Description

HyperFlight are very pleased to be able to supply the iconic Slite V2 model. This is probably the most highly regarded model designed for the F3-RES 2m balsa glider class, and we have been trying to source it for many years.

In 2011 Josef Gergetz of SETA Modelltechnik started to manufacture high quality sailplane kits for the newly emerging 2m build up glider competition class. By the end of 2017 the demand for Slite V2 was so high that Josef Gergetz could no longer keep up with the production. Delivery times were up 9 months and it was decided to switch the production to lasercut technology at a larger manufacturer. It has taken this long to complete this process, but now we are able to quickly supply this model to customers world-wide.

The Slite V2 uses a slightly modified version of the highly regarded AG24 - AG26 airfoil family by Mark Drela. To allow accurate construction of the originally very thin trailing edge the rear of the airfoil was slightly thickened. It gives high lift with comparatively little drag over a wide range of lift coefficients (Cl). Compared to the Pures V2 the Slite V2 has improved L/D, especially at higher speeds.

The wing of the Slite V2 is, like the Pures V2, is built as an open rib construction over very strong wound carbon fiber tube spars. To reduce sagging of the covering film between the ribs two extra sub ribs are used between each full rib. This ensures the wing profile conforms much better to Mark Drela's original airfoil than other built-up designs.

A balsa jig is supplied to ease positioning of the numerous ribs, ensuring the wing is built in an accurate and speedy manner. The laser cut structure is almost identical to the previous CNC version as there was nearly nothing to improve.

What is new? Besides the new lasercut production, the components are now numbered to ease building. Furthermore, there is an excellent multicolored construction plan and richly illustrated building instructions (in German only). Please see the Slite V2 and New Slite Available RC Groups threads for good English language build info.

Wing construction
The optimised design uses wound carbon fiber spar tubes, a tapered tail boom and pultruded carbon fibre tubes for the leading edge. The Slite V2 has a three piece wing and is built as an open tubular spar rib construction. The wing joiner is made of 4mm steel wire and is positioned directly in the spar tube. The flat inner wing (with the central airbrake) has an elliptical planform. The elliptical mid panels are joined to the center panel with a dihedral of 8° and are fixed with a specially milled plastic clip to make sure that they don't slip out during the flight. No need to tape anymore! The lightweight tip panel is joined to the mid panel with a dihedral of 12°.

Fuselage construction
The front of the fuselage is made from balsa with plywood reinforcements and plywood formers. Behind the wing, the wooden fuselage joins the CRP tail boom (wound, tapered carbon fiber spar tube) which is supplied slotted to take the fin. Two holes are already drilled for the horizontal stabilizer pylon and the slots for the bowden tubes are already milled out. The CRP tail boom is manufactured in the same way as the tubular carbon spars of the wings to similarly minimise weight and maximise stiffness. The fuselage is wide enough to fit a single 2600 mAh Li-Ion cell.

Tailplane construction
The Drela HT12 mod profiled tailplane is constructed with balsa ribs, CRP tubular spar and a balsa leading edge.

Electric Modification
The Slite fuselage is very narrow, being only 26 mm wide at the front. Most electric motors will be too large to fit but the Vladimir's Models Snipe 2e Powertrain could probably be made to work with only minor modifications.

The kit consists of carefully selected and numbered laser cut balsa and plywood parts. All small parts and good quality linkages are included in the kit. RC components, glues and covering material are not included.

The orignal V tail version, the current Slite V2 flies even better.



We received this very useful electrification suggestions email from a good customer. See the last (composite) photos above.

At the start of March 2020 I bought a SliteV2 from you and have already sent you a first inspection review. Build is now well on with flying surfaces finished and am working on the fuselage. I did say to you that I intended to electrify the model but only for sport purposes. You may be interested if others enquire in my how to do it notes.
I am surprised how simple it proves to be. Firstly I did not use the two small diameter motors I bought from you as I found a 23mm diameter inrunner lying in a box....no idea what make it is, but it does run nicely on two cells using an Overlander 20A ESC (this latter may be a bit of overkill but better safe than sorry.

Stage1. The nose needs its height and width increasing slightly. For scale my spinner in the photo is 30mm diameter.
First build the fuselage as normal from the boom mount forward to and including the main former (R11)at the leading edge of the wing.
DO NOT glue the fuselage internal ply edge strips (R3,R4)to the fuselage sides forward of this and do not put any vertical strengtheners (R5,R6,R7) in place...
Also omit the servo tray (I was moving mine elsewhere anyway.)

Stage2. Get a supply of finger clamps or clothes pegs ready. Treating one member of R3,R4 at a time you will find there is enough flex in them to be moved slightly vertically while remaining attached at R11. This was a real bit of serendipity. I moved them as far as i needed (see photos) and using PVA clamped and glued them in their new position.
Repeat this for all 4.

Stage 3. DO NOT throw away the matrix balsa sheet (76.02) the fuselage sides came from (you didn’t did you!). Why...... well the curved balsa infills you will need to make up the new fuselage sides on R3 and R4 are already there for you (clever eh...)...... see photo. Cut our and fix these as required.

