Use or do not use dual rate on fbl?
Hey guys

I fly only scale. I use ikon fbl unity. I do use lower dual rates and expo.

My doubt is: should i change agility on the fbl software and leave dual rates at 100 or can I also set lower rates together with the agility on fbl (that's how I am flying now)

Thanks in advance

Its really up to your specific setup and you but...without getting too far into the weeds...most newer FBL controllers have you set your dual rates through the controller's interface.

In many cases just setting your rates in the tx does nothing if the fbl controller isnt programmed to accept the input and know what to do with it.

I am not trying to be condecending however, your best bet is to look into your manual. I am sure it tells you exactly what you need to do in a few simple steps. Good luck!

fbl uses agility for rates

increased agility + rates might be to fast

I wouldn't !, this is so I would always have full control of the head, what I would use is Expo on one rate and then no Expo (or a lower setting) on the second 2 rates, so one rate is for just zipping around and hovering and the other 2 rates are for acrobaticsJim

Option #1 YES, but...

Option #2 NO, you shouldn't be doing this.
can I also set lower rates together with the agility on fbl (that's how I am flying now)
Option #3 YES, what you are really after.
Set agility to ZERO and do whatever on radio.

Hi Cali,

I fly almost exclusively scale too and use Brain/Ikon on all my models, so here goes:

Start with the default values for your size of model and number of blades.

Select "beginner" - don't feel this will be too soft - my Trex 600 will loop and roll in this default. Don't ask me about "3D".

Leave the agility at the 30 value - "Agility" has a unique meaning in MS Brain language and 0 will be horribly robotic making it hard to fly smoothly. Higher does not increase agility, think of it more as "flybar simulation" whatever that means

To make the model softer (more scale-like), go to the advanced menu/set up/cyclic and lower rotational speed - I fly at 100 degrees/sec on cyclic (and 200 on tail) on my scale models but leave it at the default of 160 for the Trex. This is effectively lowering the "rate switch" without sacrificing control resolution.

Try this and see. From here you can experiment. I find the -20 expo in the Brain is fine for most models - some I up to -30 to soften the response around center.

I have played with Agility. Going low makes the model very robotic - going high can make it feel "loose" and will require you to hold in some cyclic to fly fast.

Example of this set up is here:

Good Luck

I used dual rates only briefly when I first started flying.

To me properly set up exponential just made it unnecessary.

Dual rates seems like it was probably more applicable on older systems with more analog equipment, where it was a way to get finesse and speed out of one model.

Modern fbl is just another digital "governor" that gets us finesse and speed in the same package.

Oh yeah and correct me if I'm wrong but it's important to note that in my spektrum tx positive expo is what softens the center and in my ikon fbl negative softens the center.Goblin! where have you been all my life?
