DRDesign 1/72 Lilienthal 1894 glider

DRDesign is a Brazilian firm that produces a number of photoetched items, among them several kits for planes of the Pioneer period in 1/72 scale.
The first photos show, alongside the Lilienthal model, the box of the 14 bis, a second model that I am also building for the same aviation enthusiast and colleague.
Although photoetching is an excellent medium to reproduce some aspects of a plane, not every element of it can be rendered with a convincing degree of accuracy.
The Otto Lilienthal Glider of 1894 is, however, a perfect subject for the media.
The box is made of flimsy clear plastic. The printed material seems photocopied.  Although the contents were unharmed, I wouldn’t put back anything inside, since the boxes are not robust enough, a malady suffered by other kit boxes too.
The metal parts are strong enough to endure the rigors of building, and the kit includes –besides the metal parts- instructions, a resin figure and some covering material. The resin figure is cast to an acceptable degree of realism, but will do better with a bit of attention, since it has some rough mold seams and a few minor resin blobs. The covering material intended to represent the fabric is white, silky and glossy. The instructions are adequate, but written in Portuguese and many of the captions are incomplete, as if they were inadvertently clipped. Nevertheless the images alone should be enough to guide you through. Some details are a tad unclear, especially in the rigging department.
A nice detail is that almost all the photoetched parts come already separated from their trees, all is needed is a quick swipe here and there to eliminate a spot of slight roughness.
There are many little holes through which the rigging has to go. Some of those needed to be opened since the etching process did not pierce them completely, but it was easy and uneventfully done with a very fine drill bit.
It is a nice little kit with a somewhat high-price tag (for what I saw on the net, around $55) that can become an apt reproduction of an iconic aviation history plane.
The parts were painted in a wood color and Mr. Smarty Pants Otto was painted too.
It is not clear how Otto should be connected to the airframe. A similar “Historic Wings” kit has some sort of braces for that purpose, but not this one.
The parts were airbrushed with a wood color, and once dry they were covered using a stick adhesive, since I was afraid the recommended diluted white glue would be too wet and wrinkle the paper. The holes were pricked through the covering. The vertical stabilizer was covered on both sides, then inserted through the stabilizer. The holding bar was inserted through the wing slots and the “poles” twisted to align them with the airflow and position the holes on the top to better receive the rigging.
The rib stiffeners that go on top of the wing were liberated from their fret. As said, the metal is stiff and kind of thick, so a good -and heavy duty- Xuron-type tool should be used to cut them free. The rough spots were then sanded. There are six of these baleens but only four are shown in the instructions. Since no scale plan/ 3view of the model is given, their position is a bit vague, only indicated by a perspective drawing that does not show if they run parallel to the airflow or somehow angled in a certain way. Since they may hinder rigging, I decided to glue them after I was done with it.
Once the structure was complete, I started to rig the model with very fine monofilament as per photos, but  the model could not stand the necessary tension of the rigging, therefore everything was undone and the model was re-rigged with thin steel wire.
Once completed the model looks quite nice. Given its fragility I posed it on small base with some “environment” details.
