Arduplane with second pixhawk

Would like to setup a second pixhawk that would crash the plane (full down elevator) if for whatever reason the plane has deviated more than 100 m buffer from the geofence set on the main pixhawk.

 This is for additional safety and would also ensure t

29inch Quad U8 motors

A small clip from the high efficiency quad using 29 inch 3 blades props running of U8 135KV motors and 6S batteries.

 The setup delivers ~35 min with 16,000 6S lipo and 1.8 Kg useful payload.

 More scope for extended endurance beyond 40 minutes with la

Re-establishing telemetry

Often I would loose telemetry and it is not possible to re-establish the link while the system is flying.

 Especially with auto missions it is rather frustrating if the system goes out of range and then there is no telemetry for the rest of the flight

Ch7_OPT equivalent in arduplane

Hi,

 I am trying to setup CAM_TRIG_DIST in arduplane but there is no CH7_OPT available.

 My device, an arduini mini, works fine if I use signal pass-through to the axillary channel but it doesn't get triggered with CAM_TRIG_DIST.

 Thanks

Hyperspectral imaging

Hi,

 Can anyone recommend a decent hyperspectral sensor that wouldn't weight more than 2-3kg including the data capture/storage unit.

Pre sales Customer service from a couple of manufacturers is rather appalling, they must be making a fortune.

broken Mavlink on Arduplane -PX4 pixhawk

It seems that once I upload arduplane on my Pixhawk I can't get to communicate over mavlink in mission planner. Firmware loading seems to work OK.

 If I upload the PX4 firmware via QR I can get Mavlink in mission planner but I want to upload the ardup

One UAV multiple ground stations

Hi,

 I am interested in using multiple ground stations for one arduplane platform.

 This could be for example 2-3 computers with radio telemtry and mission planner.

 The idea is to be able to have a person that can dynamically give a command to the Ardu
