It is sunny, we have a task!
Didn't feel the need for breakfast this morning following last night's curry! The briefing at 8am set us on our way to Broughton Heights - a site I'd failed to get away from last year. Expectation was for light westerly winds going around to the N and NE later in the day. The ground was expected to be very soft, so we'd have a walk up the hill, but this didn't stop some from attempting to drive 4x4s up. Calvo (meet director) got stuck and required towing out courtesy of the farmer and his tractor, much to the amusement of all on-lookers.
Whilst some tested the air, and the organisers planned the task, I set up the new wing and ground handled for a bit to get a feel of it. The Cobra comes up nice and easy and sits overhead, with no apparent tendency to overshoot. The lines are very clean. My initial impression, having come from a Sport, is that it looks small and thin! (The Cobra has an aspect ration of nearly 6:1 as opposed to the Sport's 5.2)
The task was called. A straight race to Hawick, 46km ESE. The wind was already going around to the north, clouds were developing and likely to be an issue. The window opened but pilots were not in a rush to get off as winds were very light now and we were relying on thermic cycles. Gradually though gaggles worked the cycles and each time a few got away. My first flight came to nothing as I didn't quite catch the thermal and decided to side land rather than risk ending up down low. My second attempt was good and I climbed up several hundred foot above launch before loosing the thermal and sank back down with everyone else. There were still a good number of us who hadn't got away and were hunting around in the bowl going up and down. Also a number still on the deck finding it hard to take-off now as the wind continued to veer round to the N and E. I thought I'd blown it and I'd be stuck here, but at least I'd be giving the wing a good work-out. However I got lucky with a thermal that I felt happy to work on the lee side and with a couple of others I was up and away!
So how does the Cobra fly? Well, I'm no expert reviewer, and these are just my impressions from a single flight: The first thing I noted is that it is indeed quick quick and nimble, but quite refined. It's agile and responds well to weight shift followed by a little bit of brake to get into a good turn. Now I haven't flown many wings, however agile wings that I have have felt a bit light and delicate. The Cobra though feels pretty solid - agility without fragility! I hope this proves to be the case, it seems to me to be quite impressive for a LTF-2 wing. During the flight I found it climbed really well, giving good feedback without being "over-talkative". The pitch neutrality is going to take a bit of getting used to as there is little tendency to pitch into or away from thermals as you go in. I found "scrappy air" a bit harder to read than I've found on some other wings, but that said I had more time to float around to sketch it out as the Cobra is definitely "floaty". Indeed I found that I was out-climbing other wings more often than not when thermalling (although I have a pretty small sample for this statement!).
During the flight the cloud cover continued to build and the skies got fairly threatening. There was quite a downpour going on 20kms or so out to the east. I had just one moment where the wing didn't do anything other than fly smoothly. About mid-flight I suffered a full frontal (I think) and the wing's 6:1 aspect ratio became 1:1! Expecting things to get dramatic, I was somewhat surprised as the wing barely pitched, calmly re-inflated and resumed its service. It was a remarkably mellow experience, as if the wing was a trusty unflappable butler, calmly apologising having been knocked by an unruly guest before continuing a dignified service.
I flew on, staying clear of cloud-base and in sight of blue holes, and tried out the speed system. This has a more complex riser modification set-up than I'm use to (apparently to modify the shape of the wing beyond simply its angle of attack), but application of speed bar is really smooth and easy. I soon found myself making use of the bar throughout the rest of the flight. A couple of thermals later (and a bit of sleet!) and I could see goal in the distance. I just needed one more good climb. I could see wings well to the east and well to the west of me (I figured they must be free flying, but it later turned out that competitors in the task had taken a wide range of direction options for the task), and one landing next to the river Ettrick below me. The terrain beyond was a good stretch of moorland so plenty of landing options, but with no good road access. So if I had to land it'd be a long walk out, but I was in a gentle climb, so I decided to continue. As it was I didn't have to make a decision to land due to the incoming weather as a I hit the sea breeze and got sunk out to land right in the middle of the expanse, about 9k short of the goal cylinder. Landing had been nice and easy, and having packed away after an enjoyable flight, my luck continued as some anglers, having finished their fishing for the day, strolled past and offered me a lift down to the road.
We picked up Chris who had flown about 0.5k further than I had as we drove down to Ashkirk where he and I exchanged stories of the day's flying over a nice cold pint. Carolyn came to pick us up having had, sadly, an unsuccessful flying day. Apparently I'd been in pretty much the last group to get away from the mountain. The wind went around to come over the back. Carolyn had laid out, but then a gust came down over the back, rolling the wing down and then dragged it, and her, back up the hill. - "I got rotored on the ground!", - Carolyn
So, I didn't make goal, but it was a good flight, and I didn't get hailed upon in the landing field or have to spiral down to escape the weather! In the end I came a respectable (I think) 19th. Not bad for the first flight on a new wing. Overall I think I'd sum up my impression of the Cobra as having more the sense of a refined GT car than a feisty supercar. Flight details are
