Tell us what you are building. We configure our market-ready controller for your motor and operating requirements, validate it on real hardware and on your platform, and deliver a manufacturable design with the evidence your certification needs. UAV propulsion is one example, alongside robotics and industrial drives.
For manufacturers of BLDC-powered products, including UAVs and high-dynamic electric drives · Germany, Austria, Switzerland and the EU

Every phase ends in something you can hold, read or sign. Nothing is left to the final week.
Weeks 1–2
What happens
Capture application, motor, load, power source, environment, safety level and manufacturing target.
You get
Requirement sheet signed by both parties.
Weeks 3–8
What happens
The controller configured for your motor, load and power source; integration with your platform agreed.
You get
Configuration proposal and integration specification.
Weeks 9–14
What happens
Prototypes built and configured; bench tests on real hardware, including thermal, switching and EMC pre-compliance.
You get
Prototype units; bench test report.
Weeks 15–22
What happens
Validation on your motor and load combination; environmental and fault tests; application-specific campaign such as flight or dynamometer testing.
You get
Validation report for your certification file.
Weeks 23–26
What happens
Manufacturing package and production test support for your chosen manufacturer; licence terms for series production.
You get
Manufacturing package; licence agreement.
A new controller normally means a 12 to 24 month design and revalidation cycle. Four things remove most of it.
The controller already exists and is market-ready. Your variant is a configuration for your motor, load and power source, not a new development.
The controller has been validated on real hardware. Your pilot adds validation on your own motor and load.
Every phase produces test reports and traceability for your certification file, not paperwork bolted on at the end.
Delivered as a licensed binary. You configure it for your application; you do not have to rewrite it.
Your product stays yours
We never compete with your supply chain. We license the controller; you own the product you sell.

Sparrow Quest is a power-electronics company in Sindelfingen, Germany. We designed and built a market-ready, high-dynamic BLDC motor controller, first for UAV propulsion, and we support customers across the DACH region with application engineering.
This is phase 0, step one. Tell us about your platform and we will come back with a configured design proposal and a pilot scope.
Limited places in the 2027 cohort. The first pilots start in Q1 2027.
