Steve Blinky gets a snap of Dave and I doing that tandem thing.

While wind turbines allow us to harness the power of the wind to create a renewable source of energy, their spinning blades can also serve as a potential danger to wildlife. But a group of researchers in the UK may have found a solution to keep birds and bats away from the blades: by painting them purple.

According to the report, the reason that so many birds and bats flock to the turbines is that they offer up a feast of bugs to feed on. But by painting the turbines a different color, as opposed to the standard white or light grey, it may deter insects from landing on them, which in turn would keep birds and bats safe from the blades.

"Our major conclusion from this work is that turbine paint colour could be having a significant impact on the attraction of insect species to the structure, both during the day and at night," PhD student Chloe Long told the BBC. By testing various colors, the team determined that purple was the least attractive to insects and that white and grey where two of the most attractive colors.

"If the solution were as simple as painting turbine structures in a different colour this could provide a cost-effective mitigation strategy," explained Long. However, there may be other factors that make the turbines attractive to insects, such as the heat they give off.

Well, yes, it certainly does make him less attractive… But to Eagles?

How am I to follow such an insightful monologue? Let’s just bow our heads and acknowledge that winter can hit us all pretty hard.

Once we’re all resigned to a sledie at Stanwell, we decide to make things interesting by throwing in some water skimming action near the beach.

I went first but come in too high almost ending up in the ocean after rounding some fishing rods sticking up from the beach.

Dave though, picks it perfectly! As you’ll see from the video, there is a pretty small envelope in which to pull this off. Some of the most confident and well executed approach skills I have witnessed…

Needless to say, after borrowing Michael’s camera for this little effort we have ordered a few for our future shenanigans.

Flytec make great instruments. Apparently, they make pretty amusing ads as well. Bruce Wynne spotted a few around the place and sent them through.

Want to win a neat little RC Chopper courtesy of thebombout.com??? Read on…

It seems the Google Australia crew have gone pretty nuts with their Google car.

A huge chunk of Australia’s roads have now been photographed and incorporated into the street view database. This coverage not only includes most urban areas but also significant coverage of rural and in some cases downright obscure isolated places – perfect as that’s exactly where we like to set goals during comps and free flying. No more surprise power lines on final glide now.

So how I win the chopper?

Here’s the challenge:-

Your task is to have a bit of a look around and see how many hang gliders you are able to find photographed in Australia in street view. Gliders can be flying, setup or still in the bag though it is my final decision as to whether it’s a glider you’ve found or something else – canoes and carpet salesmen don’t count.

The person who is able to identify the most hang gliders by the 30th of September 2008 will get the chopper.

Send your entries, including locations, through to huntingforhanggliders@thebombout.com before the end of September.

Good luck!

TIP: You’ve all seen the little green twitter box on the left hand side of the page. Keep an eye on it for clues as to where some of the gliders are located. Better still, follow me on twitter by clicking here and signing up. Once you are following me on twitter then you can set it up to send the updates through to your phone for free.

Just been going back through some old emails and I came across this… Damn it has been a fun ride getting a foot into this sport.

Saturday

Karl, Dan and I headed out the lake intending to get some ridge soaring in. Winds were a bit light for that sort of action – none of the 20 or so visiting punters were getting up so I didn’t think that we had much of a chance. I was keen to try out the Blitz that Scotty had so graciously given me but decided that I would have enough problems trying to stay up in the Sonic this would not be a great time to complicate the issue by stepping off in new glider.

As expected that was a short sleddy. Time to try something different.

We headed to the north launch. At least our sled ride would be a little longer from there. After setting up, the wind had still not picked up much. The butterflies had set in to my stomach. This was the first time I had flown in anything other than my Sonic (other than one of Tove’s funs). How would it handle? I had no idea what to expect. My plan was just to run like hell to get the thing off the ground and flare like hell to make the thing stop. Anything I learnt in between would just be a plus. Dan launched first but had a bit of bad luck and ended up heading straight down to the bombout.

My turn. Hang checked and ready to go. The lack of wind up the face was doing nothing for the nerves. I waited for a while hoping the wind would pick up. No luck. Great, a nil winder in an unfamiliar glider.

