WIRE between LEGS to PROTECT CAMERA

[flyingtim]

Good or bad idea?

I've seen acrylic and carbon fiber plates to fit between the legs to protect the camera.. etc

Has anyone tried wire? or chicken screen? etc...

My PV2 is on the way and I want to be sure I have all possible safety features attached before flying.

Thanks

It might have negative effect on compass if the mesh has ferrous metal in it.

 

[flyingtim]

Yes. Aluminum maybe?

 

[Damon]

As much as it costs for Phantom, why not spend a couple bucks on carbon fiber or lexan braces advertised on this forum? It just seems better to have something a little more rigid instead of mesh.

 

[flyingtim]

Yes, I agree. Just pondering simplicity. And trying to consolidate all the scattered good ideas everyone is trying.
Also, with all the talk on crashes, I was trying to think of something that would be less affected by prop windflow or simply the wind itself.

 

[Damon]

With the braces laying horizontal under the body of quad, lift wind really does not hit them. The directional wind does not appear to have much effect since it is laying flat.

The mesh in theory would have less drag but the protection would be less as the legs would flex inward on impact allowing gimbal to get hit pretty hard anyways.

And when you tilt the camera straight down you get to see whatever you put there.

 

[flyingtim]

well said Damon. good point skulltronix.

Great idea Steve.

Someone asked about using fiberglass instead of the more expensive carbon fiber.
I found this comparison article: http://gwcomposites.com/carbon-vs-fiberglass/

Of course any hard land with 'shock' the system into damage.
But, for those gentler landings over a small stump, branch, bottle, rock... either would be fine is my guess. Or any other non-ferrous metal or plastic that does not break easily.
Weight will be close. Carbon fiber might be lighter because its strength lets a person use a thinner piece.

INTERESTING : "Carbon fiber also blocks radio signals while kevlar and fiberglass do not."

Interesting video showing what a carbon fiber cellphone case does to signal:

Does anyone know these frequencies:
1. The controller
2. The cellphone wifi
3. The cellphone towers 4G
4. The cellphone when just using towers for calls.
5. The V2+ signals for controller/wifi

I'm trying to research out if any signals can conflict with the others. Also if things like the added carbonfiber can be affected by any, or any combinations. (and if this is causing fly aways)

(09:03:42) Tim: Hello
(09:04:24) Tim: Are you familiar with the different signals the V2+ and the controller are using? The hertz etc...

(09:06:24) Serina: The phantom 2 vision plus comes with a 5.8Ghz remote control.
(09:06:31) Serina: The reason why the phantom 2 vision plus comes with a 5.8Ghz remote is that the phantom 2 vision plus has a built-in 2.4Ghz wifi for video transferring.
(09:07:07) Tim: OK. Do cellphones all run on 2.4ghz?
(09:07:43) Serina: Yes
(09:08:39) Tim: Should 4G or 3G be turned off when using the V2+? Also should all tower frequencies be turned off when using phone with the quad?
(09:10:39) Serina: Agent uploaded: https://v2uploads.zopim.io/2/E/0/2E0FBs ... .thumb.jpg
(09:13:02) Tim: Thank you. That helps some.
(09:13:31) Tim: If the compass goes wacky, will the GPS take over and bring it back correctly?
(09:14:29) Serina: You are recommended to calibrate the compass before fly at each time.
(09:15:45) Tim: Yes. True. But if there was something unknown that throws off the Wifi and Controller signals, or confuses the compass, .. will the V2+ bring itself home using only GPS?
(09:21:31) Serina: If the drone lose control, it will go home when it get more than 5 staellites.
(09:22:34) Tim: OK. Very good. I have been researching why people are having 'fly aways' where they completely lose control and then lose the Quad.
(09:22:42) Tim: Do you have any other insights you can share?
(09:24:32) Serina: You are recommended to read the user manual before use it.

yes

i saw all of the carbon fiber mods and where they put their arms to protect the camera. which, arms's locations, they have calculated in advance, and which will not impede the camera's view at all of its viewing angles.

but im just going to use.....DENTAL FLOSS STRANDS!

strung from point-to-point between the landing gear. and so as not to impede the lens viewing angles.

fishing line would be another option.

whatd'da plan to crash into??? a razor blade?

no. a tree. or light pole. or building structure. or rocks on the ground.

none of which will break the elasticity of dental floss or fishing line. these items dont affect GPS.

i dont have the "design" yet. i want to make 2 rail lengths that will mount parallel under the existing landing gear mounts, and, which will give infinite lasso points for floss or filament line to go back-and-forth at the correct places and angles so the camera view wont be affected. and to which, well, you cant string as much as you possibly want/need...the weight is a mute point.

instead of mounting extra rails under the landing gear, you could just drill into the existing landing gear struts 6-8 small holes then lasso everything tight.

its a linux idea not a MicroSloth one...its open to all!

Be sure you share pictures with us.

 

[flyingtim]

Sounds good. Always share photos if you can of your setup
