  Hi,

  How can I reverse the control surfaces on pitch,, roll works right,, i need the change just pitch,   I am controlling by joystick

  @ tomi.

  By checking or un-checking the "reverse" boxes on the radio calibration page it will change the "autopilot control without affecting normal pass through control. I had the same problem.

  Hi, I am new APM plane user,, I got my new APM 2.6 , I use it on flying wing,,   on FBWB mode the movment of control surfaces are not correct, Does anyone know how to set ,

  Thx

  Geofencing = uncrashable mode??  So, I just got my APM 2.5 up and running.  So far, I have used Stabilize, Training, and Loiter.  And it was awesome!  I have some kids AND friends that would like to learn to fly.  I can't help but notice that training moder is GREAT, but I want minimum and maximum altitude limits, as well as roll and pitch angle limits.  This should prevent hitting the ground or flying out of sight.  Is there any step-by-step stuff for setting that sort of thing up??

   

  Thanks,

  Tim

  talking about swinglet, I really dont like their commercial strategy, so expensive.....

  Hi Frejus
  
  I am having a flying wing with 11m/s cruise speed. With chdk and a fast SD card you can get a picture every 2.2 seconds with a canon SX260 in shutter priority mode.
  
  I chose the flying wing design over a traditional design because it sustains mich Harder beatings. We are operating our UAVs in rough terrain so this is more important to us than efficiency.
  
  Hope that helps

  hank you guys.

  @Mike : yes I am aware of this company in Lausanne but they are using their own proprietary techno while I want to go for standard stuff only. I believe their wing has much physical appeal + transportation advantages but could be easily topped in terms of flying and stability by any cheap plane in the market.

  @John,

  You are right about the 10 years old APN. I am now diving into a Skyhunter vs Skywalker vs Easyglider comparison so that I can indeed replace the Canon APN with some neat Sony 5R + quality lens and board 3x 4S 5000 ma battery.

  80 minutes flight / 50 miles seems now a reasonable target to reach, right ?

  Check the Swinglet YouTube channel: thei just published a mission of doing orthophotos of the Matterhorn in Switzerland for mapping purposes. Pretty awesome. Their wing is quite small and light to be compliant with Swiss legislation.

  It's less a matter of what kind of flying support you use for your camera than the post-processing process to take full advantage of your pics.

  You will find people using fixed wings (swinglet, X5, X8, etc...) you will find people using planes, from 1.4m wingspan to 2.5m and probably even more, you will find people using a quad-copter or even a helicopter. It depends on how you want/are able to take your pics, but mostly of how your pics will be post-processed.

  Personnally, I took pics with quadcopter and a sports cam (gopro, lic ego, Magicam) for evaluating hog damage in corn fields. The fisheye lenses didn't allow for precise mapping, but it was enough for the task at hand.

  Hope this helps.

  Frejus... You need to use quality camera gear not some 100 dollar 10 year old cannon. The times your camera is able to take a photo and recover is dependent on the camera. If CHDK is an issue its easy to change the script you use.  Speed should not be a factor in this sort of photography. If you want to rush down the farm field and snap snap snap you will not get results it has to be a mix of everything to get optimal results.  After all this is the SR-71.  RV Jet,  X5, X8 Skywalker 1900 or whatever plane you use is sometimes more preference than anything. But if if you need payload, long fight times you start to limit the choices especially at the 60 minute and up mark in the hobby realm of purchase power.

  The more I read about wings, the bigger my doubt...

  I mentioned orthophotography, and speed is not so good.

  As a matter of fact, slow speed is required for being allowed to take more pics in a certain distance, meaning a higher final definition.

  Let's say an APN + CHDK can only take full definition pics every 3 seconds.

  The distance when flying at 20mph and 60 mph is 3 times less, meaning accuracy can be way better. For that very reason I believe a plane is not as sexy a look but would allow for fantastic slow flights.

  Now how is speed correlated to ability to perform during high winds ? Any specialist ?
