I was making adjustments in parameter B. I wasn't changing anything in G. G is what I need to change

No you are correct, B is what you need to change and change it to Transmitter mode as I explained above.

G is just Cyclic Response and doesn't change the roll/flip rate, again as I explained above.

I run into a strange problem. Last summer I converted a Raptor 50 to flybarless for an older friend. We used his JR 12X, which I don't overly care for, but the Raptor flew just fine with it and would do a hovering flip just great. A couple weeks ago, he bought a new DX8G2 and wanted the heli switched to it. I set up a new model and when I tried it today, it hovered just fine, but when I did a flip in was like flipping in molasses. I've tried running up the rates and that didn't help, then I changed it to transmitter mode and 125% on high rate and still the same. All I did was change transmitters. I may have to go get his older transmitter and see how I set everything in it.

Midrich right again. Parameter G did nothing.

Ok so I've never set up flybared heli before. So I've never messed with expo or end point.

So right now there is no expro and the end points are at 100%

What exactly do I need to adjust after setting the beastx in transmitter mode ?

Or should I try the B dial on the beastx first ?
