TracPlane

TracPlane, now available in its latest version 3.0, comes as a highly versatile tool for enthusiasts in the scale modeling community. With a compact file size of only 1.6 MB, TracPlane.exe ensures efficient performance without burdening system resources. Developed by J-C. Etiemble, this program caters to users running Windows 7, 8, 10, and 11, making it accessible to a wide audience.

Falling under the Photo & Graphics category and specifically into the 3D Design subcategory, TracPlane provides extensive capabilities for calculations and sketches associated with scale models. The software allows users to precisely outline input data for various components such as wings, stabilizers, fuselages (both glider and plane), fins, and rudders.

Users can choose between glider and plane fuselages, create intricately detailed wings with up to five panels using custom airfoil files, and perform complex computations including tail volume ratio, Reynolds number, and the theoretical balancing position of the model. The program also supports exporting all data into DXF or TXT file formats, facilitating seamless data transfer and sharing.

One can download TracPlane for free, which is a major advantage for modelers looking for a cost-effective yet powerful design tool. The application is not just limited to version 3.0; earlier versions such as 1.8 and 0.9 are also available, offering flexibility for those who might prefer or need to use an older iteration.

Pros:

• Free to download and use.
• Compact file size of 1.6 MB.
• Comprehensive features for modeling different aircraft components.
• Export options in DXF and TXT file formats.
• Supported on a wide range of Windows OS versions.

Cons:

• May have a learning curve for new users.
