  Is it important to mount the board directly in the center of a quad frame or can it be slightly off to the side. I would like to mount mine about 2 or 3cm off center.

  Tom: that just means that your throttle is reversed on your RC transmitter (maybe you've switched to another model memory?). Switch it and go through the MP radio setup again.

  hello i m new  in this Group ..also at this quadcopter ..

  i receive my ArduCopter Quad v1.1 RTF - i m locking for some one can help me how to fly i have JR-PCM9X but there is no program with this remote only i find :

  http://diydrones.com/profiles/blogs/how-to-program-6-flight-modes

  this is different model of my remote by the Options ..

  if i want to START connect ...

  1- which mode i should use airplane or heli ??

  2- what is the revers and north ??

  3- what should i do in travel adjust ??

  4- what should i do in Flap ??

  5- what should i do in program Mix i have 1,2,3,4,5,6

  6- how can i use the position hold ??

  7- how can i use the GPS ??

  sorry about this all but really i need help to fly my new babe :)  

  Thank For all ...

  See flybrushless.com for other data. The DIYD/jdrones props are not in there, but should give you good comparison datasets to work with.

  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

  Sorry, I did not mean to name drop.

   

  For Canadians they can use these offices to get more info or apply for licenses:

  We will do so since we like to fly for commercial activities.

  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.

  Hello Mr. Chan

   

  Please consult with Mr. Anderson here, I believe you cannot operate recreational UAVs if you cannot see them with unaided eyes as the operator.
