My quadcopter attacked me

I was disconnecting the battery when the motors went full throttle and sliced me up good.

Paragliding XC from Tapalpa, MX

March 4th, 2014

In February I went to Tapalpa,MX with Granger from Parasoft Paragliding. This was my second trip to Tapalpa. Armed with my pod harness and my newly aquired Ozone M4 I wanted to put some hours on this wing before the XC season started in California. Below are photos of tracklogs from two XC flights from this trip. Leonardo Link

Out the Bull Field XCXC Flight #1. Launch from Tapalpa, follow the concave ridge out to the cross (Cruz de Techaluta) and glide out to the main road by the flats. I had the lofty goal of possibly flying all the way to San Marcos but I decided I’d made my goal for the day and landed within easy retrieve distance.

Dem BullsI had quite some time to pick an LZ but alas I picked the one field filled with about 20 juvenile bulls. Luckily they were confused by the balled up paraglider and gave me just enough time to walk over to the gate and toss my gear over the barbed wire. A taxi ended up stopping for my by the road and I got right to the main road up to Tapalpa.  Total of 15.7 miles XC distance.





My second XC flight was an extension of the first.  The first leg was to the cross (Cruz de Techaluta) then back to Tapalpa LZ, then to Sayula LZ.  At the cross I had the choice of going straight line to Tapalpa LZ or following the ridge back to launch to tank up and then hit the second turnpoint. I chose the latter.  Total XC distance : 24.3 miles.  (Leonardo Link)

Screen Shot 2014-03-04 at 4 Tue 2.52.28 PM I launched rather early and had to scratch around for quite a while before getting enough altitude to attempt crossing the “Power Lines of No Return”.  The blue colored track in the image on the right shows the flight just after launch.

Below you can see the outbound trip as the bluish track.  There was a slight headwind but thermals were abundant and mostly where I expected to find them.

The first turnpoint was the cross of Techaluta.

Shortly after turning around to follow the ridge back to Launch I saw another pilot on a Niviuk wing coming the other way.  We circled in a thermal for a few turns and then waved goodbye as he was continuing on.  The wind had increased slightly giving me a really nice pace on the way back to Launch.  In the image below you can see the increased ground speed of the downwind glides as a deeper red and yellow colored track compared to the outbound track which is mostly green.

Screen Shot 2014-03-04 at 4 Tue 3.04.49 PMJust before crossing back over the “Power Lines of no Return” I got a nice thermal making it easier to get back to Launch.  You can see where the power lines are by the large swath of cleared land at the bottom of the picture on the right.

















Once I got back to launch I tanked up and headed out the second turnpoint out in the flats.  I tagged the cylinder and return to the hill to find a really nice thermal.Screen Shot 2014-03-04 at 4 Tue 3.05.30 PM

The last thermal gave me the glide to reach Sayula and I even had to spiral down in sink because it was getting very buoyant out there.

Using CHIRP to program the Yaesu VX-8G

September 4th, 2013


Before modding my radio I had to backup all the channels and banks in memory. I first dumped the memory to a chirp dump file. Then I modded the radio which erased all the channels. Then I tried to upload the channels back to the radio but I kept getting an error that the radio did not ack block 1. CHIRP is weird because it can work with so many different radios. In order to get old channels uploaded to the radio I had to download the blank memory from the newly modded radio. Copy/paste the channel data from the old dump file to the new dump file and then upload the newly pasted-to file. It worked !

I hope this might help somebody else having the same problem.

Also, when downloading the memory bank to the computer (cloning out) you have push the button on the radio after clicking the download button on the computer. When uploading, you have push the button on the radio before clicking the upload button on the computer.

To get into clone mode hold the func button while powering on. To receive data push the mode button, to send push the band button.
