Bavarian Demon Cortex in a Bandit

Goose (Dave),
I turned the HH off in the software on both Modes and verified on the ground. I'll have to go back and look, but I "think" the light is still green in one position, but it isn't "holding" the servos when I move the plane. I'll double-check next time I have it out of the trailer.

The cool part is a someone can just wire it up, learn it, and go fly.. Danny snuck one in on a friends plane and it was an amazing addition.. .. Bob B has one in his Habu32 and loves it..

Yes, you can make it attitude in either bank.. the colors orange and green simply signify which bank you are using.. the orange bank comes from the factory set as attitude.. all of it can be overridden in the software for more advanced setups.. but you need to look at the relative settings in each bank.. by default, because they are different..

Yeah, Jose does the PNP method all the time. I just wanted a little more flexibility for my set-up.
Thanks for all the info.

Hi I have one in a turbinator and it is a great adition it forks great have you ever put the gain whit the throtle so wen you have full throttle your gain is low and at low speed your gain is hi?

I recently bought one, (at Florida Jets), and it looks to be an older version since the bravarianDEMON is written in white, no "A" after it. And I can't find a serial # on the unit.
So to get this straight, I can download and install the v 1.3 firmware and operate it in a turbine powered model without the acoustic hood thingie?
I've read what has been said about orienting the device in the model, but being new to gyros, I have a question about where. Is there a preferred location relative to the model's center of gravity?

Just FYI - I fly several Cortex gyros with the older firmware (1.1 I guess) without the "acoustic hood", even on smaller turbine models with higher RPM (Kolibri micro turbine). From what I've heard and read this hood is only needed for turbine helicopters. I did not observe any kind of swinging-ups even during high speed flight.
You dont have to mount the cortex near the CG, just the correct orientation is important. Either as stated on the installation note or in the configuration software, if you want to mount it in a different direction.
I found the initial setup a bit tricky as there is very little time to go through each axis on the sticks. Very little time between each step, but after a while you get used to it.

[QUOTE=mr_matt;I have seen this gyro in action and it is very impressive, but I had not seen anyone having the adjust the gains in flight (manually I mean)
I thought this unit had some magic secret sauce and you did not have to manual change the gains while flying?
Matt
I installed this unit in a friends Electra recently with one gain setting. Model flies on rails at all speeds. He uses a dx8 and wanted it simple so I used a three position switch, determined which side of the switch was rate mode set it to 46%. I set the other side of the switch to 0% effectively turning it off. So he has two off positions and one rate model. After the first flight the gyro NEVER gets turned Off. I never used the PC to set up his gyro. When I teach the gyro in the model during programming mode ensure your control surfaces move the same amount. It really is that easy and simple to program a Cortex.

George are you still using a Futaba TX? If so you can use the gyro menu to control the Cortex gain settings. It's really slick how it works. Switch sequence is Off, rate 1, rate 2
I'm reading a lot of great ideas in this thread.
However, you set up your Cortex make sure you can switch it off.
Should the gyro ever break loose from it's mounting and you can not turn it off,
it will make for a really bad day at the flying field.

Someone asked the correct orientation..
1. with no changes via the software, put the servo slots forward
2. with software changes, you can orient it any way you want, just gotta tell it..
good stuff

Goose,
Are you able to advise me of the set by step process to set up the DS16 for use with the Cortex Gains.
I have up until now been just using the 'servo travel' to adjust the gyro gain. For example -40%. I looked at the gyro settings in the DS16, but I didn't have much time to play with it. So I took the easy option.
Cheers,
Mort

I don't have any experience with programmable gyros in aircraft but I don't think you would ever want the green light (heading hold) to be on in flight. I am surprised it is so easy to get that during programming. It sounds like green doesn't mean GO in this case... Heading hold means that the gyro will try to maintain a heading as long as the stick isn't moved. So if you yaw the model by hand, for instance, the rudder will move left or right to correct and only center when back on the original heading. This will cause very undesirable effects in "uncoordinated" flight. Anytime the ailerons or rudder are commanded at the transmitter independently the gyro will fight to maintain a compass heading with the other flight control surface. This is one of the biggest learning curves with helis. guys are forced to use the yaw and roll controls much more aggressively when heading hold is engaged. But unlike aircraft helis can fly backwards and sideways. Why is the green bank even available?

And yes, I can turn it off whenever I need to. This is a must!

Using the Futaba Gyro function the LED will only indicate either Red(OFF) or Amber(Rate 1 or 2)
George you will want to go to the GYRO Menu, select "NORMAL" instead of "AVCS" in the gyro function window. You will only use "GYRO ONE" it has three selectable positions.
Then select your switch to control the OFF/Gain settings, Next set the first switch position to 0% (OFF), Nest to XX% (Low Gain) Next to XX% (High Gain)
Verify the LED IS Red/AMBER/ AMBER by moving the switch to each position. You can even ad in a VR (varible Rate) with one of your Sliders.
As usual it is much easier to do this with the TX Handy.

Its easier to just use the servo travel initially until you find the magic numbers.. then enable the gain... when you are ready, go over into the DS16 2.4 thread.. I posted basic setup post test flights..

So I'm using 2 Futaba Sbus receivers into a Robbe Futaba PSS2018 battery backer. All Sbus servos get fed off backer serial output with backer deciding which Rx input to use dependent on signal quality. Is there a way to use a Demon Cortex to take serial data from receivers as input and output gyro modified serial data to the backer?

I am using heading hold on my F22 with a different gyro system and love it So it depends on the gyro system you use. Some are designed to fly with heading hold.

Most folks just plug the cortex inputs into the various servo ports, elevator/aileron/rudder, and use the direct outputs to drive the 5 channels..

Thanks gunradd. Off topic alert but how does that work in flight? On your "other" gyro if you try to turn using only elevator and aileron inputs will the rudder try and maintain a compass heading?
I thought maybe the Cortex is a heli gyro being used in aircraft now... I guess I am going to have to try one of these things! I like the Cortex because I am also a heli guy and I love Esprit Models and Danny is great to deal with so this would be the one for me.

Well with heading hold on the aircraft will always try and keep the heading. So you could go knife edge or inverted and all you would do is roll the plane and let the gyro work I find mine still takes a little input to hold but not much. Only time it gives me trouble is when I am on the ground pushing it backwards it goes nuts. So I turn it off on the ground but from takeoff to landing I am in heading hold mode the entire flight. It really helps when hovering with thrust vectoring also. BTW I am using a cheap eagle tree guardian and its designed to fly with heading hold so this might not work with the cortex not sure.
From what I hear the cortex is awesome and would love to have one. But for now the $55 Guardian is doing me great and I wont fly without a gyro now in my jets.

You may want to look into the Bluelight Ice Man Gyro. $80 shipped from Amazon. No I don't work for the company or sell them. You can program it to do almost anything except fly the jet.
