Dino,

Thanks for clearing that up. I misunderstood. FWIW Despite NOT doing it as prescribed (my negligence, I just updated the firmware without realizing the new requirement, and did the DIR setup, the settings stock), the units fly normally. I will redo it the prescribed way. Thanks again.

Updated both my 550 and 450 with 2.1 All really nice apart from the piro comp which does not work very well compared to v2.0 (i thought v2.0 had good piro comp). The servo 's are the correct way around. In there something else I'm missing?

Hi guys, I managed to spend a couple of hours at the field today with my laptop trying to get V2.1 set up. First thing I have to say is coming from V1.2 the new V2.1 feels MUCH more natural - more flybar like. V1.2 had a sort of disconnected feel to me, but the new version feels so much better.

I innitially had the Simulated Flybar Parameter engaged at 30 and also Cyclic Pitch Acceleration at 30 but ended up turning off the Simulated Flybar and left Cyclic Pitch Acceleration a 0. This felt much better to me.

I also had to play with the gain dials on the unit. With both dials at 12 o'clock I had very different gain values - Aileron was 98 and Elevator was 70. I found that the Aileron gain was too high and it had issues with fast rolls and Aileron Tictocs. I ended up with Aileron at 90 and Elevator at 85. So far this seems ok.

I have set Collective Acceleration to 30 and lowered Swash Level Speed to 30. Both Aileron and Elevator Roll/Flip rates are at 60 and I set my initial pitch at 13.5 degrees.

I may still tweak things a bit but for now I feel it's working pretty well. I did some very fast forward flight - hands off - and the thing flies like it's on rails. Piros are solid and both Aileron and Elevator Tictocs are clean and controlable. Hard stops are crisp and locked in. Piro flips are better than V1.2 - smoother.
Overall very happy so far, I'm glad I made the change from V1.2

Cheers

Futaba 8FG I end up with-
AIL-36
ELE+46
Is this ok??? Because the way I read it they have to be the same!

Cheers

Some one correct me if I am wrong, but I don't think you set elevator to 8, you just copy the number from aileron over to elevator.

Looks like your swash plate is not aligned. You have different angles in a round.

I would certainly check swash is level , but looking at the video you don't set elevator to 8, you just copy over the value you have in TX in aileron into elevator.

[Dino Spadaccini]

that is correct 8* on the cyclic is the max you want to setup on the bench with both the alr and ele being the same numbers. If you need more then thats went you go into the software and turn it up

Flew it today its not bad. Just needs some getting use to. Tail is a bit fast thou. I have some videos being loaded on to youtude.

My problem has not gone away. After updating to V2.1 I had major twitching of elev, ail & rud and almost crashed me. I tried reinstalling v2.1 by reverting to 2.0 and then reinstalling 2.1 but it did nothing different. I then uninstalled 2.1 from my computer and reinstalled 2.0 software that worked perfectly before. I reverted to v1.2, power cycled the 3gx and then updated to 2.0 again. Went to fly it and the major twitches are still there. I think something in the v2.1update I originally did messed up something in my 3GX unit. Looks like I might have to replace it because now I am scared of it and don't want to destroy my heli.

[dna001]

Are you shore you don't have a lose wire, you may have dislodged a wire wile plunging in the 3GX, just a thought.

[dcanon]

Made first attempt with 250DFC today. Was totally rubbish. Completely unstable by elveator. On every movement tries to make a full flip.
I guess I can be issue with a gain of elevator but in the new software I found nothing about gain. Only monitor which does not affected by dials on front side of 3GX module...
Where is gains now?..

Just upgraded to 2.1 on my 550 v2. Super stable in the hover. Hand off hovering is no problem. It just stays put. I did not have the backwards drift with 2.0 and do not have with 2.1 either. Have to run with 75% D/R though. 100% is very twitchy. Also using 15% expo in the TX with no issues to report with 4 packs in. I had a bit of porpoising with FFF in 2.0. It has been eliminated in 2.1. A++++++++++

Are you shore you can use D/R ?

You shouldn't have to use d/r. You should be adjusting the flip/roll rates.

They work fine. Was using D/Rs on 2.0 also. I can't be bothered to take the computer out for minor tweeks or using the transmitter to adj the 3GX.

For me they work great I have no issues using them. I like to have a high and low setting and take off and land with the lower rates.

You dont use computer or transmitter to adj the 3GX. you just press the button on the 3GX and set roll flip rate on the 3GX

I have 3GX and the small compact Disc containing the V1.1 software / Firmware.This loads and runs fine on my desktop with Win 7.

When I down load any of the updates more recent than 1.1, I get an error message stating my version of Win is not compatible. How can this be if I am running V1.1 just fine.

Any ideas?

[spidermonkey]

So basically you want us to use the 3gx for all adjustments. What will happen if they/we don't want to and use the D/R or Expo like they/we are used to???

[helif]

This is what the 3GX v2.1 configuration program says:
"Helicopter's cyclic pitch exponential setting, range is 0 to 5, larger value for higher center point dampening. If exponential function of the radio is to be used, this value can be set to 0."

I take this to mean you can choose to use 3GX exponential setting or radio exponential.

[heliphlier]

Finally got around to the upgrade after a few failed attempts. It really seems as though these 3Gx units are a little particular when it come to using DX6i and separate RX. I had to re-bind, revert, and re-update firmware a couple of times as I was getting that strange servo arming where the one aileron servo when arming would go to full negative. Not to mention I for some reason could not get the dang horns to set at 90 deg.
At any rate I now have the unit set up and it is much more stable than v2.0 but the one question is can I use expo on the rudder? I reduced the epa via the transmitters travel adj. but that doesn't get rid of the direct feel around center like I need. I need to soften it up a bit I am not that good at clean collective inputs without giving a little rudder. So I was wondering about Expo on the rudder. I put it in and all seems to fly well but I don't want any issues in the future as a result.
Good job Align I think you are on track with this one I have read more positive feedback about v2.1 than I have since the release of 3Gx.
