D130 Continued....

DS certainly promotes a reaction! Those that have tried it have experienced the sheer additive nature of incredible speed and inherent danger involved which leaves others wondering why you ever need to go so fast.

What is also certain is that expense is high, attrition is high and commitment too. The trend for faster planes is to make them bigger. Of course there are exceptions and talent and opportunity with just the right conditions play their part too. However, bigger DS planes are actually easier to fly because you fly a larger circuit and so less load on pilot reaction times for any given speed. They also, quite understandably, become scarier too as the sheer size and weight get's into territories you just would not think a glider should be! After seeing so many 'hits' over Simon Cocker's 'maidening' of his D130, I asked him to tell us mere mortals what his thought were, so far, with this astonishing but admittedly, intimidating machine...

"With a wing loading of 49 oz/sqft the D130 could be construed as a heavy lead sled. picking up 30 pounds of hewn carbon in the workshop and having that mass comfortably sitting in one hand felt like picking up a steel dumb bell in the gym; all that money invested in the airframe appeared crazy; then there was also the 5 Hitec HT-7990 44Kg torque servos at £100 each..etc. I could at this point understand why there was a great deal of perceived intimidation from fellow flying friends. After all, this machine is designed to break 500mph in the DS zone but by no means break itself in the process.
After five front side flights so far in wind speeds of 25/40 mph on two different days I can tell you that the D-130 is user friendly to fly and land.The model carries energy in a rather unique way and sure covers a whole lot of sky in all axis. The Long Mynd has been used so far but the Great Orme is next for front side sessions.
I have a sport/front side and DS setting but look forward to switching into the latter mode when winds onto Rushup Edge will allow.
The D130 is perfect for this re known DS site being of a size where really large circuits can be carved and still have a very safe visual lock on the beast.
I am not rushing out there, hell bent on busting any speed records,I am addicted to the DS adrenalin rush however. After three years of DSing various types of models including a 5m span all carbon Pilatus B-4 I was ready to go for another quite big "Propppaa" one, & as I have always proported "Bigger is better"...this notion has proved to be very much the case.
Safety is a most prevalent and ever present issue with this style of flying and I noticed the BARCS chatter which has rightly raised this point once more. We will Police this far more strictly and keep everyone out of harms way. I am very mindful of the potential danger and with our DS friends ensure appropriate steps are in place during all DS activity.
Joe Manor by the way makes a fantastically strong model which assembles in very short order,nice job Joe,thankyou."

Dynamic D130

The first Dynamic D130 (yes 130''  and its a light one at just 30lb, unballasted !!!) has been maidened on UK shores. It's a massive DS machine much bigger than it's span suggests and redefines how solidly a plane can be built. Owner, Simon Cocker say's its a big pussy cat but then he's used to big 1/3rd scalies and the like, but I think I did detect more than a hint of sarcasm in his voice! No doubt he is working up to getting the courage to wind her up on the 'backside' for some proper Dynamic Soaring,  in the interim I think his launcher needs to get himself to the gym and start bulking up!!! Surely an attempt on the UK DS record will be made and we wish Simon the very best of luck.

Simon adding some scale to this colossus of a DS machine!

For the less committed we have stocks of the D80's and D60's ( and the odd D40). The D60 in particular is not just for DS'ing and makes an incredible front side, heavy wind model even with 7 ounces of tip ballast in each wing- Just astonishing speed! We can only imagine what the D130 will be like but I guess we'll all be hearing soon enough!

Tiny pushrods- New Product

We've been getting a lot of call for our hardware especially the M2 303 grade stainless steel pushrods but sometimes you just need a tiny pushrod and even 2 clevises butted up against each other are too long!
Teeny pushrods!

A threaded studding is required and strong ones are hard to find. We had these made at 12mm L, which incidentally will take all the threads of stock MPX M2 clevises butted end to end.
RDH adapter to clevis
Clevis to clevis

Like all our pushrods this is made from 303 grade stainless steel and fit all M2 hardware saving you the hassle of cutting up threaded pushrods, M2 bolts or threading your own (yep, been there too!). Handy bag of 4 for £3.
In use on Schwing tail servo install with ball link, RDH adapter and bearing kit, so this one had the works!

Aresti takes first place in TOSS slope aerobatics contest!

Yes it surprised us too since the production Aresti is still in mould stage! Details can be found here in Steve Lange’s wonderful website dedicated to slope aerobatics

Video of Aresti flying

Hans Van Kamp of South Africa scratch built the Aresti from James Hammond’s drawings at 2.65m span and with Louis Genade at the sticks won the 5th Annual Two Oceans Slope Soarers aerobatic contest. Well done guys, you’ve done us proud! This is really encouraging for the new Aresti design with this little international collaboration.

I better get back to the epoxy fumes and get our Aresti prototypes made!
