LOS flying and orientation tips

jkosmidesjkosmides Club Members Posts: 10
I fly LOS and found that adding 2 bright LEDs on the front of my 250 helped a ton when it comes to staying oriented and knowing when the quad is pointing at me. In my case, the LEDs are close together but I can see how getting some separation between them would help even more to discern orientation.

I'm wondering if there are other tips that LOS flyers could suggest for staying oriented and out of trouble?

    I dont quite understand how adding two LED's can help when you fly FPV and so far away that you reach LOS (Loss of Signal). For my opinion only proper programming the failsafe option of your FC can help, when you loose signal and no LED's...!

    Here again we can see what acronyms can do to you:

    Edit: What the OP could try are 4 LEDs instead of two - a pair of green at the 'front' and a pair of red at the 'rear'. If he sees red, it's flying away and green means it's approaching. Green/red is the right hand view and red/green is the left (I think - I could have got that backwards) Daithi2016-07-11 05:57:14

    Bloody hell! How about sticking with something more traditional and therefore less forgettable? Port is left and signified by red, starboard is right and signified by green. I would think 2 red on the left and 2 green on the right. Same principals as Daithi mentioned for discerning coming or going, much less confusing to work out which side is facing you though and more natural to both you and anyone else familiar with the old port and starboard light system.

    I put white lights on the front and red on the back, it's easy to remember because I drive a car. These at the front aren't bad

    @Daithi "Johann - 'LOS' is 'Line of Sight' - not signal loss "

    If I look at the page, I can find this:


    Loss Of Signal Computing » Telecom -- and more...

    And this is why I am programming failsafe correctly in case of having a LOS. image jstremmler2016-07-11 15:09:17

    Juergen ... in this context it is Line of sight. Read the very first sentence the OP wrote:

    "I fly LOS...".

    Now he is hardly likely to be flying Loss Of Signal now is he!

    I use two super bright White LED's on the front and Two super bright Red LED's on the back

    Green on one side and red on the other as in Ships navigation will only rise to confusion

    So green left is facing me and green right or is it gowning away or is it the other way around ?

    White its facing, red its going away is much simpler to remember in a panic

    Actually according to an acronym finder LOS in order is

    Level of Service

    Lines of Supply

    Law of the Sea

    Line of Sight

    Loss of Signal comes down about number 6 in that list

    It can also mean Linux Operating System or Late Onset Schizophrenia image

    In this case it's definitely Line of Sight image

    Finally we have the profound discussion I like so so much! image So finally let me make my profound contributions. I configure my Naze32 with the CLI command: set failsave_procedure = RTH. Next I configure Failsafe in Cleanflight to Throttle = Hold and the Aux Channel for the flight modes to pulses which initiate RTH flight mode in case of a signal loss. When I now fly LOS (loss of signal) and my multicopter looses its RC signal my Copter safely returns to home and lands. And believe me, I don't need LEDs for that....jstremmler2016-07-12 12:32:38

    Whoopee bloody do ... And that comes under the 'FOS' heading in the context of the original post. image

    Was referring to Law of the Sea. I fly off my boat over the ocean. :) image

    I tried the port starboard setup and found it hard. Front and back work much better.

    Spedix is great with green/red LEDs under each motor and then use same colour props.

    One directional light facing out front can help too, esp when learning. Good at dusk too as it shows where you are on the field, just don't make it too bright or it just blinds you.Chainsaw Urnuts2016-08-04 04:50:52

    I suppose if the end LED on each strip was curled around the corner at 90 deg. that would give an indication of direction when flying side on - or can the front & rear LEDs be seen from that angle anyway.

    I am about to plaster a few over my old quad so I can become more adventurous.
