just curious...i guess i am a hold out because i am still using 3g - three of them: in a 700, 550, and 500. all fly fine, although I certainly concede that there are better systems. But who else is flying 3g?

Please spare me the anti align rhetoric or how crappy the 3g system is.

I just sold my 3g and im very glad i did. I got the 3gx and was very scared of it being another 3g(bad tail) but i was very very suprised. Its rock steady from the first take off. Theres nothing wrong with the 3g i just couldnt get the tail locked. It blows out on hurricanes and tic tocs sucked.

I had to fine tune it.

The "out of the box" settings were no good.

It had a tail wag due to the rudder control lock gain being to high and the overall gain being to low. It took me awhile to figure out. But when I did, it was locked in.

They have made some significant improvements in the firm ware. The system seems to work best when it is hard mounted and strapped down.

To summarize:

It is all in the setup.

I am still flying it and looking at getting a 3GX.

I'm still trying to fine tune my 3G on my 500, tail wag issues! I have 2 more sitting there waiting to get mounted to my other birds

Any help to assist me to fine tune it is greatly appreciated!

I love this hobby!

MicroVan,
are you on v3.0?
That will solve pretty much all of the tail issues

Try bringing the rudder lock gain down to 45 and adjust down if needed, and turn the rudder overall gain up to 70 and adjust up as needed.

I am on V3... Even made an aluminum plate to mount the sensor with aligns PU tape and strapped down. Prior to that I have tried everything else.

I think it maybe my settings!

I have a JR 9303, what throttle curve is best to use with the 3G? I currently have it 0,0,75%,80%,80%,85%,90%. this is the only way i found to minumize the wagging.

What qould be the best curves to use in Normal and idle up. Also the pitch curve. D/R and Expo?

Agree.
Drop lock gain, and crank up your TX gain some.

Hey.

Try a single Align foam pad and not locking the sensor down hard, a normal tail gyro is mounted softly to avoid introducing vibrations into it and the 3G is no different.
In theory on an electric machine there is minimal to no vibrations, but there still will be some that can cause you problems.

Also try moving your sensor, I did try the 3G located in the same position on my 550E and it didn't like it. I think you you have any tail drive issues, an out of round tube drive or slapping belt then vibration gets transfered into the boom block.

Another thing is how far out is your tail servo ball on your servo arm? I found you're much better off running a shorter arm and then being able to turn the gyro gain up as a result.

I have swapped out 3G's for 3GX's on my 450 PRO and 550E, but my 700E is running so well on the 3G I am not going to change it just yet. If I do swap it out this will be the machine which warrents trying something different to feel what the differences are between an Align FBL unit and another make.

It looks like you are using zeal tape.

Zeal tape gave me some bobbles and wobbles. I have mine strapped down with double sided 3M tape, not cushion.

For me the sensor, seemed to work best when it was hard mounted.

I used the align pu tape. A piece of 3M on the boom box and an aluminum plate then the align pu tape.

I've tried just the single 3M tape, then tried the 3M with foam tape and all was worst then my current setup

It has to be my settings! Cause at certain head speed the wagging would stop :/

Hey.

Did you see an improvement with a lower or higher head speed?
Perhaps you have a vibration issue which is worse at a certain rpm range?

Sensor location makes a difference to gyro performance as well as mounting style. On my 700E the soft pad~metal plate~thin pad works well. On my 450 and 550 a single align pad worked well, but I never strap my sensor down hard. Did try it but had to lower gains so much there was no benefit to doing so, I think the cyclics might benefit from a hard mounting but the tail suffers.

I see little to no wag at a higher Head speed.
