Real-Time Digital Telemetry Bus Integration for UAV Health Monitoring
Summit series electronic speed controllers stream real-time operational telemetry over digital serial buses to onboard autopilots. Flight control computers track MosFET temperatures, bus voltage, phase current, and instantaneous rotor RPM.
This telemetry enables ground operators to detect thermal saturation early and execute automated return-to-launch procedures before batteries deplete.
Electrifying Heavy Industrial Drones: Transitioning from Gas to GA Motors
Dualsky GA series industrial powerplants provide direct electric replacements for 15cc to 100cc+ internal combustion engines on survey and cargo drones. Eliminating liquid fuel tanks removes contamination risks, reduces airframe vibration, and minimizes acoustic and thermal visibility.

The Dualsky XC speed regulator family utilizes heavy-copper multi-layer PCB layouts coupled with ultra-low equivalent series resistance (Low-ESR) capacitor banks.
This topology dampens voltage spikes during high-frequency PWM switching, preventing RF interference from degrading telemetry and satellite navigation link budgets.
Maintenance Protocols and Bearing Replacement for Dualsky Powertrains
Ensuring long-term propulsion reliability requires adherence to scheduled maintenance intervals. Stator windings should undergo visual inspection every 50 flight hours to confirm enamel coating integrity and check for shaft play.
When bearing wear is detected, replacement with genuine Japanese NMB or NSK bearing sets restores factory operational tolerances.
