Hey, I had to get my roof repaired, and so I took my quad up for a little roof inspection afterwards.  Worked great.  I reckon you could sell this as a package to roofing companies.  That way they could show home owners how bad their roofs are and why they need repair, and then show them how great it looks when all the work is done. 

I had a blast helping my friend build his hexacopter last weekend. This video includes some tips and tricks. We also had to do some interesting trouble shooting for problem that showed up during ESC calibration that turned out to be a bad soldering job (yep it was my fault!).

Anyway please enjoy a 5 minute condensed version of a fun day building the most excellent 3DR ArduCopter Hexa-B Frame + Motors + Full Flight Electronics Kit.

Having learned the hard way on a few things, I thought I'd put together a little video that shows some tips and tricks with the APM mission planner.
The first time I tried mission planning some things were a mystery, like how do you actually get into auto mode to fly a mission? I found something that looked like a way to do it from the APM software flight data tab, but that turned out to be a disaster because there was no way to get it out of auto mode and my quad went crazy and crashed into my house. Second fun one was when the mission started but didn't finish, so I had to trudge across 60 acres of mud to retrieve my quad. Lastly I almost lost my quad on a mission that went awry, for some unknown reason it did 2 way points, then took off in the wrong direction, into the fog.  I tried to take back control, but I couldn't see it in the fog, then soon after I couldn't hear it either.  Then the sinking feeling came over me, $600 down the tubes! But fortunately I remembered to setup a safety switch that would return to home. I flipped  the switch and waited for what seemed like forever, then that wonderful sound of buzzing bees emerged out of the fog and my quad flew itself back home.  Phew!!  Learn these tips and tricks by watching this video, it could save you some money.
