That is a awesome site nice flyin fella's. How often do you guys fly there. That's a 500 mph site for sure. When's the best time to come over to fly at that spot.

It's good for frequent DS cruising all year round, but the stronger flyable winds are in Autumn/Winter (October to March).
I agree it has the potential for very fast speeds, but we very rarely have strongish S-SSW'ly winds unaccompanied by heavy rain, so anything OK to fly in over 30 mph is rare indeed.

Though we do have slightly better luck sometimes with other wind directions & have, also adjacent to Mam Tor ('MT', the highest point in the Peak District), two other good DS sites.

1)'RE'/Rushup Edge/Rushup: S-SSW; also DSes in N-NNE (shallower backside)
2)'MS' (curved ridge on shoulder of MT): NW-N; also DSes in SSE-SE
3) 'HH'/ Mt. Famine: WSW-W (WxS ideal).

And there's excellent frontside flying at MT in any wind direction.

Plus the S.Wales' DS sites are readily accessible (i.e. in Oz terms - only a few hours' drive!), e.g. Pen-Y-Fan, Skirrid & Black Hill.

Should you intend to come over, let us know & we'll look after you.

New 'Burner ready to go

About a year ago Kev very generously offered to lend me the Windburner Mk 2 wing moulds. This was just after he'd got the Mk 3 moulds CNC cut. I couldn't say no! For those that don't know the Mk 2 moulds were moulded off a hand-made plug that Kev shaped himself.

I made two wings from these moulds, but because of work and the Deepend I've only just got around to finishing the first one.

I wanted to experiment a little with the wing layups and see how quickly and easily a wing could be made. The layup in this first one is two layers of 200g carbon layed on the bias with no sandwich. The spars are three layers of 400g x 25mm uni-carbon in the middle tapering to two layers at the tips. Lots of uni-fibreglass was placed along the LE to help with weed-whacking. The main spar web is made from a carbon sock around foam, and the drag spars and elevon spars are made from 200g carbon wrapped around foam. Small strips of 400g uni carbon were placed chord-wise to act like ribs, stiffening the skin between the spars.

The wing turned out really well. It's extremely stiff, especially in torsion, feels like a mini Kinetic and weighs a relatively light 600g before servos. The no-sandwich concept worked well, the skins feel stiff and well supported thanks to the heavy layup and the fact there are no large unsupported areas of skin. The only issue was I had to clean up some over-spray and used a buffing machine to get the gloss back into the wing. The heat from the buffer shrank the skins back so you can see the uni carbon "ribs" sticking up slightly. For that reason I'd probably use a sandwich next time, although it did make for a very quick build without the sandwich.

I also built a second much heavier wing with a similar layup but using a sandwich. It has about one inch of solid epoxy/chopped glass along the LE, as well as lots of scrap carbon put into the D box for good measure, and some steel embedded in the tips... It came out at roughly twice the weight! That one still needs to have servos installed but is otherwise close to complete.

I bought a couple of fuses off Kev and they are bullet proof! The layup in the front of them is as thick as 5mm in places. If something breaks on this 'Burner it won't be the fuse!

Flying weight of this first one is 1.4KG. Should be a good weight for an average Cactus day.

I tried KST DS125MG servos in this one and I gotta say they're pretty good! The two I have do have a little slop, one worse than the other but it is less than many much more expensive servos I have bought. They centre well and seem quite precise and smooth in their movement. I can tell a difference between them and MKS 6125 in terms of gear tightness and precision, but it is not huge, and they cost less than 1/3 of what the MKS cost. At this much lower price I would expect a higher failure rate though, so personally I wouldn't put them in something heavy or expensive. I'm hoping they stand up to the abuse dished out by a heavy plank, we shall see...

Sean.

Nice! Scheme looks mint too

I would love to lay-up my own burner, have just the lay-up in mind for super fast Tekapo special. But I seriously think you need a bigger airframe to go much over 300, it is just so small and quick. I had some laps that were well over 300 but was so hard to keep track of

I got a text from Bruce. "The windburner was a handful. The first flight i went 314. then when we were loading up i measured another 64 gust so i decided to fly it again. I didn't hear any speeds but i thought i was going pretty good. Then Alan yeld out 331. Pulled right out and landed."
