Rate gyros may not be enough to maintain a plane's roll orientation during a hover or vertical take-off. In those cases, head hold may help maintain roll orientation without needing large manual interventions on the aileron stick.

Yes, I understand that for 'special' flight maneuvers. But the vast majority of fliers don't do that stuff and HH only gets them in trouble.

You listed CH2 twice, is one of these supposed to be CH3?

I hope this is not a 3 axis gyro for a CCPM CP heli. Those gyros tend to have servo outputs that mix aileron, elevator and collective pitch (an addition to, but somewhat similar to throttle) inputs (this is the CCPM mixing) that will probably be a large mess to untangle for an airplane (unless they have a special setting for airplanes).
The first 3 axis gyro units that I heard about were for CCPM CP heli's.

Just mentioning that because in the confined spaces that I fly, I normally will be doing "special" flight maneuvers.

Russ, to help you out, I'm going to be blunt. Your using too many words to describe your problem without giving anyone here enough actionable information.
There are LOTS of airplane as well as quad and helicopter multi axis gyros out there. Giving a text description like you have is not going to give us what we need to help.

1) What Gyro did you get (post a link to it)

2) What Tx and Rx are you using?

3) Do you have 1 or 2 Aileron servos?

Lets start with those 3 questions above, then we can help you.

thx

BTW, if anyone is looking to buy a gyro and they are not sure about it, go ahead and post a link here and maybe someone knows of a specific thread on it

DJ,

Heading hold is a hoot to fly with in a plane. Don't knock it until you try it. The Guardian has a nice range of adjustments for heading hold in both 2D mode and 3D. The downside is the pilot workload drops tremendously and when you return to regular plane you can forget.

Bill

Bill just be aware that the Guardian is a rather special case as it does fairly sophisticated "heading hold" because it contains accelerometers as well as gyros. Agree it is fun to play with.

Simple heading hold gyros on the other hand can result in some very odd effects.

Bill I think I hear what your saying.

But the point I'm speaking too is doesn't an average flyer want or need HH. But what I'm hearing from you and others seems to be a defense of having HH for an average flier.

Bill I'm not being contentious but that doesn't answer the question. Your telling me "don't knock it until you try it" I damn near can't fly the plane now and we got wind. I thought the gyro helps that and I know it does from experience.

Someone needs to clear up who needs HH and who doesn't.

John,

Agreed. I have tried both and the Guardian is well designed and provides a superb heading hold feature.

Hmmmm ... Ok. Sorry for the messy input.

1. The gyro is a Helicox TG-1

2. TX/RX are Futaba 6J6

3. I have 2 aileron servos.

Here is the link to the Helicox site.

I have my guardian set up in 2D for centre stick wing leveling only and small "box" size, which still lets me do reasonable aerobatic manoevres but returns to straight and level when I centre the sticks. I tried the heading hold mode in 3D, but have changed to 3D rate mode only as it feels more natural to me. I suppose the heading hold feature is just one I have to play with a bit more!

ok, never seen that one. I'll look at it some more. I see the manual download so I can help you out.

The Pitch on a helicopter is an AUX or ch6, i expect you won't connect it for anything (but we'll consult the manual).

I'll get a reply on this during my day (Eastern USA time)

I use a single axis gyro on rudder on all of my tail draggers. I use the HH mode for take off then turn off (switch to rate mode with three percent gain) the gyro as soon as the plane leaves the ground. Doing it this way the take off of the tail dragger becomes a non event (unless you forget to turn off the gyro). When in the air the gyro is always "off".

Bruce

landeck
do you fly off of pavement or grass?
Tail dragger or nose wheel?

Everyone can do what they want, but I'm not much of a fan of hands off the rudder on take off. It seems like it keeps you from learning the rudder in my opinion.
In Rate mode, you still have to touch the rudder and stear it, expecially at the beginning.

Melnic, our field has both pavement and grass runways and I fly tail draggers off both. Just about 100% of the time we have crosswinds. I have been flying RC for 40 years, the first 38 without help of a gyro. Many times on short coupled tail draggers I would have to take off cross runway into the wind. With the help of a gyro I no longer need to do that. I know you do not like to use HH hold on take off but I find it works very well for me making the whole flight much more enjoyable.
