Dual GPS auto switch?

Hi there, I have been running dual GPS's since I found out that the support had been added. But I have not seen anything in mission planner, or a log to say that the GPS switch is actually happening.…Continue

Pixhawk Airspeed Sensors for multirotors

Hey everybody,I was wondering if anybody knows whether or not you can use an airspeed sensor with arducopter. As I understand it, with arduplane, the airspeed sensor acts like a barometer as well.…Continue

Please tell us a bit about your UAV interest
I have just recently been introduced to the world of autopilots. The only things i had flown in the past were old school rc helis, and planes. Looking into starting a business doing aerial mapping, and a bunch of other things to do with drones.

Hi Craig,

Not sure how to use 'friends' yet so I am replying here.

It looks like we are doing similar things. I have four X6s which I intend to use for aerial mapping (I am an academic and I will use the photos to produce digital elevation data). I decided on the X6 because it is relatively easy to transport  - two of mine are en-route to Turkey as I type.

It is all a bit frantic as I am doing this for the first time. I have been flying the X6 in manual and have now mastered a bungee take-off to minimise damage to either myself or my colleagues! 

I will try your suggestions for TARANIS setup later in the week. I also need to setup the mapping camera for the first time so that should be fun. I have two Sony NEX5s but will probably start out with a canon SX260 I picked up cheap.

Hi Craig,

We had quite a few problems trying to find the right motor/esc combination. I had some powerful but low KV motors (750 and 850) which were unable to successfully launch the X6. In the Turnigy SK3 3542 1000kv motors from Hobbyking. 

The bungee is a modified Hobbyking peddle launch affair, with the longer 10m bungee cord. My X6 weighs 2.5Kg with the camera (I have this in the rear compartment and I cut out a hole in fuselage and lines it with drainpipe) and for this we needed 12.5kg on the bungee cord which equates to ~50m. It seems to work well. 

I mounted the z shaped hook in plywood sunk into the rectangular hole in the bottom of the airframe.  This seems to be OK although I have not yet finalised the angle of the hook as sometimes it gets a little stuck and the X6 banks when power is applied (I do not apply full power until the hook is released).

I am using a 4S 5amp battery battery in the front compartment which at 600g offsets the camera in the rear. I also modified the motor mount, using a 6mm plywood sheet rather than the plastic thing supplied with the kit. I use a 60A ESC as the motor draws 38 amp on the bench at full power and I like to have significant headroom. I am using a 10x6 folding prop but the marginal power for launch is pointing more to a 10x5. I doubt a 9x6 would do the job.

I am hopeful of getting a full autonomous mission completed over the weekend as I am running out of trial time - I leave for Turkey on July 7th and will be mapping two days later.
