BRAIN Frequently Asked Questions

I adjust max setting on the cyclic setup before it binding but how do I adjust what pitch setting I want to fly with? same with cyclic?

[Otatiaro]

Hello,

For pitch, it depends on your flying style, type of helicopter etc ...
Personaly I set it to about 12/13° max (some people go to 16° ...).

I went through the basic, suppose to have all the setting I need but there is no point in the steps to adjust for 12 pitch, it only has the option for the max pitch. How do I adjust it for 12 pitch? I thought max pitch and max cyclic settings is to tell the system its limits?

[Otatiaro]

Hello,

Set max pitch to be about 12/13°.

Max cyclic is to tell the system the limits, max pitch is just for you and to get no binding.

The unit controls cyclic so it has to know where it should stop, but the unit just pass throught the pitch so you have control over it, so you just have to setup it the way you want it.

Okay I am using DSM2 satellites with a JR12X and I cannot get channel 8,9,10,11 or 12 to work at all. I can only use channel 7 either for AUX or Setup. I even rebinded multiple times. I dont know what to do to get the Brain to see channel 8 and above.

[Otatiaro]

Hello,

DSM2 is using 4 bits for channel number, so in theory that's 16 channels.
But I did dev with a DX8, so couldn't test channels above 8th.

Also note that at the moment only 8 channels are available with SBUS too.

Is using channels < 8 really a problem for you ?

Thomas.

[vicrc]

Thomas thanks for you help.

Well hope there will be a fix as I cannot get it to work. I decided not to use the setup and just use the Autostab feature. I wanted to test how the setup works but that is less important.Hope to test it out tomorrow.

Can you tell me when AUX min is normal flight and AUX max will be auto stab? Thanks

[Otatiaro]

Hello,

Autolevel is not enabled by AUX channel but by the Setup selection switch.
If you don't have gear or lights or something, you don't need AUX.

If you want to activate / deactivate autolevel in flight, you have to setup one setup with autostab (setup 2 for example) and one setup without (setup 1).

This is done in the flying style selection panel (last one).

Thomas.

[vicrc]

I guess I did not understand how to enable Auto Stab feature.

What I should do in setup 1 is no autostab but set autostab in setup2? so when I hit the switch to enable setup2 it will autostab the heli?

AUX is used to control other features on a scale ship maybe.

Thanks

I think it would be awesome to be able to flick one switch (eg gear/flap/gyro) to control the self level. I.e. no matter which flight mode/setup you are currently in, you always have an emergency level switch available. Kind of how throttle hold works. Is this not possible to achieve? I feel like it should be doable with a 7+ channel Tx.

In my 7HV after leveled perfectly the swash to 0° and servo arms at 90° i have this reading in collective pitch: 13.5° and cyclic pitch:12° and i have no binding at all. I set down to 12.5 the collective pitch as my liking.

But for cyclic pitch i have to try out the max without binding at the corner stick (ale-ele+pitch) or 12° is good value?

Just to understand better how Brain works.

thanks

Hello,

@CodingTom : this would require one more channel ... you already can't use governor when using a standard receiver (no sat/no sbus), that would be another feature you can't use with standard receiver, and that's not something I want.
Plus you can configure your transmitter to have the same behavior (one switch activates setup 3 with autolevel, an another one to switch between setup 1 and setup 2).

@uragano47812 : It is better to set max cyclic throw (without binding of course) and act only on gains if you need it after that. This will give the unit more options to achieve better flight caracteristics.

Thomas.

[CodingTom]

Ahh, I think I was just confusing myself on the definition of "setup", thinking it was synonymous with a particular idle-up setting. Of course idle-up (throttle/pitch curve) is independently set within the transmitter. This is what I wanted. Sorry for the confusion.

I have an 8FG tx. Is it possible that instead of having 3 switchable setup options, to only have 1 setup possible and have 1 channel control the tail gain and another channel control the cyclic gain (LD and RD knobs on the 8FG)? This makes it really easy to find the right cyclic gain without having to land and hook up the brain to the software.

It will be great if you can add some words directly on the wizard for better undestanding.

In the advance option for autostab, can someone explain what the 'Maximum Angle (degree) setting does?

Also, is it wise to set the autostab gain to max to get the heli to autostab quickly?

[vicrc]

Is there a feature with the Brain so that when I start it without a computer I can have all the servos sit in its neutral state (setting that I have set level for the swash and tail) ? Basically a check mode function without hooking up Brain via usb to PC.

I don't want to go back and hook up my computer to this thing every time my heli needs adjustment or repair. The BeastX has this feature and it helps a great deal at the field. IMHO its a pretty important feature in a FBL unit.

With autostab ''ON'' while flying around, when you move your cyclic stick the heli will tilt according to the direction you move your stick, as you release the stick the heli will ruturn itself on a level position, the angle is the amount tilt you can put the heli while you give maximum cyclic input, if the heli does not move fast enough for you in stab mode, just increase the angle, but beware to not built up too much speed because you only have that same angle to stop the heli.

The gain should be your control rate, at 100% gain it's 100% of your control rate setting in that tab, if you have slow roll rate, you will have slow bail out rate.

This is why we have 200% available gain with Skookum to avoid slow bail out.

In the GOV & STAB section of advanced setup the 'Aileron Angle For Hover' slider doesnt seem to move the ailerons very much, if not atall. (this is when Autostab box is ticked).

And yet 'Elevator Angle For Hover' works perfectly and adjusts the elevator as expected.

This has been the only problem I've had. I did a test flight today and everything seems great-APART from this AutoStab feature. The aileron always wants to tilt Left when switched in and doesn't seem to work correctly in flight-( impossible to hold a hover)

I really need some feedback on this as it is half the reason for buying this particular FBL unit.

The setup software is v1.0.002

Has anyone else had the same problem?

Feedback from MSH wecomed!!
