West Meon Valley

The best -laid plans…

4K brings us some additional detail under the bright afternoon sun…

It was a perfect Saturday afternoon – minimal wind, lots of bright sun, and I was out on a flying mission, having been told by a friend about how excellent Old Winchester Hill was. It sounded like the perfect place to fly ! Imagine my disappointment when I got there, having driven for about an hour, only to discover their ‘No Drones’ signs. Very disappointing that once again the most picturesque areas of the countryside are off-limits to the people best equipped to promote them. I didn’t contribute to their parking fund, and left to see what the landscape was like a mile down the road from their nature reserve. Not as good as it turns out ! Found an empty field with a public footpath in it, but there was nothing interesting on the ground, so we had to get up nice and high to see the aerial goodness. Unfortunately OWH was largely obscured by its perimeter hills, but you can’t win ’em all…

Difficult to feel like you’re winning when your landing pad is the most interesting thing on the ground !

Testing Times

Today was the first time I am trying 4K recording which I am transcoding down to 1080p in Handbrake. This is giving me much more detail in things like grass and trees and holds to Youtube compression much better than filming in 1080 natively. Some camera problems evident (weird dimming flashes every second while in the air but not on the ground) and this will start a 3 month long battle to find out what that is, but for now the test has worked, and I will be filming in 4K from now on if I can eradicate the aforementioned video problems, which only seem to occur at 4K and in certain video modes.

Flight Control

The H performed admirably again for this session – there might not have been much wind on the ground, but there was  alot more up high, but she remained dutifully nailed to the sky wherever she was placed, and flight control was positive and reliable. No video drops up to about 500 meters out. What was less-then-perfect were the barometer readings – for some reason when mostors start there is a 50% chance that my reported altitude will start dropping even while the craft is stationary, and continuing when I launch upwards. I am resolved to watch that over future flights as it could impact the staged decent trajectory of the craft if the altitude is more than 10 ft wrong. People have reported the TH refusing to descend, which I think may be linked to this barometer inaccuracy.

Endless greens…

 

See you next time…
