@minimad - if everyone is happy with channel assignment, I can make a pull request so it will go to nightly builds.

But still, I can't get the camera to work, and I think this is due to my model profile : It only has 6 channels in "model setup", and the camera works on channels 7 and 8. thing is, I can't change the value using the buttons on the devo, and when I change It to 8 on the .ini file, it still displays 6 on the radio
Any idea ?
Which FW build are you using? I'm not sure if it is in the nightly builds or not. victzh posted a custom build a few pages back...here it is again along with the matching FS files which you may or may not be able to get elsewhere right now. If you're using the correct build then post up your model file for a look-see.
As always, make sure to back up your model, modelico, and tx files before any FW changes.
Thanks Jason, but victzh only posted the 7e version, and when I install this one, my devo 10 gets stuck on the update screen
I currently am using the latest nightly build (ddf6350)and I'll try to mess with other files (learning by doing) until our great Guru named victzh posts the devo10 version
OK, good to know. I was wondering if the updated V2x2 protocol w/ 10 channels was integrated into the latest nightly or not. I want to mess with those trim switches, but don't want to give up my accessory control.

On my 7e set up with your NanoQX model, when I change batts in the quad, if I don't restart the timer, the Tx starts to (or continues to) beep at me. My practice now is to toggle the power switch to restart the timer on the quad battery. Is there a way to restart the battery timer without toggling the power switch at each battery change?
Also, I see in the model setup, a Tx power setting. Default seems to be 10 mW. I think my 7e has been modded to have more output. If it has the "jumper cable" mod, is the Tx output fixed at 150 mW, regardless of the display? Or is output actually selectable, as is suggested by the menu?
And finally - man, I've been going through batteries in the Tx like crazy (seems to me). Two sets of AA's over the weekend. Granted, there was a lot of time in the USB drive, so maybe it's not as bad as I think. Question - if I set the Tx output to 10 mW for every model, will that help my Tx battery life? (which would make this question #2a, since it depends on answer to #2)

A couple of newbie questions:

It does not matter which value you select, it is not adjustable. As PB stated here you should modify the tx.ini.Also, I see in the model setup, a Tx power setting. Default seems to be 10 mW.

No, if you have made the mod the tx will always have full power drawn from the batteries.And finally - man, I've been going through batteries in the Tx like crazy (seems to me).

It looks and seems to be adjustable to me. I have drop-outs with my nQX at 30mW when I go outside, but when I select 100mW or 150mW it's fine.
I think it will only have full power draw all the time if you remain on the stock FW. Once Deviation FW is installed, the diode mod is performed, and the tx.ini file is modified it appears that the Tx power output is fully adjustable.
The bottom right button, or "L-" button resets the timer for me.
One option for the Tx batteries is to invest in some NiMH AA's. I got some super cheap one's on BG, but I don't recommend them. I found a wall-wart in my closet that had 12V 500mAh output and the plug fit perfectly. I leave it plugged in when I'm connected via USB, and between flights, or if I'm flying inside. These batteries really suck, though. I can go maybe 3-4 flights w/o charging before I HAVE to plug in. But, if I plug in b/n every flight and take a small break, I can fly all day. I can also charge the Tx batteries directly w/ my Accucell-6 charger, but I have to remove the battery cradle from the Tx to do that.
I'm also thinking about getting 1 or 2 2S LiFePo battery(s) (6.6v) and modding the Tx so they fit well, and are easy to charge.
www.hobbyking.com/hobbyking/store/__1407...4_Reciever_Pack.html
From what I was reading 1 of these packs will fit with just a little modification, and I think I might be able to get 2 to fit in parallel based on the dimensions. Hopefully, I won't have to worry about keeping the Tx plugged in all the time after this addition.

I also had to go 100Mw on the nQX.

There's my good friend Irv!

Jason made me reinstall FW using the latest nightly build. The install got my sticks straightened out flying the V202/FQ. I intended to save/reuse the tx.ini file. But this is ALL Greek pig latin to me, so I'm not sure what I've got.

Is there something in the tx.ini file that I can look at to confirm .... anything? I will say that the Tx gives me a range of outputs to choose from: 300 uW (I think that's low power), 1 mW, 3 mW, 10, 30, 100, and 150. So if you guys are correct, then I can pick and choose the output for each model.
(man, this is just awesome stuff. I love it!)
P.S. I dialed back output to 10 mW on both Nano and the V202, just to see if I could tell any difference. I have been flying the nQX/FQ in acro mode almost exclusively, so the quad most certainly isn't getting more than about 60 - 70 feet away from me.
And if I may be so bold, I can now say that what I'm doing in acro mode can now be referred to as "flying". (he said proudly) Granted it's still drunken clumsy flying - but flying it is! By Labor Day I should be getting things smoothed out and flying pretty.

I spent an afternoon going through the dimensions of the various LiFe batteries on HobbyKing and finding the optimal one that will fit into the cavity of the Devo7e.
I have finally settled on the 3S Life pack that many people use for the Turnigy 9x.
I will buy two, split it into three 2s packs. Then I will have enough for three Devo7e. For me and two friends.

Now just a matter of placing the HK order to see if my research pans out. LOL
Booo...just noticed the LiFe pack is now out of stock. Too slow on the trigger.

I am far from my beloved Devo

Could you test them for me so I can make a pull request?
Thanks,
Victor.

Great to hear you got it sorted bro!
Yes, 300uW (300 microWatts) is very low power. The power steps are in order from lowest to highest.
If you open your tx.ini file you should see a section that looks like this:
[modules]
enable-cyrf6936=B12
has_pa-cyrf6936=1
enable-a7105=A13
has_pa-a7105=1
enable-cc2500=None
has_pa-cc2500=0
enable-nrf24l01=A14
has_pa-nrf24l01=1
Do you see the lines that start w/ "has_pa"? The pa stands for Power Amp, and if you have it set to 1 then the power amp is enabled; 0 means disabled. cyrf is the stock module (used on your nQX), a7105 is the module for V9xx craft and Hubsan X4, nrf24l01 is the v2x2 module, and the cc2500 is another module for Skyartec which I haven't installed.

Looks like it is back in stock now!

Are those extra 2 packs already spoken for?

I've seen those LiPo batteries that look like the size of 2 AA's placed end-to-end. Do they make that style in LiFe? Seems like 2 of those would work well, also.

victzh wrote: Guys,
I am far from my beloved Devo, so can I ask for a favor. I added proper definition for known constants - Camera and Video to V202 module, and recoded it slightly for better code readability. As I can't test this myself, I am attaching Devo10 and Devo7E recent builds (just in case, I built File Systems as well, if you update from very old firmware, it makes sense to update it as well, just don't forget to backup model files and restore them after update).
Could you test them for me so I can make a pull request?
Thanks,
Victor.
Awesome work Victor!

I will try it out later tonight on my 7E.

I can confirm that the camera, video, missile barrage and single missle are all functioning on victzh's build, but I'm not sure if he wants the mixer 'dest' set to Camera and Video, rather that what channels you defined a few pages back.
Not sure of what I'm meant to be testing.

If you have full control of all accessories then that is a good sign.
