I'm trying to simplify and seperate the help pages and videos.
Here is a new format I'm working on:

I watched the aileron one - made things perfectly clear - fantastic job.

Been toying with the idea of putting in the Apprentice to help.

Need to see if you have one for the 704A now....

Thanks

thx,
Yes, some pics or a short vid talking about what I call "label sideways" gyros like the 704A, telebee, eflite and GY192 and how they are different.

I updated the list of Gyros that have been tried on airplanes that I know about and updated the comments. I also put pictures and more links to them.
http://www.mycoolrc.com/gyro/gyroLINKS.html

There is a link now to the gain switch videos on the new page:
http://www.mycoolrc.com/gyro/indexnew.html

helicow, note the new comment on the 704A and how the travel is affected by an off (low rate gain) condition.
I tested the GY400, 704A, 704B, GY401, Gy48V, HK401B and GY192 on my test board this morning before making those updates.

I need to add some information on how changing gain and turning the gyro off affects roll rates for use in ailerons. The reason is that if you simply turn the gyro off using a low rate gain, the aileron difflection amount is affected. This makes the servos reach full movement at only 2/3 stick movement. The result is the airplane seems MORE sensitive around stick center. There is a way around it but it kind of makes turning the gyro off an "ISSUE". For ailerons and Elevator where you want that sensitivety. Less of an issue with Rudder which many people don't even touch in flight.

BTW, I flew my Profile foamy with 3 axis rate mode gyros in 15-20mph winds this morning. I landed several times moving backwards at 1-2mph. .
I tried a couple Heading hold Rudder take offs in a cross wind. It was not really possible because the cross wind would just flop the plane over on me cause it's so light. I normally hand launch this plane almost straight up anyway.

Checking them out now, but your 704 video worked perfectly for me with the Apprentice. Waiting for a calm day to actually fly it.

FYI - Seems to be an issue with the link on that page (gain link).

Melnic, if I was going to purchase one higher price (above the 704 I've played with on my Corsair), what would you personally recommend for the Carbon Z Yak? I could read and try to figure it out, but I'd rather you give me a recommendation so I can then just do the research on the the best fit for me. I'm a rookie pilot and mostly just flying sport/aerobatic with the Yak now, but trying to learn harriers and other 3d stuff as well. One problem I have is I'm scared of flipping the high rate switch...lol.

Thx! And great job with the new page, layout, and vids.

Another question for you. A 3 axis gyro would presumably control aileron, rudder, and elevator. What happens if you hit a down draft while in knife edge? Would it compensate with rudder, or would it think it still needed elevator?

I have a GY48V in a new Hawk Sky (aka the Speed Hawk) that I built.

I am using the FlySky 6ch TX and with a T6Config mix on one dial and one switch can have it on Rate, HH or Off at my choosing.

If a tutorial for THAT hasn't been posted yet, I will make one (if there is interest).

Picked up a gy401 for my CZ Yak...Now I just need to figure out how to set it up...Watched your vids for the gy48 and after watching those it may take me a month to figure out how to set this thing up...lol. Not nearly as simple as the 704's; but much more capability! Hope y'all will help make sure I get this right.

Me too And the guys I fly with have a four pack coming. They are great simple gyros. And those ship from the Scotsdale, not across a giant drink.

Do you know why he is selling one heading hold and one just rate in the same lot?? 2 different types of gyro.

San, pretty sure those are both rate only gyros. The picture shows the silver body with blue label and those are the 704 (not a or b) which should only be rate. One benefit of these gyros is you set the gain on the gyro so there is no gain wire and no need to have an open channel on the RX.

Where did you see one was a head lock?
