Quote (google-translated): "The Bora glider model is a balanced design that meets the trend towards handy flying models in terms of size and design. The uncritical flight characteristics mean that beginners who want to get involved with RC gliding can easily use the model as a trainer. The Bora glider model is suitable for high takeoff. The model is designed in balsa and plywood construction. The largely pre-worked parts enable quick and easy construction. The model is suitable for installing a 2/4-channel radio remote control. RC function: rudder, elevator.

The construction kit contains all the printed or punched parts required for construction, control-tested strips, as well as connecting elements, rudder horns, rudder rods, canopy with lock, cockpit with figure, an RC installation plan (scale 1:1), as well as the construction instructions with the corresponding one Exploded view.

Quote (google-translated): "FMT presents: BORA R/C glider model for high take-off, overhill and slope flight, by Lars Waegner.

A surprise at the Nuremberg Toy Fair in 1974 was the first appearance of the Neuhierl toy factory, known under the brand name 'Carrera', as a manufacturer of model aircraft kits. You could get several 'almost finished' models there, including: to see the now proven sailors 'Favorit' and 'Draco'. This almost seemed to set the future development direction of Carrera models. A second surprise was this year's trade fair, at which this company presented some aircraft models in conventional balsa construction.

We have a good half a dozen established companies that have been producing model kits and accessories in large quantities for decades and are constantly modernizing their range. A newcomer in this circle of the 'established' naturally has a difficult time. If he cannot at least adapt the quality of his designs, the kits and their equipment to the established standard, his chances are very slim.

For this reason, it was with some curiosity that we opened the tastefully presented box of the kit. 'Bora' is a pretty glider model in all-balsa construction, intended for beginners and pure hobby pilots. With a wingspan of 2000 mm and a fuselage length of 1050 mm, it is one of the handy trunk models compared to today's standards. The wing is built in the 'open' je-deslky construction method, the tail units are boards, with edge arches glued across to prevent distortion.

Although a purely functional design, the model looks similar to an airplane, which is particularly emphasized by the crystal-clear canopy and the deep mock cockpit with a pilot figure. This makes 'Bora' an attractive father/son model, at least in terms of appearance.

Building kit and construction The equipment of the building kit is excellent, as is the prefabrication and labeling of the wooden parts. The construction plan is very clear, with many sectional drawings and detailed illustrations and is therefore not just an assembly plan. Its execution is one of the best we have seen so far (and there are certainly quite a few!). It is supplemented by separate construction instructions with numerous photos of the construction stages and fairly foolproof processing instructions.

A manufacturer who has so far mainly worked on plastic processing naturally has the machines, devices and know-how for the production of small plastic parts. So is e.g. For example, the canopy is not deep-drawn from acetate film, as is generally the case, but rather injection-molded and ready for installation. The locking mechanism installed is a small masterpiece. The cabin equipment, which is deep-drawn from ABS film, only needs to be trimmed at the edge and painted with plastic paint. The pilot's head is then glued in.

All other small parts have been taken into account. High-launch hooks, rudder horns, clevises, control rod connections and rudder hinges are injection molded parts of very good quality. The model builder only has to purchase additional adhesives, covering material and possibly paint.

The construction of the fuselage is made easier by carrying out all surface bonding exercises with contact adhesive and to assemble the side parts at the front are inserted into the precisely pre-cut nose block, while the frames snap into the corresponding recesses. The box hull is reinforced with three-dimensional strips and can be nicely rounded after assembly..."
