I'm trying to setup my BW gyro and running into some problems that hopefully you guys can help with. Background Info: Radio DX6i reset to new model, zeroed all trims, and selected single servo 90 deg. AR6200 receiver with sat. I have all the wiring as per the instructions Cyclic servos Hitec HS-5245MG I have the Robird software running. When I hook up to the BW it connects. I select Setup Guide and on the first screen I selected DSM2 for the receiver type. Next tab and go to the 1 servo setup. (here I'm not sure what settings I should use for the 5245 swash servos, doesn't seem to matter.) I can adjust the neutral boxes for the servo arms at 90 deg at this point and the servos respond to the Robird software. When I go to the next screen, 2 ServoDir tab to check servo direction, I don't have any control of the servos from the transmitter. The servo arms go to a low position and don't move from that position. It's like the transmitter isn't controlling the system. I'm puzzled and would appreciate any suggestions. I have watched the setup Youtube video and can't figure out what is going on. Thanks, Curt

have you upgraded to the latest firmware?

Yep update firmware before you do anything. Is this the part where you check the pitch? I can't remember I'm not at home now to check. It ma be the part where you disconnect the wire from the gyro and check it then plug it back into the PC.

Thanks for the help guys! Still having confusion. Talked to Marvin (gerv1) on the phone last night and it helped but still not there yet.
Yep, upgraded the firmware to the latest version before starting. Marvin clarified step 2 (tab 2), I was looking for the transmitter to move the servos in the up direction. The software is just looking for the program to move the servos. Just had to reverse some of the servos to get them deflected correctly. That bit of confusion cleared up.
Tab 3 Swash Type set up as I expected.
Tab 4 is where I'm hung up now CollPit. When I move the pitch on the transmitter I don't get any change in the servos. Are you supposed to have the usb hooked to the BW when you are checking for the 12 deg of pitch? Either hooked to usb or unplugged, the transmitter pitch stick doesn't move the servos.
I'm going to watch the YouTube video again to maybe help clarify things but, any ideas you guys have would be appreciated.
Quick question: no matter what transmitter receiver you are using you should use the 1 servo 90 deg selection on the transmitter for the swash?
Thanks again guys, Curt

OK, another piece of the puzzle unraveled. I had originally selected DSM2 for my transmitter type. I just tried PWM for transmitter type and now my swash is responding to transmitter stick inputs.
Not sure why DSM2 didn't want to work for my DX6i but PWM seems to be the right setting for transmitter.
On to the next steps!
Hope this discussion may help others over the setup bumps.

Hope this discussion may help others over the setup bumps +1 on that. Glad you got sorted.

On the collective screen your servo are not suppose to move with the transmitter. It's putting the servo at full throw and you adjust with the slider to give the Heli 12 degrees of pitch. Same with the cyclic. There are times your radio will not work during the software. This is normal for setup and all of the fbl units do this. If you need more help let me know I will be glad to help through the setup.

I'm getting there! I made it through the entire setup program. Probably have to go back through it a couple of more times to make sure I have everything as close as possible to correct.
One problem that I see now is that after completing the setup the tail servo will only move a very small movement with the tail stick. Maybe a couple of degrees. Not sure what might be causing that. I set the travel limits on the slider and checked direction and that all went pretty smoothly. I'm sure something isn't right just not sure what it might be.
Again, any ideas?
Curt
Also, what color is the status led supposed to be after the BW finishes booting up. Mine is red, suspect that isn't right. What might it mean. Tail slider doesn't move perceptively when rotating the heli either.
Sorry for all the questions but I'm going to get this setup if it kills me. It starts eating at my old brain.

Got my tail issue sorted out! I went back through the setup software and adjusted the travel endpoints for the pitch slider. I had just left them at the program default as there was no interference with those settings. I guess that was the issue with not having control of the tail pitch.
Then I went into the gain adjustment for the gyro gain in the DX6i and adjusted the rate setting for 45 and the HH setting for 65 as starting points. Now the BW status led is red while in rate and blue while in HH. The tail slider is moving while rotating the heli also! YEAH!
I'm getting close to feeling comfortable trying a test hover.
Again I hope my confusion may help others with their confusion.

Woo Hoo!
Just came back from doing a few test hovers with the BW conversion. Didn't bring her back in a laundry basket! The collective was real sensitive and I adjusted my D/R until I felt comfortable. The wind was blowing pretty strongly so wasn't a real good test but, the tail seemed to hold real well.
I'm excited to get her out again and do some more testing. I'll post updates. Thanks again for everyone's help.

That's the first thing I was looking for. That is how well the tail held because the gyro used for the tail is more than likely the same as the other 2 controlling the cyclics so if the tail holds good the head should also be good. I found mine to be rock solid and I still got a lot more tweaking to do.

I notice guys say thy need more tweaking. what are you finding that needs tweaking. Just curious and trying to et other opinions on the unit.

I have found that the mounting tape that comes with the gyro is too loose for the gyro. I have been using the clear gel tape. Or use the gray 3m tape. One layer on electrice, two layers on nitro. Going with the tigher mount has stopped some pitch up issues i was having. Barry

James I'll know more about the tweaking after a session tomorrow morning if the weather cooperates.
I remounted the BW with thinner tape tonite and checked the balance on the main blades.
Being a newbie at this FBL technology here is another question. I'm assuming that the two pots, on top of the BW Ele and AiL, are for gyro gain on the Elevator and Aileron. What should I be looking for that would indicate that the pots need to adjusted?
Wish me luck tomorrow.
