The EzRun 3665 SD G3 features an improved water- proof sensored cable interface and an upgraded sensored mode to achieve motor temperature protection and perfectly matches the EzRun MAX10 G2 ESC. The high-precision Hall sensor components ensures that the rotor position output is always accurate and consistent, achieving excellent linearity and a great throttle control. The EzRun 3665 G3 motor adopts a high precision bearing that is waterproof in the front end of the motor. The rear end of the motor uses precision iron cover with a smaller structure to improve the capacity, and at the same time, provides a higher bearing speed while keeping resistance low. The operation is smoother and more reliable. Compared to the G2 motor, the motor temperature is greatly reduced under the same load conditions. The overall efficiency is 3% more effective while the maximum output power has increased by 5% All the materials used on the EZRUN 3665 G3 motor (Motor casing, bearings, ultra-thin silicon steel sheets, high temperature-resistance copper wire, explosion-proof rotor, high-tolerance alloy shaft) are carefully selected and approved by our in-house engineers. Hobbywing is serious in providing users with an extraordinary performance for a long period of time. The motor adopts a modular detachable structure design for easy disassembly and daily maintenance. This helps to prolong the lifespan of the motor and maintain- ing the efficiency of the motor simple. The IP-67 waterproof system guarantees excellent waterproofing and dustproofing protection. The whole power system is able to drive on a variety of surfaces including mud, sand, ice, snow and water without damaging the power unit.

sleeves long
I'm 5'6" and stocky but the sleeves are too long and slip over to rest half way down my hand. If your 5'9 or taller you will be fine.

Great Lightweight Pullover
Color: Faded Denim Heather, Size: X-Large
I'm 5’8” and about 240 lbs, and I went with an XL for this light grey quarter-zip pullover. Fit is spot-on, not too tight, not overly baggy. The material is lightweight and breathable but still feels like it has some substance, making it perfect for layering or wearing on its own in mild weather. The fabric has a nice stretch to it, which adds to the comfort and ease of movement, and it holds its shape well. The zipper is high quality, smooth to zip and feels durable. Color is true to the description, a clean, versatile light grey that pairs easily with joggers or jeans.
