  Hi,

   

  is there information available on the lift characteristics of the arducopter propellers? I am looking for information to use in a theoretical calculation where i am able to relate lift to rpm.

   

  thank you for any information

  I'm sure Chris will have opinion, but since he's not a lawyer, he'll probably not want to give us a legal opinion.  The laws are simply not caught up with the technology yet, and if we all operate our Arducopters responsibly, there will be no need for any government to have to pass laws to limit our use of them.

  Many people are currently using Xbee radios for telemetry that are capable of communicating with a UAV beyond visual range.  Using a cell phone would just be an alternate way of implementing the telemetry link (albeit with the potential for MUCH longer range telemetry). It doesn't change the fact that it would still be up to each user to be aware of laws in their area.  Having the capability for the UAV to access data from the internet, such as maps, or other databases might allow for some really cool features.

  @Dara Shayda

   

  Very interesting reading Dara.  Thanks for the links.

  According to this excerpt:

  How unmanned air vehicles are different from model aircraft

  "Model aircraft" means an aircraft, the total weight of which does not exceed 35 kg(77.2 pounds), that is mechanically driven or launched into flight for recreational purposes and that is not designed to carry persons or other living creatures. Although some micro unmanned air vehicles may weigh less than 35 kg, they are operated by research institutions and other organizations for non-recreational purposes.

   

  In Canada, we fall under "recreational purposes".  If I plan to run Arducopter in a non-recreational purpose, I need to apply for a license.

  That very clearly states that if it's for recreational purposes, it's not a UAV, and therefore all the rules regarding UAV's, including the need for an SFOC, do not apply.

  @adli: at least try to read the manual please

  How about looking at a screenshot?

  @Dara Shayda

  If you want to have a better idea of how to control the drone with a cell phone (Android in this case), check out what is being sold at the DiYDrone store:

  They are calling it the phone drone.  There are no legal issues with using this.

  @Dara,
  Ibelieve you misunderstand the drone cell issue.
  No one is creating a signal interfering with cell freqs... This is legitimate cellphone equipt using the same specs and protocols, and they work with the national cell networks with no problem; the digital signal represents the R/C commands no different than your smartphone or computer.

  @ Ellison Chan,

  You are right about the use of the phone drone system, but as for spectrum amanagement you are a bit optimistic about the FCC mandate, their powers, and possible penalties.
