"Yes, mu metal would reduce the earth magnetic field that you want to detect, but you would have to completely enclose the compass in mu metal.  You place the mu metal between the compass and the source of the magnetic interference."

Drones in the news - a Whitehouse petetion

The story, which I copied verbatim:A Minnesota brewery's airborne solution to the preventable yet apparently prevalent problem of running out of beer while ice fishing has been shot down by the FAA. Lakemaid Brewery's clever use of a six-rotor drone to whisk the frosty brews to their icebound customers runs afoul of the agency's current ban on the commercial use of unmanned aircraft and it didn't take long for the operation to be grounded. “We were a little surprised at the FAA interest in this…See More

Prop Clearance

Posted on October 18, 2012 at 8:32am 3 Comments

After a crash, two of the arms on my 3DR Hex shifted slightly.  Enough that the props overlapped.  I didn't notice it for a while, but on a subsequent flight, they prop tips touched.  The hex didn't crash but the noise it made certainly got my attention.

My solution was to add more sonar mounting brackets to beef up the arm placements.  It also gave me more places to mount stuff.  (Copter is upside-down in the photo).…

Prop Removal Tool

Posted on September 28, 2012 at 4:30pm 3 Comments

I seem to be removing my props often, and I worry that my hand holding the motor while I torque the collett on or off is not strong enough and I certainly don't want to use a steel tool like a Channel Lock.  So, I use a small plumbers strap wrench, pictured below.

This one is overkill because it is made for, well,…

Totally understand, and I agree updating the post to explain the optical illusions, for want of a better term, is a best option in my opinion.

Good work on the other blog posts. I am new drone creator. I have gone the ArduPlane route with a Bixler. Haven't flown it yet, and it's broken. The joys of hobby electronics, though this issue is mechanical and one of the servo couplings for the aileron has broken. :-D

PS: to be honest, the wikis could be much better in describing how to set-up these boards, especially, if like me you are just plug and play and not necessarily wanting to look at eagle files and schematics all the time. Maybe you could update the wiki to add the GPS connection for APM2.5?
