I bought a phantom 2 and added a walkera G2D gimbal.
It is OK to use and setup WITHOUT any remote pitch control connected from the Naza controller to the Gimble, as I have found that the signal on the pitch control line from the Naza system varies as the Quad is tilted (it uses the Quads levelling system signals) SO what we get is a 5 degree forward tilt on the Quad gives 10 degree reverse tilt on the Gimbal, the movement is doubled. Great Aye. I will check later if this feature' can be turned OFF in the system assistant, possibly the FPV check box.
But if you want to continue ... read on...
I fitted the Gimbal to the underside by drilling 2 small holes for the T shaped mounting plate and using 2 small nut/bolts
It looks like you have a mounting plate that fits the 4 mounting points at the front of the Quad, but does the Gimbal mounting plate fit this?
The Gimbal and camera can take power from the 4 way cable shown in your picture, download the phantom user manual V1.4, it has some wiring diagrams which mention this , fig 1.6,
You have green lights on the gimbal before you have the power lead connected because you are taking all the power for the gimbal through the control line...NOT good !! , the motors when powered on can take 300 -500mA !! and may damage the Naza controller
Use the provided lead I mentioned above, the positive is red and negative is a brown. Both browns are connected to battery negative (ground/common) so either one.
I bought off ebay/amazon a few wire ended 2 pin short power leads that fit the red power socket coming from the gimbal lead and also couple of 2 pin Y type power leads that have a socket to two plugs (the spare is to power the iLook camera I fitted) .
You need to solder, or get someone to do it (not just insulating tape!) the red lead of the flat 4 way cable to the red lead of the wire ended power plug and the brown from the 4 way lead to the black on the 2 way wire ended power plug.
You MUST insulate the bare joints with heat shrink tubing or if you don't have, use the wire insulation from a piece of mains flex, but make sure the inside diameter would be wide enough to pass over the individual soldered wires and place over each wire before soldering.
The extra cable is pushed up inside ..You will need to take the lid off the copter to lay it neatly.
The Y cable is then plugged onto this new termination and one of the other connectors is plugged into the gimbal power lead.
The Gimbal has its own self levelling circuit on the back of the camera plate which keeps the camera platform level. Assuming you have a camera fitted to balance the gimbal, as it wont work without!, AND you have double checked your soldering RED to RED and BROWN to BLACK ... you will FRY the Gimbal controller if you have soldered the power lead in reversed!!!
First without any pitch and roll control leads fitted, power up the TX and then the Quad on a flat surface. The Gimbal leds in the controller will flash red for a few seconds the go solid green.
The platform should if everything is balanced, point straight forwards if not been offset on the V1 and V2 adjustments on the gimbal.
If you pick up the Quad and tilt it around, the platform will respond by tilting the opposite way to keep the camera straight and level.
Now for the annoying bit I found out after doing all this. I fitted a control cable from the Gimble pitch connector to the Y2, I personally do not like supplying power to a device via more than one route, ie the control cable red centre wire which I cleanly cut a 5mm section out and insulated it with tape. You only need a ground wire (black) and a control wire (white) to operate the camera pitch.
I used a separate battery for the gimbal at first and didnt want any voltage from the flight battery, it would have joined the remote battery positive with the flight battery positive which may be at different voltage levels causing possible undesired heavy current flow, thus I needed to cut out the control line positive wire..
Once this is connected , repower the system, you will find the camera platform now overshoots and wont stay level as before. Roll is still ok.
Hope this gives you an insight into powering & using a walkera G2D gimbal. |
