The Purito is probably the best 2m RES build-it-yourself model currently available. We now have the latest 2.0 version with many detail improvements. A direct descendant of the Pures and the Slight the Schweiger family concern have optimised the design as far as possible with current (2020) CNC technology. The main design change is to a lower aspect ratio wing to increase the Reynolds Number and give better overall performance and particularly nice handling. Despite the larger wing the weight has been kept the same, resulting in a lower wing loading and excellent performance in weak conditions.

The Purito V2.0 flies like a homesick angel and despite its light weight the model has a surprisingly good speed range. As Greg wrote in the RCGroups thread "The big wing bestows a good launch, even when the wind is light; the airplane itself has little drag, so displays very good legs; handling is easy, allowing the pilot to concentrate on thermalling; and finally, the spoilers really make spot landings quite easy."

The amazing wing is the major improvement of this design. The main spar is a substantial carbon tube which gives the structure excellent rigidity. A multitude of ribs are threaded over this tube to give the airfoil shape. This is even better maintained over the critical front portion by utilising two sub-ribs between each full rib, almost eliminating covering sag, and reducing drag appreciably. Becuse the tubular spar is inset below the covering surface there isn't a discontinuity at the spar line which is great feature - this usually trips the boundary layer and causes extra drag.

The kit is beatifully made up with excellently CNC cut balsa and ply parts. The wing is built over/in a 3D jig which ensures all the ribs are perfectly placed and aligned. This can be seen in the clear photos in the Purito German Build Manual. In addition to the manual, full size plans are povided for the tail surfaces. English speakers should refer to the RCGroups Purito thread for detailed build info and Google translate the German text if necessary. Also use Google Translate on this very useful Purito thread.

Nice Kit, the instructions bleak at best

The kit is nice, that said, you have to really scour the internet for instructions.
Oh they give you a link to You Tube, and RC Groups, then you have to decipher the mess and begin building.
Again it is a nice kit, and there are techincs you neew to know in order to build it correctly.
Order response for the kit and the required servos, was top notch and fast. I ended up having to make 3 orders to get all the stuff i wanted to complete the kit, except for the covering, apparently there is now a film shortage.
So now the kit sits in a box partially assembled.

Purito 2m

This was the third Purito I have built, the first two being part of a Build Thread on RCGroups. Just like the previous pair, this kit was simply superb in packing and fit-and-finish. I was startled to find there are no instructions, nor even a complete drawing, but thanks to prior experience, it went together with no issues. I was pleased to find that my own Build Thread on RCGroups enabled me to fill in any missing spaces in how to build the airplane. I set the CG to the kit-specified location, and I have flown this airplane successive times with no subsequent adjustments.

Backed up with Neil's usual excellent responsiveness and service, this has been a fun time for me.

My recommendation: if you are an experienced builder, you will enjoy this airplane!

Lacking quality instructions

This is my second RES build the kit is very nice everything fitted well it's a shame there are no instructions but bouncing between the dodgy English translation (for the e version) the rc groups build thread and German pdf it came together but some parts needed research as to where and how they went. It went together quickly my AUW is 430g I'm looking forward to it's maiden.

Trying to assemble the jig saw kit without readable directions is a problem. Now I built my first free flight in 1953 and have built many planes over the years. Trying to figure out how it goes together and where the parts go is a problem. Like how to assemble the parts for the tow hook. The wing set up was petty good. Iíve got it assembled I found the English for the electric set up but none for the other one. The RC groups helps but does not give what I need. The glider will be what I want when I finish it.

Iíd say the parts fit better than anything Iíve found in a kit in the past.

Still need to locate the tow hook and how itís meant to be assemble.

Purito 2m RES

To complete my earlier building review, I can now add that the slope flying experience with the Purito has proven to be excellent. Even on unpromising days it manages to float gently on the 'thinnest' of air. Trim can be quite sensitive, but once you find the sweet spot it responds wonderfully and indicates gentle lift very well indeed. Excellent light weather model.

Purito 2m RES kit

Recently I built the PURES 2m kit and was delighted, both with how the kit went together and with the model's performance, both on the flat and up the hill on fairly gentle days. I'm now in the finishing stages of the Purito (glider) kit and it has been an even better building experience, if that were possible! An absolute joy to assmble a kit such as this with parts that are cut with such awesome precision and go together like a 1st class well-fitting jigsaw. At the same time I also bought the electric fuselage, so that I could swap between glider and electric versions. I'll report shortly on how the glider version flies - and how the electric version performs when that's completed.

As always, the service from Neil and his team at Hyperflight was brilliant; excellent packaging and very fast delivery.

Beautiful Kit. First rate wood and design. Thinking about getting another. Neil has great service. Highly recommended.
