Hi OlliW,

Please tell me how can I login to your site to get this firmware. I've registered and got email with password in return, but unfortunately I'm getting following error:
"Du hast nicht die erforderlichen Rechte, um auf diese Seite zuzugreifen." My knowledge of German is "nicht zu gut" but in my understanding it means "You don't have required privileges for login to this site". What am I doing wrong?

OK
Helicopter took off successfully with tail perfectly stabilized.
Yes, add me to your web page.

Cheers

hey Dazur,

ha, you have not done anything wrong... you just need to give me the chance and time to approve your registration request...
Should work now. So, welcome to the club.

hey Cosimo,

fantastic. Thx for reporting back. I've added you. Maybe you could consider posting your setup and parameters (heli type, transmitter/reciever, head speed, tail servo, Rate Gain, PID Gain, PID I, frame length, debounce, etc. pp.). There are still too few of these reports to see trends for useful parameters...

heli:
Tx: turnigy 9x reflashed with er9x firmware
Rx: turnigy 8 channels 2.4Ghz
head speed:
tail servo: MKS480
GA250 parameters:

Thanks OlliW. I just flashed it and it looks like everything is working perfectly. I plan to use it in a fixed wing so have to become familiar with all those options, but it'll be a joy I'm sure. If those two I own meet my expectations I'll buy a next batch for future use. THANK YOU VERY MUCH FOR YOUR EFFORT FOR THE COMMUNITY.

Hi ablack,

For testing purposes I will put two of them to my small EPP flying wing. If they pass this test then will be used in 1.8m nitro Decathlon on tail and ailerons. Can you share your fixed wing settings?

P.S. I noticed on the bench that with this gyro is not possible to use trims. After every gyro reboot it centers the servo no matter how much trim I apply even in rate mode. Is it normal? I have two other piezo gyros (E-Sky EK2-704B) and they allows me to use my trims.

Just subscribed to this thread ...

Interesting to see a guy from olomouc, a city that I did cross my car countless time, and the first polish guy not far from my polish place 'wroclaw'

Still studying the work of OlliW ... thinking if I will ever hack my ga250

Tchuss

E_lm_70

Ps: in the other world I read exactly what did puzzle me ... this gyro has 3 free pin, 2 in, 1 out ... perfect for map a normal usart ... instead of hacking with diode and use 1 line only ... if just firmware would be open ... it will be nice to play with it

I'm a newb. Just putting it out there.

I got my parts in from HobbyKing. Once all the soldering was completed everything else was straight forward.

I did have to burn the bootloader twice before I could flash the firmware using the avrloader.

I uploaded the firmware and left all settings at default for the time being. Flew for about 3 lipos. Tail was holding excellently. Unfortunately I am still learning how to fly a little better.

Hi,
yes you have to trim all mechanically and not by trims in TX. I did it on the ground so all is in one line when still and 0 trims.
Then fly with gyro OFF to check, make slight changes and then in most cases its OK after one or two flights.
Or you can trim in flight in RATE mode, on the ground note posittion of trims or mechanical position and then program trim in gyro (or make mechanical adjustments).
But, when you use gyros on fixed wing all the time you dont need to make precise mechanical adjustment, gyro makes the plane stable, so no diving or rolling occurs even the plane is untrimmed.

Hi Olli,

Great work you have done here! I'm really impressed, and I would love to try your FW on my GA-250. I tried to register on your site yesterday, but I haven't received any emails yet?

My GA-250 (with the original FW) doesn't seem to work very good in my HK-250GT.
It would be nice to try your FW on it, instead of just buying a new (and more expensive) gyro.

Thanks.

@dazur:
a trimming via TX shouldn't work for a gyro in hh mode, also not for the commercials ones (and for all gyros I know, and all gyros I read about, this is indeed not possible).

if you don't like the auto-center feature at start-up, you can switch it off by setting the parameter Rudd Mid Mode to fixed (go to the Advanced tab in AvrConfig). You can the select the mid value which should be used by the gyro with the parameter Rudd Mid, a value of 0 us means a rudder signal of 1520 us, a value of 10 us means 1530 us, and so on.

@dazur, ablack:
doing the trimming mechanically is the best, but to a significant extend you can achieve the same with the Servo Mid parameter! that's why it is where, you may wish to try it.

@netmav:
patience, my friends... I am not always focused to 100% of my time on this project, you know, family, work, other projects, etc. pp
should work now though

Hi Olli,

I understand completely.
I still haven't received any emails, though? And if I try to register again, I get a message saying that the username and email address is allready registered?
But I don't have a password, and if I click on "Forgot password", both my username and email address is not recognized?
I'm sorry for all the trouble..

Now to something completely different: While I'm waiting for the FTDI adaptor to arrive, I was thinking about building the DIY adapter. But I don't have any Shottky diodes, so I was wondering if anybody know if it will work with "standard" 1N4148 diodes instead?

Thanks.

hey Martin

you've got a PM

just try the 1N4148... you can't damage anything... no idea if its will work or not (and the DIY adapter reportedly worked very dependent on the particular computer, so its hard to make any predictions anyhow)
