Basis: Design rules and figures from the cited sources; example geometry by Xem Studio
Catalog version: 2026-10-20

Sizes: see table below
- APC publishes suggested maximum RPM as a constant divided by diameter in inches, so bigger props have lower limits (APC RPM Limits).
- Glow/sport props: 190,000/D; thin electric: 150,000/D; folding: 120,000/D; multirotor: 105,000/D; slow flyer: 65,000/D. A 10x6 glow prop should stay under 19,000 rpm (APC).
- Electric-only props lack the strength for glow engines' firing pulses, though glow props can be used on electric motors (Model Aviation, APC Q&A).
- The file is a reference example built by Xem Studio from the numbers above. Sizes the sources do not fix are illustrative; scale the example to your own vehicle.