Off I ran. It took a little longer to get off the ground than what I’m used to but it was a lot less stressful than I had expected. Landing gear up. Immediately you notice the glide ratio. I was moving much quicker than in the sonic and was sinking much slower. For an old glider it felt great.

Ok let’s try turning this thing. I had been told many times that I would have to get used to a new method of weight shifting due to the slow response time of these more advanced gliders. Weight shift, return to the centre and wait for it to respond I had been told, so that’s what I did. It was a little strange as I made my first turn but nothing unexpected.

Then beep. Cool. Beep beep. I knew that sound. Playing on the side of caution I started with a few figure eights careful not to get too close to terrain. A few passes and I was above the ridge. Time to hook in. Thremaling felt pretty much the same as what I was used to but it took a bit more effort to stay in the core. By this time the punters were streaming off the hill. Some going up, some going down.

A punter with a white wing and a red leading edge soon found my thermal. We took that up to 1500’ above launch. I took this opportunity to try a few things in the new glider. First I tried pushing out a bit more to increase climb rate. I do tend to push out a fair bit in the Sonic to milk a thermal for all that its worth – you hardly notice when it stalls anyway. I knew that this would be different in the Blitz but with this much height I didn’t really care. Edging the bar out while in the thermal was fine but as you venture to the edge of the thermal the wing in sink tends to fall out of the sky. It recovers itself ok but you lose a bit of height in the process.

Karl was off. He was in another thermal off to the left of launch. I wanted to join him so off I set. Let’s try out this vg thing. I pulled on the rope – bugger. It was stuck. I hadn’t checked it in my preflight as I didn’t think there would be much of a need for it in the sled ride I was expecting. Oh well, I was still moving a lot quicker than I was used to and maintaining more height in the process. We circled around for a bit then ventured off on various sorties but encountered nothing in any direction.

By this time I was fairly used to flying the Blitz. Time to think about landing. I picked out a big area in the bomb out paddock to allow for the extra distance I would travel in ground effect. Setting for the landing was like normal just a bit quicker. A nice quick final and down into ground effect. I have watched you good guys do this a hundred times and it felt exactly like I had expected. The Sonic gives you a touch of ground effect but nothing like this. The Blitz seems to give some fairly good feedback as to when it wanted to be flared. Once again I heeded the advice of those who have been there before – When you flare commit to it. With one big push up and out it stopped, a couple of steps and the ride was over. That seemed even easier than the Sonic but I think it was only beginner’s luck. I’m sure I’ve jinxed myself for next time.

This was a very enjoyable first flight in the Blitz I can’t wait to head out again.

I was really looking forward to Stanwell the next day… 3 times I have been to Stanwell. 3 times it has been too weak/too north/too south. Would tomorrow be any different?

Sunday

It was Michael’s plan to set off early. 5:30am was the call. What the!

To my surprise, Karl turned up on my door step with Michael. On with the gliders and off we set. After a brecky stop on the way up we arrived on the hill at 8:30am. It was ON! A nice call with the early start Michael. The wind was light though, so the Blitz would be staying in the bag.

Karl and I stuffed batons and launched at around 9am. There was a fair bit of south in it but still easy to stay up. There was no traffic in the air at that time of the day – just one para, Karl and I. Michael launched shortly after in his punter. Together we flew back South over the town and railway line. The scenery is beautiful from up here.

A train passes beneath, the fumes drift up and meet us together with a rush of rising air. A few quick circles get us above the ridge and the houses perched on top of the cliff. What a place to live.

Throughout this flight though there was one unsettling thought I was unable to shake from my mind… As an inland pilot mainly flying flatlands (or close to it) I like to have options. The whole time I’m flying I’m thinking – ‘If all else fails I can land there’. This is not the case around here in my floater. I have virtually no ridge soaring experience other than Lake George where the suggestion of looking for landing options is laughable. I am uncomfortable with this feeling but everyone else is getting away with it so I’ll draw some comfort from that.

