Yeah, I understand that, would like to have some idea of range. 1 mile, 2, any idea, even on just line of site.

Comment by John McGrath on December 10, 2013 at 8:43am

@tomgates They are correct your mileage will vary depending on terrain.

Anybody know what approximate range of the FlySky transmitter and receiver is with 3d robotics quad?

3d Robotics tells me the telemetry on board is good approximately a mile, more or less, given the terrain etc.

Hey everyone.  Just got in a second quad power distribution board in today and want to turn my quad into quad-8 or Octoquad.

I purchsed a second pdb thinking I can use it to power the additional motors.  As I look at the quad and octoquad motors setup I see that the quad motors 1,2 are diagnal for the quad but are clockwise on the Octoquad top motors and 5 trhu 8 for the bottom motors clockwise.

Long story short does anybody have advice on using 2 quad PDB's to make an Octoquad?

Finished my GoPro anti-vibration mount last night , waiting for weather to behave so I can test it out. I left the big plastic thumb screw in place until I decide what angle I like , my fat shark Predator V2 set will be here friday!!!! 

Heres the Circular polarized antennas I built today based on IBCRAZY's design!

What advantage is there to installing sonar to the APM Copter. Is it a worthwhile option?

Comment by Mike Wilson on December 2, 2013 at 10:01am

@Tom Gates,

You can check out Pelican Cases.  I'm sure they have one that will fit the bill for you.

3d Robotics Quadcopter-Ground Control Case

Ok, I now have my 3d Robotics quad, telemetry, OSD/FPV, etc.

I would like to have a hard case to carry my quad in and another to put laptop in with all the pripherals, so when I get onsite I will have limited assembly to make ready for flight.

I am not seeing cases big enough or deep enough for the quad with the camera mount extend legs, I could make one, but thought surely others have been there and have good suggestions.

Thanks in advance.
