Heading Hold Gyros in an Airplane

As a novice, I was researching Gyros and wondering why any "gyro" would not work in any axis.

In Short;
I found that Heading Hold is actually how it acts rather than how it works.
And that most HH gyros can, in fact, be used for airplane stabilization.

After searching I finally found some links that had the info I was looking for, and at a level I could grasp.

To Start Go Here;
http://www.mycoolrc.com/gyro/index.html
http://www.mycoolrc.com/gyro/indexnew.html

I found a lot of usefull info there, and in simple terms.
Follow the links and you will find info on a lot of different gyros.
What, Why, and How to use.


Ebay is flooded with cheap Esky EK2-704B HH Gyros @ $15.55 delivered US.
Or the Detrum GY48V for in the $18 to $20 delivered US.


Thanks

It's just the difference between heading hold and rate hold I think that is the distinction. Some (or most) can do both, depending on the sensitivity settings. At least the one on my heli can do both.

Yeah, they describe it as a headlock gyro, but its both, headlock & rate mode.

The Esky 704b looks to be both as well, and is one of the main 3 that gets discussed in the thread. I plugged my GV48v into the gear channel, then set the gear options to 0/-30 on my TX (negative = rate mode%, positive = headlock%). You can probably do the same with the Esky.

If you have a knob on your TX, you could probably dial up and down the sensitivity and mode in real time.

I noticed this myself today, flew my P-51 with a 10x8, and I could feel the extra speed over my previous 10x7, and slightly shorter battery life.

Now you drive safely you hear.
Thanks but me and the wife flew. The brother inlaw and my son drove the truck and just got here. Floating in the pool with a few beverages then snoozing. Unload the truck in the am then go gator hunting in the back yard. Saw a snake the size of a boat oar I need to kill. . It's 1am and there are stores open 24hrs a day who sell beer.
Like the ball player said to Kevin Kostner in Field of Dreams....."is this heaven?"

Here is a 3 minute video of the Microdan Skysurfer with two rate gyros installed (Esky EK2 0704) on the ailerons and elevator. This is the second flight after my first which had the gyros reversed. What a handful that was with the gyros fighting the flying of the plane. After landing and switching the gyros to operate correctly you can see it really handles the wind well. Amazing. Wind was 15 mph and the Skysurfer was extremely tolerant of the wind. The Skysurfer is a good flyer in the wind without gyros but easier to fly with them.

Note that at about 45 seconds I video another glider and you can see the wings rocking in comparison to the gyro equipped Skysurfer.

I found this video today, it's of a guy flying a sky surfer beautifully in what he claims to be 15 mph winds.

I think i seen someone take it out and do some trimming of the mount and bolt it on form the back, im guessing the X mount well not fit?

Hi again

Today I flew my heavy FPV Bixler "LOS" with a CG 7.2 cm from LE... and for the 1st time I could really have a better feel of the plane ...

1-It glides hands free.. no diving this time
2- control is greatly enhanced

So I'll try 7.4 cm CG next time .. finally I'm getting there ...

Thanks a lot to all of you guys for the help you've provided

Here are some photos of my ugly fat FPV Bixler

Hey guys, I have the stock motor with a 2200mah lipo and my AUW is 38.5 oz. I do have a 6X4E prop. Do you guys think I'll be able to get her in to the sky?


I played with laying 3-4 layers of carbonfiber in the fuse and put a kevlar/carbon fiber nose on the plane and did the normal mods like putting CF in to the rear stabilizer and rudder and on all the control surfaces, solid Carbonfiber spar, made new control horns as the old ones snapped on me and taped up the wings with extreme tape. The plane is pretty much crashproof but IDK if I'll beable to actually get her in to the air. I have a spare 2600kv motor and wanted to hold off on putting that one in this plane just to see if the stock motor could work. What do you guys think?
