Service

We provide technical development, custom part manufacturing, and material testing for projects in wood,

metal, and aviation engineering. Our services include tensile, compression, and bending strength testing,

detailed workshop reports, and moisture analysis using the Darr method.

In the field of experimental and light aircraft, we deliver custom-made wooden ribs, rib assemblies, and precision structural components – crafted with technical clarity and skilled workmanship, from concept to final solution.

Pietenpol Air Camper Kit – Wooden Aircraft Parts for Experimental Builds

We offer the Pietenpol Air Camper Kit as a wooden kit for experimental aircraft, available either as a complete package or in individual components. All parts are handcrafted with care and based on the original plans. In our shop, you can choose from:

Fuselage structure
Wing assemblies (complete or individual)
Wing ribs
Spars
Ailerons with center spar
Rudder and elevator
or custom parts as needed

All components are built using classic wooden construction and are ready for direct use in amateur-built aircraft – including documentation for individual inspection and approval.

Our shop is currently being updated – full component listings and prices will be available soon.

Tensile strength

Tensile strength testing of wood is carried out in accordance with DIN EN 408. Standardized specimens are used (250 mm gauge length, 70 × 14 × 5 mm

cross-section). Moisture content is determined in advance using the Darr method. Test samples can be provided by us or submitted by the customer. A compliant evaluation is only possible with properly documented moisture data.

Bending strength

Bending strength of wood is determined according to DIN 52186. Test specimens measure 20 × 20 mm in cross-section and 320 mm in length, with a support span of 280 mm. Moisture content is determined in advance using the Darr method. Samples can be prepared by us or submitted by the customer. Norm-compliant evaluation is only possible with documented moisture content.

Compressive strength

Compressive strength of wood is tested according to DIN EN 408. Standardized specimens (13 × 13 × 13 mm, 169 mm² cross-section) are loaded axially, parallel to the grain. Moisture content is determined beforehand using the Darr method. Samples may be provided by us or the customer. A norm-compliant evaluation requires documented moisture data.

Wood imports of
Sitka spruce
Nordic pine

We supply high-quality Sitka Spruce from the USA and Canada – specifically selected, tested, and ready for use in aircraft construction. All wood is inspected for moisture (Darr method) and tested for tensile, compression, and bending strength according to current standards.

This ensures a smooth start to your project – with no delays, rework, or surprises during inspection.

Custom Manufacturing in Experimental Aircraft Construction

We manufacture ribs, spars, control surfaces, and fuselages from wood – each one crafted by hand with care and precision. Every component is a custom-made one-off, based on CNC-milled templates to ensure perfect fit and repeatable accuracy.

Our parts are built to the highest standard – cleanly finished, weight-optimized, and technically traceable.
Workshop reports, test protocols, and material certifications are always included.

We use only wood that has passed Darr method moisture testing as well as tensile, compression, and bending strength tests.

Product Design & Custom Manufacturing for Experimental Aircraft

Great design takes off long before the aircraft does.
In experimental aircraft, every gram, every line, every function counts. Here, design is not decoration – it's part of the engineering: functional, lightweight, and precise.

We offer custom product design and one-off manufacturing in wood, aluminum, and carbon laminate – from cockpit details and interior solutions to load-bearing structural components.

Collaboration with certified inspectors is an integral part of the process. All components are documented, tested, and prepared for individual inspection and approval according to experimental aircraft standards.

The focus lies on combining tradition and innovation – for example, through the modern and airworthy use of classic materials such as wood and fabric.

Precision in 3D

Precision begins in the digital space.
As a CAD and 3D designer, I translate ideas into tangible digital forms – accurate in detail, true to scale, and ready for realization. In aviation, it’s not just about the concept, but about technical precision. Using state-of-the-art CAD systems, I design components and complex structures that meet the highest standards of aerodynamics, manufacturability, and functionality.

From the first volume model to production-ready construction, each digital representation is developed in close coordination with engineering, manufacturing, and design – thoughtfully refined down to the last contour. Throughout the process, the focus remains on lightweight construction,

material efficiency, and technical feasibility. Whether for prototypes, small series, or individual parts – my CAD work combines design quality with engineering depth. For constructions that not only look good on screen, but perform flawlessly in reality.