Stage3. I decided I needed a square section at the nose in the old R9 position to be sanded down later to merge with the spinner.
To this end the thick balsa block holding the unused nose pieces has just enough scrap to include my
initial rectangular blank for my new nose block which will go where R4 was and behind the prop spinner. I will use the actual spinner to mark out a 30mm circle on the front face and sand to that when attached.

Stage4. Other issues. All planking top and bottom from R11 forward will need widening (but you will be well capable of that if you are building this sophisticated, delicate and detailed machine anyway). This also involves widening the removable hatch which I believe will fit quite happily after the above operations. As a side issue I have decided to make my hatch longer anyway to ease access to battery, ESC and servos all in one go. Do not forget to put in place any vertical ply strengtheners from the R5,R6,R7 set but these will all need to be a tad longer..... again the matric sheet of timber will help. The removeable hatch will need its clever vertical rails angle-ing a bit to match the new fuselage side internal width.

The overall result I find very pleasing as the width and height of the nose has not been enlarged to anything that spoils the natural taper of the fuselage from the tail boom forward and the mod uses no more materials than are already in the kit.
Photos will follow of the completed machine....

Best Regards..... Paul S

SLITE v 2

This is a superb 'builders' kit with laser cutting to die for. Its made by Gruner who also make the "INSIDE F5J" and the winging layout is very similar. I decided to fit a Haker A10-7L geared motor as launching aid. The fuselage needs another 5mm in height and 4mm in width at the nose to accommodate the motor. I used a 28mm VM spinner with a 13x8 GM prop also from Neil. The battery is a 3S 450mAh Lipo. I used Bluebird BMS101DMS servos which are the only ones that would fit under the wing. The same servo is a perfect fit in the spoiler bay. The all up flying weight with battery came out at 515g which included 10g in the fin to compensate for the motor wieght. I flew it for the first time today and am very pleased with the performance. Those of you who enjoy building will certainly enjoy the sheer the quality of this kit. The RC groups thread for the Slite is mainly related to the early version from a different manufacturer and not this v2 so don't be put off. Although there are no english instructions I had no difficulty understanding the superb colour print plan combined with the pictures in the manual.

Next day delivery and really excellent packing....the type you keep 'because it is bound to come in useful sometime..!' Lovely to see a coloured and highly detailed plan with all the parts numbered on both plan and wood.
The quality of the wood laser cutting is the best I have seen as is the quality of the balsa and ply chosen. This a a beautifully engineered glider. I would claim that you do need prior building experience even though the german instructions are well illustrated. All parts are of course cut to the correct size but the order of 'events' and the glues used will have an effect on the final strength and performance. I have not actually started yet because I have some repairs to do on my Bird of Time but the package is a great incentive to get them finished so I can get this obviously high performance machine into the air. I am investigating launches via a small electric motor 6" x 3" folding prop and ESC......these will not have to be to competition standard as I only sport fly. I think I will just about be able to fit same into the existing fuselage by slightly widening at the nose. The fuselage is 26 mm wide at that point so a 23mm dia motor from Hyperfilght should fit. I look forward to a theraputic build.

Slite v2

Firstly, I ordered this kit and some servos etc. and everything arrived next day in very sturdy packaging so top marks to Hyperflite.
I have built many kits over the years but this is by far the most precise and well designed kit using jigs rather then building over traditional plans. Everything was high quality and precisely cut. In general the model went together very well but it was fairly fiddly in places. The instructions are all in German so I downloaded a pdf and used google translate for each section which worked out fine. There are a few oversights in the instructions such as no mention of installing the wing locator pieces but nothing that can't be easily worked out by looking at the plans. One thing I found strange was having a removable stabiliser but the control linkages are glued in place with no snap link! Again something that is easily fixed but when so much thought and detail has gone into the design this is a little suprising to find.
I have installed 3 x ripmax sd100 servos but as others have mentioned in the online build logs they were installed further back then shown on the plan to allow space for the battery. It seems the design was originally based around a 1S lipo but moving the servos back makes has made space for a 800mAh NiMH. I had to also remove a small former (F4) in the wing to fit the spoiler servo and allow the spoiler to fully close.
The finished model is very light and looks fantastic (transparent Oralite shows of the intricate design). I've no doubt it will fly superbly but I haven't had a chance to fly it yet. I had plans to fly not only from a bungee high start but for light winds on the slope but it might prove to be a little fragile for slope use.
I have given 4 stars due to the complexities of changing things around (something I feel most people would need to do) but overall a fantastic kit that promises great performance.

I purchased the Slite V2 and the Pures V2. The quality of the kits and overall design is outstanding. These two models have been a joy to build. And of course, Neilís service is excellent. Order today in the states and receive your merchandise in less than a week. Great job!

Slite V2

It a complex and in places a very fiddly build, but it does make up into a high performance sailplane. The instructions are in German - I found that a translation was pretty much essential to building the model. The limitation on the instructions and the complexity of the build reduce my rating from 5 to 4 stars.