Karl and I get itchy feet and attempt to push south onto the next ridge down. No luck. All we can find is rotor off the hill out in front and we are soon making our way back around to the chute. Karl lands first. I come in over the top of him take a few steps and drop the nose into the sand. Damn.

Michael, laughing at our feeble attempt to push south, top lands and drives down to pick us up.

Back to the top we head. By this time all the local pilots were up there along with the tandems and punters galore. This was more what I expected of Stanwell. That said no one was too keen to head off as the wind was still pretty light.

Nick and Matt had a couple of great flights around while most of the others headed to the bomb out to end their elongated sled rides.

Eventually we work up the courage to leap off. Though the wind was still light it was now straight up the face. North was the order of the afternoon we gained height on the cliffs off to the left and on to the clearings where the remote control gliders and zagis were zooming about. This was pretty cool. Another strange thing though is how blasé the locals are to the gliders swooping down beside them. At the lake everyone beeps there horn and waves to you if you’re low enough for them to see you. Sydney siders though, won’t cast an eye upward even after passing your shadow over their head. That said the crowds on bald hill are pretty cool.

So we continue North and I get my first view of Hell Hole. Interesting. I’m just going to boat around here for a while before I build up the courage to take this one on. Eventually Michael leads the way around the bowl without losing any height. He made that look easy so I follow. I didn’t lose any height but certainly didn’t gain any either as I make my way around.

As I get to the northern side of Hell Hole I encounter some wicked rotor from the outcrop in front of me. I lost a lot of height as I pulled in the bar attempting to get in front of the ridge. I rounded the corner and realised that I had a problem. I was low. The guys who knew what they were doing were high on the ridge 300’ above me. To say that landing options were sparse was an understatement. There was one beach within glide. A noticeable feature of this rather tranquil landing option was that it was totally void of anything that resembled a road. With this in mind I was keen to get back up but the vario was silent. I knew I had to get in close to the trees to get into strongest part of the lift. I tried to get as close as I could but I just wasn’t game to get as close as I needed to. Still dropping I had to try something else so I headed out to the headland hoping to get something, anything off the cliffs. Still nothing. Damn I have a lot to learn about this coastal stuff.

Time to plan my landing on the beach. It was a reasonably large LZ though I would be coming in crosswind. I spotted a family at the far end of the beach so I aim to land somewhere near them. Ever mindful of the walk ahead I find some comfort in the fact the there was a couple of 5 year old kids out with their mum celebrating mothers day – If they could manage to walk down onto the beach surely I could make the walk back out.

So I setup to land South to North (god knows why, there had been more South in it all day). I attempted to turn into the wind just a fraction while in ground effect but I still managed to drop the nose as the tail wind was still a bit too strong. Bugger. I walked my glider over beside the family I had spotted from the air.

I started by asking them “I have a problem don’t I”. During the conversation that followed enlighten that I had a 2.5km walk back to the top of the ridge. Not great news but it could have been worse. Karl, by this time, had landed back at Stanwell and was on the phone. I gave him rundown on my situation and instructed them to have a beer and some lunch and that I would give them a call when I reached the car park. After being on the other end of a couple of these sort of long retrieves I was keen to dig myself out of this one.

Now packed up, off I set. The path was bloody steep – this was going to take a while. An hour later I was about a kilometre and a half into my journey. I was hot and buggered. My camel back had been sucked dry while I was still back on the beach. I soldier on a bit further when a guy, taking his 74 year old mother on their annual mother’s day trip down the beach I now know as being Burning Palms offers to give me a hand. This guy was a legend. He grabbed the back of my glider and we storm up the hill. I gave the guys a call when we’re 500m from the car park.

We reach the top right as Michael and Karl pull in. Nice timing. After telling some of the local guys where I had landed they had expected the worst and were ready of a lengthy walk. The relief was clear on their faces.

The trip home gave me plenty of time to reflect on my mistakes and just how different this coastal flying was to what I am used to. I can’t wait to have another go.

Thanks Michael for chauffeuring us up and back. Also big thanks again to Scott Hannaford for the Blitz, I can’t wait to try it out again.
