NEW Unassembled electric glider KIT version - according to FAI F3 RES competition rules. Prime RES II E has 2m / 78.74" wingspan. Total model weighs ARC 300 grams / 10.58 oz. Laser cut ribs and all other required parts.

CLM Pro has released a new model called Prime RES II. The model is designed and produced according to FAI F3 RES competition rules.
Prime RES II is an upgraded version of Prime RES model. The new version has two spoilers. The fuselage is the same as on the Prime RES I.
The model is designed and optimized to the last detail and it all comes together perfectly. Most importantly, when flying and competing, adjustments can be done quickly on the spot (ballast, etc.)
All parts are precisely laser-cut from balsa and aero plywood, all carefully selected high-quality materials.
Due to its aerodynamic design and excellent performance, it is very stable and is a joy to fly.

Prime RES is a model for competitions, made according to FAI F3 RES rules . 

As the name says, the "Prime" model has, among other things a few new features and details, which include:
* safety mechanism for the joint between wing segments - no more glueing with tape on joints and other improvisations: one click and the wing is attached
* ballast: integrated box in the fuselage, with a few reserve ballast modules, which can be changed in the field in literally two seconds without disassembling the model
* angled carbon wing joiners mean there is no complicated crafting of the box for the joiner in the wings. You receive everything ready in the kit.
* all canopies have a mechanics with magnet for easier and faster closing
* other details worked out to the last bit

Kit includes:
- detailed drawing in color
- detailed building manual with step-by-step images
- CNC cut jig from styrofoam (underside of wings) for easier wing glueing
- laser cut ribs and all other required parts
- carbon tailboom
- carbon tube for mainspar with kevlar wrapped where wing joiners go
- carbon wing joiner and other carbon small parts
- vitroplast safety mechanism for locking the wing segments in place
- rudder horns, u-nuts and various bolts for mounting
- various magnets for the canopy, spoiler, ballast box and other
- bowdens and controls for connecting moving surfaces

Additional details for each segment of the model can be found below.


The wing is constructed so that the centerpanel is straight, while the middle panel and tip panels are angled. The wing is constantly an elipsis throughout its length which gives the model good stability and easy handling during flight.
The centerpanel is made as a single segment, the mid panel is another segment, and the two are joined with carbon joiners and have pre-prepared pins so that everything fits together perfectly.

An innovative advantage is the safety mechanism for the joint between wing segments - no more glueing with tape on joints and other improvisations: one click and the wing is attached.
Second advantage on the build is a pre-prepared wing carbon joiner made at an angle, so there is no complications of makin the joiner box in the wing.
Kits also includes a carbon tube which is used as mainspar, and is reinforced with kevlar where wing segments are connected.
You also get a CNC cut styrofoam jig for easier wing glueing.

The main construction of the wings is built with full balsa ribs, plywood for trailing edge and reinforcements where needed, while composite materials are used for leading edge and mainspar according to FAI F3 RES rules.
All parts are laser cut and fit together perfectly. So there is minimum rework needed, you only have to assemble everything and bond according to the manual.
The centerpanel comes with a two separated spoilers with built-in magnets so its perfectly closed when in closed position.

As our every fuselage, this fuselage is also made with aerodinymical shape with smooth transitions. Again, all parts are laser cut out of alsa and avio plywood.
The fuselage is reinforced on strategic spots with selection on material which gives it more strength.

Special attention was also given to the ballast, which is integrated within a box in the pod, with a few reserve ballast modules, which can be changed in the field literally in seconds without disassembling the model.

Canopy is designed in a way that there is enough space to easily manipulate with all components in the pod, allowing the battery to be inserted and connected easily, improving usability on the field.

The canopy has a mechanism with magnet for easier closing and making sure that it will not fall off during flight.

The tappered carbon tailboom is made from several carbon types. Materials are strategicaly oriented, so the boom has maximum strength and minimum weight.

The tail is also designed having aerodynamics in mind. It is a construction of laser cut balsa components. The connection between horizontal and vertical stab is reinforced with carbon.

Horizontal stab/elevator is fied to the tailboom via pylon which has a built-in nut so the tail can be dissasembled for easier transport.

Vertical fin has pre-prepared carbon pins which are inserted into drilled tailboom and is easilly fied to the fuselage.

We used A-tested resin, certified for aeroplane construction for all parts made od composite material.

Note: You can also order foil for model covering. We only use the highest quality Oralight foil from the German manufacturer Lenitz Prena Oracover Oralight.
