Description

The new Auri DLG from LD Models is a great improvement over their previous designs, in both quality of construction and contest success. See this RCGroups post from the designer:

Last two years I flew the Stark Pro and found that it was rather hard to fly in dead air. Me myself prefer forward CG and speed flying. So, when thermals are very unstable or when you only have "good" and "bad" air Stark Pro never showed a sign it can climb in something.

My decision was to change the central wing airfoil section to make the model more sensitive to weak thermals. At the same time I wanted to keep penetration and speed of the plane near the same. Also I really like wing's planform of the Stark Pro and didn't want to change it. So, after hours with XFLR and Solid Works new airfoils were ready and we started our work on moulds.

It took 1.5 months to mill wing and tails moulds, sand and polish them. First prototype was ready 1 day before the first contest this season.

I was really surprised when I won that contest with ease. And it was only beginning of my amazing flying season with Auri. Now, when my flying season is over I can say that it is really big success of LD Models team.


The Auri is ideal for customers looking for great flying performance and model toughness at reasonable cost. The fuselage is a one piece design with a generous front to facilitate a four-servos-in-the-pod RC installation, eliminating the need for noseweight. The tailplane (horizontal stabiliser) and fin (vertical stab) are very light and have a good finish. The rudder and elevator are ready hinged, and wing gap tape has been fitted to minimise drag and improve the control response.

The wing is beautifully molded from spread carbon with a Rohacell core to maximise strength and dimensional stability, ensuring the surface finish stays smooth. The design incorporates nicely designed ailerons to give excellent control at all speeds. The hinge gap is sealed with hinge tape, eliminating a common drag source and ensuring high launches.

The supplied accessories include servo mount, tail pylon, aileron pushrods, rudder and elevator pull cables, torque springs, all control horns and a nice asymmetrical throwing blade.

Awesome Auri

Beautiful to look at and a joy to fly. The Auri is my third DLG having had Longshots previously. The finish is good. The glider goes together easily but I did have to spend time studying build threads and photos to work out certain measurements. Mine came in at 226g and is the first plane I have built that balanced straight off without the need for adding weight, somewhere! Flying it is simply a joy. Launches are easy. It can float, turns nice circles, or can whiz through the sky. Easy to fly - the challenge being to fly it well. I canít get enough of it to be honest. Worth every penny.

Auri

Great dlg brought this to replace alula fairy straight forward build 4xkts servos on 2s and the option for 1s only had the maiden flight so far due to weather
As for the flight fantastic great thermaling and speed a good all rounder 10/10

Auri dlg

The Auri flies extremely well. With four KST X08 HV servos mounted on the supplied servo mount and a 300mAh 7.4V battery up front the model weighs 230 grams and balances at 63mm from wing leading edge without any added weight. Fitting the aileron control rods was not straightforward. Cyano did not glue the rods effectively to the carbon fuselage and had to be backed up with epoxy adding a few grams of weight. The canopy is about 2mm too narrow and 2mm too short to be a good fit. Otherwise a great quality kit and once the Auri gets airborne the small niggles are soon forgotten.

Auri DLG

I bought the Auri in early June and it arrived in California approximately 7 days later in large cardboard box. The build quality is excellent and the surface finish is extremely smooth. Assembly was straightforward with the help of online videos and threads. I completed the build start to finish in one 8 hour block of time. The plane thermals really well on calm days and is a capable ridge soaring plane on windy days. Im using a spektrum receiver with an internal antenna and I haven't had any issues with signal loss through the pod.

Auri DLG

Fantastic. A straightforward build due to high quality of fit and finish. But, its in the air where the Auri really excels, agile and responsive to the weakest of thermals or wickedly fast with just a small amount of reflex - you can even pop in a bit of ballast and go off to the slope - this little gem really is that good. KST X08 servos are well suited and fit to perfection. I have over 250 fun filled flights completed and can honestly recommend the Auri to anyone in the market for a new F3K airframe. Well done LD Models. Top marks.


