FPV wiring Diagrams

[Coyote]

Hi lads, I thought I`d start a thread on the diagrams I`m making. This first set is for DOSD. After a potential problem was discovered recently these new diagrams will enable you to wire up the DOSD perfectly safely avoiding the potential problem.

Ok first the most common application :

Easystar Basic

Spec :

3 Channel control, Throttle Rudder and Elevator controlled by DOSD
FPV system isolated from ESC circuit
12v Camera
12v Vtx
Dragon Link UHF

System supports : Gps based flight stabilization, RTH with speed control, programmable missions capable



Delta Wing Basic

Spec :

12 v Camera
12v VTX
Isolated BEC circuit.
Isolated ESC Circuit
Fully filtered ( Camera, OSD, Vtx and Bec Circuit )
DOSD Powered of filtered current sensor wire and jumper
BEC supplies PWM 4 ( not used )
Only signal wire from ESC used

Completely safe

Note : The shielded wires are not joined at the BEC, this stops a ground loop, both wires going to BEC are part of the shield system though



Twinstar setups :

System 1 : Basic 4 Channel Setup

Spec :

Full Aileron, Elevator, Rudder and Throttle control via DOSD
Camera, Vtx and BEC Filtered ( Bec`s not needed but easier for wiring )
12v Camera
12v Vtx

Completely safe.
Isolated FPV circuit from ESC`s

System supports : Gps based flight stabilization, RTH with speed control, programmable missions capable



System 2 : Twinstar with IMU and Mic

Spec :

Full Aileron, Elevator, Rudder and Throttle control via DOSD
Camera, VTX, Mic, IMU and BEC supply Filtered

12v Camera
12v Vtx
12v Mic
5v IMU ( Optional )
Step-up for Camera ( Optional )

Completely safe.
Isolated FPV circuit from ESC`s

System supports : Gps and IMU based flight stabilization, RTH with speed control, programmable missions capable, aritificial horizon

Skywalker system

After the ground loop potential problem i went against my norm and decided on a 2 lipo system. Power and Video

Spec :

Seperate Video and Power system
Seperate standalone BEC circuit
No modification to DOSD wiring connections other than no -ve and +ve from Esc`s Bec wire
Should be no need for any filtering
2 Voltage readings, 1 for video 1 for power

Full Aileron, Elevator, Rudder and Throttle control via DOSD

12v Camera
12v Vtx

Completely safe.
Isolated FPV circuit from ESC

System supports : Gps based flight stabilization, RTH with speed control, programmable missions capable

This is great , Thx.
Now if I want to add pan and tilt to the camera can I run it straight to GLrx free channels, lets say ch5 and ch6 and omit OSD??

Coyote:
I'm busy working on the wiring for my wing with DOSD, with exactly the same setup as the Delta Wing Basic. Just a question regarding the current sensor wire: The standard wire that comes with the DragonOSD current sensor, is not shielded. Will that be a problem, and should I modify the rest of the shielded wires in some way?

For the other items, can I use USB cable as a shielded wire, or what's the best way to get them shielded? And the servo wires?

You could do yes

No the original wire is fine, yu shouldnt have any issues

This looks great Coyote. Do you have any pictures of some of these wiring setups in a plane? I use a Remzibi and have recently added a current sensor as well and had a rat's nest of wiring before the sensor, now it's worse. I'm about ready to tear everything down and rewire the entire setup and heat shrink where possible to try and reduce clutter in the wiring bay. Every time I fly I flex a wire somewhere in the OSD system and once every couple of months or so am debugging a loose connection on a multi-strand wire.

Any ideas for reducing wiring tangles would be welcome.

A diagram of an actual plane with everything positioned and routed ?
