Cost-effective prototype instrument in development

Turn vibration data into a clear correction.

VectorTrim is a portable, guided dynamic-balancing instrument being developed to capture RPM, vibration amplitude, and phase—then calculate a practical correction from a controlled trial run.

Designed to close the affordability gap Development target below $2,000—well beneath many multi-thousand-dollar professional systems.

The missing middle

Serious balancing capability without the usual price barrier.

Many owners, builders, and small maintenance shops could benefit from owning a balancing instrument, but cannot justify a full commercial system for occasional use. Dedicated aviation balancing packages can now cost several thousand dollars, leaving a wide gap between improvised methods and professional equipment.

VectorTrim is being developed to fill that gap: a dedicated handheld instrument focused on the core balancing workflow, without the cost and complexity of a broad laboratory-grade vibration platform.

Its design is informed by hands-on use of established commercial rotor-balancing equipment, with emphasis on the capabilities an owner, builder, or small shop actually needs in the field.

A focused field workflow

Three steps from vibration to correction.

VectorTrim is intended to keep the arithmetic, vector plotting, and run-to-run recordkeeping inside the instrument—so the operator can stay focused on setup and repeatability.

Capture a stable baseline

Run at the selected operating speed while the instrument evaluates RPM stability, vibration amplitude, phase, and sample quality.

Apply a known trial weight

Enter the trial-weight amount and angular location, then repeat the measurement under the same operating condition.

Install the calculated correction

The influence-vector calculation produces a correction amount and position, ready for a verification run.

Made for the work area

No laptop balanced on a toolbox.

A battery-powered instrument, touch-guided procedure, visible measurement quality, rugged sensor packaging, and a remote capture button are central to the design.

Planned capabilities

Pay for the balancing job—not an oversized analysis platform.

The current prototype brings sensing, workflow, calculation, and result presentation into a single field device, with the feature set deliberately focused on practical balancing.

Live vibration measurement

Clear display of amplitude, phase, RPM, stability, and sample confidence.

Influence-vector calculation

Baseline and trial measurements are converted into a recommended correction vector onboard.

Guided touch workflow

Prompts help keep each run consistent and reduce missed setup information.

Optical tach input

Reflective target sensing provides the angular reference required for phase measurement.

Portable operation

Rechargeable battery power and a persistent charge indicator support field use.

Protective enclosure

A handheld case and wraparound bumper concept are being developed around the electronics.

Designed around the cockpit

Field hardware that respects the job being done.

Rotor balancing is not a bench exercise. The sensor must mount securely and survive vibration, while the pilot must be able to capture a measurement without releasing the flight controls.

PLANNED SENSOR PACKAGE

Rugged cylindrical accelerometer

The production sensor concept uses a compact metal housing, full potting, visible sensing-axis mark, strong strain relief, a long shielded cable, and a secure threaded or adapter-based mount.

Potted electronicsShielded cableSecure mountingClear axis mark

HANDS-ON-CONTROLS CAPTURE

PTT-style remote measurement button

A small momentary button can be secured where the pilot can reach it without taking a hand off the controls. One deliberate press triggers or accepts the measurement, with clear visual and audible confirmation.

Independent American small business

Designed, developed, and assembled in the USA.

VectorTrim is being created by a small independent American business—not commissioned as a generic mass-market device. Choosing VectorTrim supports continued hands-on development, careful small-batch assembly, and direct product support from the people behind the instrument.
