Reporting back. Went back to the v12 GCS and v3 Bootloader. Re-ran Vehicle setup and wa-lah. Motors have MUCH more pop to them. So I threw blades on, went out for a quick test. Everything really pretty locked in...hovering about 4' off ground...failsafe! (I assume) and right before hitting ground it came back to life (softened blow) but had tipped just enough to land on prop #2...bust!

So, one problem down...on to the next. :)

- What might cause the momentary power loss? (Dragonlink v2)

That's great it worked!!! I also have DL but the one before v2. Still need to buy the adapters to upgrade firmware. How is your DL Rx antenna positioned?

I have a sanders style mono pole mounted vertically.

 

I read somewhere to only use a 2s lipo with bec to set it up with the DL Rx. (Calibrate, re-ID, bind) I used

a little 370mah 3s lipo with bec to do that process. Would this matter?

As long as the BEC output is 5v, it should be good either way. However, with different input voltages, the output can differ, so check the spec of that BEC. But I don't think that is the problem. Did you have your Tx antenna tip pointed at the quad? Did you have a solid green light on your DL Tx?

Hmm.. interesting. Do you remember what battery you used? Check the battery status with a lipo checker or voltage meter. If you don't know, please, if you haven't done so, do a range check. Enter the DL into micro power and just plug a servo into one of the channels.

hello; what are you folks doing to power your 12V onboard components?  step down or separate 3S lipo?

 

I a currently using a 800mah 3S, and am looking into step downs.

 

Anyone have experience with the Pololu 12V step down? 

The getfpv website says the pololu 12v step down provides 600mA.  Does that mean I need one for each component?
- 600TVL

- 1.3ghz 300mw TX

- Cyclops Breeze

Yes I use them and they work just fine within their limits.  If you need more amps HK sells them too.  

 

There is something to be said for having a separate power source for the FPV gear.  I run two batteries on my 800 Hexa.

It is the camera but without the firmware.. It does not feel sharp enough if that makes sense...

i have the seawolf pixma cam on both my qav400's and i think it is almost the same as the tbs 69 and the Lcu690. I got this to replace the 600tvl and it is much better and i can finally see the branches! i really like how it handles bright horizons.

i used the tbs recommended settings. their menu is quite different but if you look around you can find those settings. you have to go into the advanced menu which is left, right, left, right, down. also be aware that some of the menus have sub menus and submenus

Ive been testin the security cam 2000 sony super had 600tvl and i am extremely impressed with it very crisp colors and good wdr the price is real nice as well like 55 bucks with the case but they get you on shipping 25 bucks for express but youll get it in a few days, i also reccomend the rmrc 600tvl little more pricey at 99 bucks but with priority 6 bucks youll get it in 2 days inside the us and no settings changes required and it comes in a case.

Why not just use the GoPro live out? Its lighter and more simple? That's what I do. Not a problem for me.

Lighter than what? Not a flight cam. I suppose u save some weight if you run the gopro only with no flight cam, but he was worried about accurately being able to see tree branches and such, and the gopros wide angle takes away from that accuracy, but you can change fov on gopro now a days i suppose, but then you gotta worry about your go pro battery being charged and if it dies mid flight you lose video. And it was also rumored not sure if new fw has fixed the problem but the gp3 would freeze up in live out mode, which could also be disastrous.

If you start doing fast flying and flips the go pro isn't good enough

Also gopros introduce noise to an fpv setup apparently...
