DIY Wire Rope Isolators
Thought I would have a tinker with Wire Rope Isolators.
After a number of prototypes this is what I have come up with so far.
Using:
1x 40mm PVC pipe cap. Cut down to 1cm.
1x 50mm PVC pipe cap. Cut down to 1cm.
1x length of 1.1mm Wire Rope. The same cable they use on bikes for changing gears.
I tried 1.6mm and 2mm wire rope but found it too stiff for the weight of the Gopro.
I will post a video shortly with the results.

Its 3m Dual Lock. Its super strong. I use it to attach my mounts to my Quadcopter. And have to use a screw driver to pry it off.

New Version
My new light weight PVC T-Quad.
I have moved the battery to the top, and the flight controller to the middle. To get the CG up higher.
You have to cut out the middle with a dremel to get every thing to fit. Structurally it still feels very strong. Will find out when I crash it next.
Still with 20mm PVC pipe and T-adapters.
Arms are 20cm, Motor to Motor is 480mm.
Hardware:
Flight Controller: DJI NAZA Gains: 125 125 125 90, attitude 95 95.
ESC: CarbonBird 18a, these a super compact and fit in the 20mm PVC arms.
Motors: Turnigy NTM 28-26 1200kv
Prop adapters: NTM prop drive 28 series
Propellers: Gemfan 9x4.7 (Nylon/Carbon Mix)
Battery: Zippy Compact 3s 4000mah 25c
Weight:
With FPV gear (Without battery) 903 grams.
With FPV gear (With battery) 1190 grams. Hover time 15 minutes.
With FPV gear & Gopro camera (Without battery) 1134 grams
With FPV gear & Gopro camera (With battery) 1420 grams. Hover time 12 minutes, Flight time 8 minutes.

Gopro Rotor Shade
This helped me eliminate the horizontal lines you get when the sun shines through the propellers onto the Gopro Lens.
It can only be used when the lens angle is set to "Medium" though.
I used the bottom of a plastic container to make it.

So after carting up all my gear to the top of the mountain. I found that I forgot to bring my video reciever power cable. So had to film LOS on this footage. Next years will be better.
Keeping my batteries warm prior to use made a big difference in flight time. I stored them in a insulated fabric wine bottle cooler.

Great job Matt, at the end of your test, which version and setup do you recommend ?

My latest version seems to be working well. Putting the battery on the top has made it more stable. I think it is giving the flight controller an easer job, with less weight hanging from the bottom.
Also upping my gains has help too. They were on 95 95 90 90.
I'm happy with my current setup. 8 minute flight times is plenty for what I want to do.

To get a Basic "Line of Sight" PVC T-Quad it would cost a minimum of:
Dji Naza Flight controller $250
ESC Speed controllers x4 @$15 each = $60
Motors x4 @$15 each = $60
Propellers x12 @$2 each =$24
Power distribution board x1 =$7
Basic radio $70
Batteries x3 @$25 each = $75
Battery charger $50
Materials to build PVC T-quad $50
Total approx $650
To add FPV equipment it would cost approx:
Fatshark goggles $300
FPV camera $70
FPV transmitter $40
FPV receiver $40
Total approx: $450
So all up approx: $1100

Thanks. After 6 months of tinkering and plenty of flying, I'm finally getting the results I was aiming for.
