"Hi Carl, what is the total wing area of your aircraft? At 5 lbsTOweight a good start would be 600 to 800 square inches."

"From a commercial aspect, insurance in the $2000 to $4000 per year does not seem unreasonable for basic operational requirements of a serious UAV business venture and getting a $2M liability policy. It is a real and important cost of doing business…"

"I know that I have found a number of his posts helpful as well. "Liked it"! There are lots like him here, but we need more like him here on this forum!! Fly high and keep the Gyros level Al!"

"Jonas, I have seen this happen when I forget to switch the switch on the APM board to CLI mode.   Does this help? Downloading log files First, ensure that your slider switch is in CLI mode (towards servo rails) and that you've…"

"Looks very clean and easy to keep orginized.  Well done!"

"This is absolutely critical and is the key to unlocking the real potential to doing some serious mapping with the AruPlane. In addition to the above requirements, I would add that the trigger routine, would be very useful to have multiple routines…"

"That was easy!  Once you get the "intuitive interface" figured out!!!"

"So, this brings up an interesting point. If I were to use APM2 as the basis for a commercial product, what requirements, licensing, waivers etc do I need to follow in order to resell the APM, Mission Planner etc to a customer? I am not talking about…"

"Sorry to hear that mate!! Thought it was going to be a winner with your set up. With this hobby, there is always a failure mode waiting that comes to the surface.   Have you thought about that big black Flying wing that is on…"

"Looking like a fun build.  Would you happen to know the exact weight of the airframe as delivered from HK? As usual the sight does not give the actual weight of the aircraft. I have been thinking about one of these airframes as a FPV aircraft,…"

"Grips, as mentioned you can check the site that Ellison mentions as well. The correct underwriter that knows the industry is key. I would suggest loydds of london, and Marsh or Aviva. Lots of others will do UAV's but you might need to educate…"

"First of all, regulations are good as long as they are built and used in moderation. I have found that the SFOC process currently used in Canada is straight forward and logical for commercial operators to safely operate UAV's for commercial…"

"I have been using ABS plastic sheet for many of my UAV designs for a couple of years now and it cuts great on the laser.  It does stink though when cutting, so I would recommend using a carbon filter for the exhaust. It cuts great and is quite…"

"I wonder if an e-ink display wouldn't be better, since it only uses energy when it is changed, so it would not need to use energy during most of the flight, during which the display is unlikely to change much.... Spark fun has them. It is not…"

"Thank you for the quick replies.  I thik that the idea that Martint showed will work great for the basics. Eventually a display would be the crowning achievement, but for now a few flashing LED's will work for me!   Thanks for the…"