 Review by:

After having owned a few of the top end models like Snipes/NXT/NRJ/Vortex 2+3 I settled on the Auri. I am very impressed with these planes, whilst I have yet to fly mine, I cannot fault it's build quality for the price, it's very very close to that of the top end designs. The wing in the standard textreme layup is both stiff and really glossy. The Carbon tails on mine are on par with the above brands, very well made. I love the fuse design, the pod is around the same size as the Vortex 3 so plenty of room for your rc gear and the 4 in pod layout is super easy to set up, I will never go back to top drive designs. The boom is a interesting square section and extremely stiff and the socket for the rudder is the best fit I've seen on any of the designs. Whilst the wing may not be the current hype of small chord, I am expecting it to be far easier to fly and easier to set up which for me will equal enjoying flying it far more than I did with my last model. Dimitry of LD models is super quick to respond to any questions you may have also, unlike some other brands which never reply. I would definitely recommend the Auri if you're looking for a new dlg and usual first class service from Neil at Hyperflight.

AURI

As with the Malibu Pro the AURI arrived at my doorstep in Australia six days after placing my order with Hyperflight. The AURI was well packaged. All components were accounted for and of high quality.
I am about to complete the build which includes fitting 4x KST X08 V5.0 servos, micro receiver and a 2S 300ma Lipo. The only change I have made is fitting Kevlar string elevator and rudder rods. The build is relatively easy and well supported by pictures posted on RCGroup AURI.
Concluding, again the whole process of ordering and dealing with Hyperflight has been a positive experience and I will be dealing with this organisation again.

Good DLG

Excellent job from hyperflight on packaging. Arrived in just 6 days. I'm getting really long flight times also on fine thermals. When having the flaps set to thermal mode, you'll get much longer flight times. I setup the CG about 5mm more to the front. On throwing I'm getting a few meters less than with the Snipe 2. All in all, I'm happy.

Auri DLG

I bought one of these Auri DLG from Neil at the beginning of the month.
It arrived very quickly ,perfectly packed so no damage to model on arrival !
The quality build of this model is SO GOOD ,but some of the assembly was not as I am used to, but plenty of help is available. I completed the model with 4 KST X08 servos, G-RX6 RX, and 2cell 350mah Lipo at 230g. It is an absolute pleasure to fly with CG at 64mm and recommended settings. I have flown it now for around 2hours and am VERY pleased with it !!!!! 5STAR Product at great price.

Great build quality really good dlg very happy. Well packaged and fast delivery as allways

As always, concise and perfect packaging.
What surprised me was that it reached me in Japan just 5 days after ordering. Great!

Auri

The Auri has a very wide speed range...able to float in light air yet still able to cover a
large area looking for thermals in Cruise mode. Aesthetically it is a very attractive aircraft with a slightly bulbous nose with lots of room for servos and a high aspect wing that is able to turn in tight thermals with ease. With 4 KST XO8 servos, 300mah 2S battery and a Lemon Telemetry RX mine weighs in at 236 g with 2 g of nose weight. Great cost to fun ratio!

Auri F3k

Excellent service, packaging first class had the Auri flying in 2 days, what a wonderful aircraft, the right choice


 Review by:

As a newcomer to the DLG scene this was my first full size model ( I also have an Elf Mini ) and I was not disappointed. The quality of the kit is excellent and although things like springs and pull cables were totally alien to me with care and help from the RC Groups Auri thread it didnít take too long to put everything together. I have only had two flight sessions with the model so far but the Auri achieves great altitude with a reasonable launch, floats well and picks up thermals easily. I did Have a problem with the receiver battery that I purchased at the same time but Neil sorted this out immediately with a replacement that arrived the following day - great customer service as usual.

Auri

Fantastic glider for the money. Flies well and shows thermal activity very well I think due to the wing design. Nicely made but not quite the finish quality of a Vladimir Snipe but still well worth the money and a great performer.


 Review by:

It,s easy to make and auri dlg is also obedient to a flight and thinks the steering is also easy also I bear comparison with the expensive fuselage which often also Gose up lunch. The packing of mr hyperflight was also perfect and l admired.

Worth more than price

AURI is the latest competition DLG design from Dmitriy Lomovtsev features thin wing profile.
Easy to built, easy to fly and floats surprisingly well. Penetrate well in windy condition.
AURI will fit many flyers, from intermediate to top level competitors.
Of course, my kits were delivered without any damage thanks to Hyperflight's excellent packing as always !
