Every step from raw fibre to flight-ready blade happens at our Banda facility. No outsourced layup, no third-party balancing, no opaque QA — which is why we can publish our tolerances.
Every incoming roll of pre-preg or batch of resin is tested for fiber-volume fraction, glass-transition temperature, and cure profile against the lot spec. Material that fails the coupon test never reaches the layup floor.
Hand layup for low-volume bespoke runs and tooled layup for production SKUs. Vacuum-bagged cure at controlled ramp. We track every blade against its layup card.
Net-shape trim on a 5-axis CNC for blade root and tip geometry. Hub-bore tolerance is held to ±0.02 mm.
Two-plane dynamic balancing to ISO 1940 G2.5 for standard SKUs, G1 for premium SKUs. Imbalance is corrected by mass-removal at fixed correction points (never by adding tape).
Each design is characterized on our 0–25 kgf bench across the design RPM range. Production blades are batch-sampled against the master thrust curve.
For platforms where acoustic signature matters — surveillance, agricultural spraying near livestock, residential delivery — we measure SPL and tonality in a semi-anechoic enclosure.
Every blade is laser-etched with its batch ID. Each shipment ships with a balance certificate, the thrust-curve reference sheet, and the batch coupon test results.
We work with defence and commercial UAV integrators on custom propeller designs. Send us the platform spec and the duty cycle — we'll send back the production options.
