⭐⭐⭐⭐⭐ James Wilkins - Marine Survey Drones LLC
"We've integrated the JRDT 100cc Pro Model into our coastal inspection drones, and the performance has been outstanding. The water-cooled system keeps the engine stable even during 90-minute missions in saltwater environments. We customized the mounting brackets and fuel mapping for our airframe—something the supplier supported seamlessly. Power delivery is smooth, and the 8.5 HP output gives us the agility we need for rapid repositioning. After 7 months of near-daily use, zero failures. This is a professional-grade engine that justifies its price."Purchase Date: February 2024 | Usage Period: 8 months
⭐⭐⭐⭐☆ Lena Patel - DIY Surfboard Builder
"I built a motorized surfboard using the JRDT 100cc Base Model, and it’s been a game-changer. The aluminum alloy body looks sleek and hasn’t corroded, even after frequent use in the Pacific Ocean. Installation took a weekend—thanks to the pre-labeled throttle and fuel lines—and the engine starts reliably every time. It’s a bit noisier than I expected (around 85 dB), but that’s typical for two-strokes. For hobbyists who want real power, this is the best option I’ve tested."Purchase Date: October 2024 | Usage Period: 5 months
⭐⭐⭐⭐⭐ Dmitri Volkov - Arctic Drone Systems
"We operate in extreme marine conditions, and standard air-cooled engines kept failing due to overheating. Switched to the JRDT 100cc Advanced Model with liquid cooling and 7075-T6 alloy housing—massive improvement. The engine maintains optimal temps even during 2-hour polar patrols. The modular gear system allowed us to fine-tune propulsion for ice-edge navigation. Customization took an extra 3 days, but it was worth it. Certified to IPX7 and ISO 9001, which gives our clients confidence. This engine is built for mission-critical use."Purchase Date: May 2025 | Usage Period: 3 months
⭐⭐⭐⭐⭐ Marcus Lee - Drone Racing Enthusiast
"I’ve been building drone-powered mini boats for local races, and the JRDT 100cc Base Model is my new go-to. Lightweight at 4.2 kg, it doesn’t bog down the hull, and the two-stroke punch delivers quick acceleration off the line. I adjusted the gear ratio per the guide, and now I’m consistently top three. The fuel injector is precise—no sputtering, even at full throttle. After 4 months and 20+ races, only routine cleaning needed. Aluminum body shows zero rust. Highly recommend for competitive builders."Purchase Date: January 2025 | Usage Period: 6 months
⭐⭐⭐⭐☆ Elena Rivera - Coastal SAR Unit
"We tested three engines for our rapid-response drone boats—this one won. The Pro Model’s 30% longer runtime due to water cooling was decisive. In real deployments, that extra 15 minutes has already helped us reach two swimmers in distress. The overheat protection kicked in once during a high-wind mission, preventing damage. Only downside: refueling every 15 minutes under max load is a logistical challenge. But reliability? Flawless. We’ve deployed it over 40 times since April 2024."Purchase Date: April 2024 | Usage Period: 11 months

Dr. Alan Foster - UAV Marine Systems Specialist
"The JRDT 100cc series sets a new benchmark for two-stroke water-cooled drone engines. Its power-to-weight ratio (2.02 HP/kg on Pro Model) exceeds most competitors, and the use of 6061/7075 aluminum alloys ensures durability without compromising payload. I particularly appreciate the customizable mounting and fuel mapping—this level of adaptability is rare in sub-10 HP marine engines. For any operator needing reliable aquatic propulsion, this is now my top recommendation."
Karen Zhou - DIY Watercraft Design Advisor
"Among 100cc engines for hobbyist builds, the JRDT stands out for ease of integration and corrosion resistance. The pre-configured throttle body and fuel injector reduce tuning time significantly. I’ve recommended it to over 30 clients building motorized surfboards or RC boats—none have reported failures. For home users, the Base Model offers exceptional value. Just ensure proper cooling water flow during extended runs."
