Jack, thank you for your clarification. I cant wait to improve my model not make it easier to fly. My apologies, I thought wing rock on cross winds was the hard part. I also though stopping a roll taking into account how the model behaves was also hard. I see that is the easy stuff and the gyro is only taking the easy stuff away.

I always though the fact a jet flies like a jet is what made it harder, I now realize if I make it fly like a pattern plane it is just a simple thing, and not really making it easier to fly.

I now see the gyro is only, not sure of the word, I want to say helping but that's not allowed, its doing something, but NOT making it easier to fly.

I now understand and cant wait. I think I am going to be a pro. I feel it.

I'll run some test and report back!!! Thanks!!

I do think a good use of a gyro Is to make a scale jet look scale in the air. If you fly a light wing loading jet it will get tossed around.

I haven't flown my mig yet but I expect it to be floaty, the gyro may help.

For a guy that hates to be critizied.... You sure do a lot of it.
I still can't figure why you are all fired up.

Actually.... The JR Axis gyro has a heading lock mode at neutral. And it will hold the plane knife edge hands off. It will hold it in a hover... Mostly.

It it will force the plane to stay where you left it. So if you roll more than 90 on a knife edge pass and let go.... It will hold a crappy looking knife edge. Lol.

Im not fired up, just being a smart ass. There is a difference.

I am curious though Joe, what if occasionally you didn't have a perfect landing with a your f-86 sabre of f-16 (if you had one). How serious would you take someone who wants to give you advice who is flying a jet mach or falcon 120 and lands it perfect all the time. I've even had a guy try to show me how its done on a foam habu.

That's my only point. Its lost though.

Might want to mention you HAVE to have an S-Bus or X-Bus system to use it if I'm not mistaken.

Your point is definitly lost. You have an issue with a few fools at the club and apply that to everyone that is pro gyro on RCU.

The problem I have..even though the support for Gyros in this thread is very high...I really think very few Jet guys at Jet rally will admit to using gyro while pointing fingers at someone else landing without one.

What do U mean by Regular mode for Knife edge? I have a few students with the Apprentice S and it's a great Idea. But I don't see where the Safe Tech will help Knife edge. I say this because I can have them fly the pattern with out them having to concentrate on the plane (Just let it alone). If they don't know where U want them to fly they don't learn to fly the plane it's flying them. If they can't put it where it's supposed to be they don't solo. To many so called pilots that if they come close to the runway on landing that's good enough ...NO IT'S NOT.

By regular mode i mean the expert mode (no stabilization). THe gyro will take care of all the couplings, and you can do knife edges, inverted, point rolls... everything that a high wing trainer should not do.
You still need to do all the typical inputs of the maneuver... the gyro makes the plane "true"

But guys, no one needs to get a gyro... it is personal preference. but don't dismiss it, or assume it does things that it doesn't, without trying or experimenting first

I'll have to give it a try next time my student brings it out Thanks.

I see that is a market for Gyro's, but the price is to much for a piece of hardware with a good algorithm as software. The hardware should be cheap to produce, but the software is time consuming.

Kv. It's the integration that burns the labor in development. But that time yields the results you are seeing in today's systems. And the work for ease of integration brings it home for the regular modelers like me.

I have retrofitted cortex gyros on just about everything I fly. It makes my experience far more enjoyable and my confidence higher especially in poor weather and wind.

My my crosswind flying has become so much better. Thus I fly more which makes me better. And so on and on. it reduced a major barrier for a lot of people in heir models. That's what it does for me. My personal choice was the cortex for that purpose. I liked it so much that I promote it now. Have fun out there guys. We are all in this to have fun. Anything that adds to that experience I am for.

i put one in my big world Kadet and it made it the favorite club trainer. We play pass the buddy transmitter often with new pilots. For example. Even in windy conditions

Initially I started with the cortex in my Bobcat... now every single jet I own from a Habu 32X to Ultra Bandit has the cortex. Each flight mode has a different gain and it makes flying enjoyable. The ease of setup and reliability right out of the box has made the cortex our number one gyro at our field.

Yes you are correct. That's the beauty, for a large complex plane it is very flexible in setup. For example, I'm building a Exclusiv Modellbau 50% Challenger II, that has 8 aileron servos. No issue for the Axis setup.

I'm not a fan of having the power run through the gyro on larger complex planes.


I've heard great things about the Cortex and the Igyro.

Agreed it's a feature but its also a limitation.

Not saying anything bad about the gyro, but it will save some bashing from folks that order it without fully understanding.

I agree that it does limit to Xbus or Sbus systems. Your point is completely valid. Since this is the newest system on the market and from a long time Gyro developer, JR... here are a few points from my perspective.

There are also huge advantages to utilizing this setup for those that can, for example:

-unlimited servo setup as I described above
-can setup as many gains as i have flight modes available. So, on my XG11, i can setup 6 different gyro gains, and mix heading lock vs rate on any of the 3 axis independently.
-I can adjust all the gains independently for each axis and for each flight mode, in flight from the transmitter.


I know a ton of guys flying the Cortex and Igyro, and are happy with them. Here's another alternative for the JR and Futaba users.

Once the 28x gets here (don't flame me), i'll put the axis into my Futura... can't wait.

The AXIS is XBus or SBus input. PWM or XBus output only. As far as gains go, your are only limited by the number of Conditions or Flight Modes your Tx offers
