RC plane Design Lab
Type in your own design and get a full analysis report: neutral point and CG, tail size, stall speed, drag, flight time, wing strength and a design score with what to fix. See it in 3D, compare it with our planes, and save the report as a PDF. Nothing is uploaded: your design stays on your computer.

What the numbers say
How it works: wing and tail geometry, lift slope (Helmbold), neutral point with tail and fuselage effects, a drag build-up of wing, tail and fuselage with span efficiency, battery power at η 45 % with 88 % of the pack used, and spar bending at 4 g. The method is checked against the full NeuralFoil + lifting-line reports of our Koonj and Chakor. These are design estimates: always check the CG on the real plane and test fly with care.
Questions
Is my design uploaded or shared?
No. The Design Lab runs completely in your browser. Your sizes are not sent to us or anyone. Saved designs stay in your browser, and a share link carries the design inside the link itself.
How accurate is the analysis?
It is a quick design estimate, checked against the full NeuralFoil and lifting-line reports of our Koonj 1650 and Chakor 1300: within about 2 % of the mean chord for the neutral point, 1 km/h for stall and about 5 % for drag and flight time. Always check the CG on the real plane before the first flight.
What does the design score mean?
It adds up six checks: pitch stability (25), tail size or flying-wing trim (15), stall speed and wing loading (20), efficiency L/D (15), flight time (10) and wing strength (15). A serious problem, such as a CG behind the neutral point, caps the score.
Which layouts can I analyse?
Conventional tail, T-tail, V-tail and flying wing, with straight or tapered and swept wings, any airfoil from the list, and LiPo or Li-ion packs. Foam, balsa, built-up, composite or 3D-printed airframes.
How do I get the PDF report?
Press Download PDF report and choose Save as PDF in the print window. The report has the score, what to fix, a 3D picture, the top view with CG and neutral point, all results, the power chart and the comparison with our planes.
