Motor or ESC failure is often caused by heat!
Heat and electronics do not mix.  Electronics are more efficient and reliable at lower temperatures. Running your motor and ESC as cool as possible is always a good idea. If you keep them cool, they should last longer and most likely increase your runtime.

Right Temperature for Peak Performance
In all forms of powered RC gearing, the operating temperature of the main driving motor or engine is an important factor to consider for longevity and performance. The correct operating temperature will depend on the load or conditions the motor/engine must drive.
The operating temperature for gas, nitro engines has different characteristics and impacts on overall performance. Therefore, it’s essential to understand the specific requirements and optimal operating temperature for your particular motor or nitro engine to ensure that it operates at peak performance and lasts as long as possible.

Know The Heat Before It Destroys Your RC Equipment
When it comes to RC racing, Motors, speed controllers and batteries are some of the most expensive components. Most RC hobbyists, even gurus, have blown up one of these at some point and know the feeling of burning dollars to replace it or waiting weeks for repair.

Set Up with Data, Not Guess work.
Checking the motor’s temperature is the most effective way to keep it from burning out.
The usual way to check your temps is to get a temp gun. However, such a thermometer can only give you an instant reading at a time. And it can never measure and save the continuous, ever-changing thermograph during the real RC runtime!
To make an educated decision on Set Up, SkyRC introduces Thermologger Duo to record and generate a visual thermograph!

Dual Channel & RC Expert Grade Accuracy
The Thermologger Duo provides precise temperature measurement with a rapid response time. Its accuracy ranges from ±2.0℃(35.6℉) for temperatures between -20℃(-4℉) and 100℃(212℉) to ±2% for temperatures over 100℃(212℉). With K-type thermocouple temperature sensors that meet industrial standards, RC drivers can easily measure contact temperature on various components, such as motors, ESC, heatsinks, and wires. The dual-channel feature of the Thermologger Duo allows drivers to measure two different contacts simultaneously, effectively making it a portable two-channel telemetry thermal station!
The Thermologger Duo boasts a wide temperature detection range of -20℃-210℃（-4℉-410℉）, and its sampling interval is adjustable from 1 to 5 seconds, making it suitable for most RC uses.

Measure on The Go!
With its built-in Bluetooth, the Thermologger Duo allows instant communication via a mobile app, saying goodbye to cables.
Through the RC Gears app, you can easily read data, check thermographs, and troubleshoot problems, all while building successful modifications and maximizing runtime.
Using the free app, you can capture mechanical, electrical, and thermal measurements from this wireless-enabled thermologger. Measurements can be saved to your records, and you can reference them anytime from your smartphone, tablet, or desktop.
Additionally, you can conveniently share measurements with other RC drivers via text or email, showing them exactly what you’re set up is.

Easy to Use
Thermologger Duo is designed for easy installation in the field. The two pairs of 30 cm thermocouple wires are cut-to-length for many applications.
The set also includes high-quality copper foil stickers with excellent electrical conductivity, adhesion, flexibility, and temperature resistance. The stickers are made of flexible copper that can adapt to almost any shape.
Mount the logger with a fastener, cut the wires, and mount with a sticker; you are all set!

Better Over Time
The App will prompt whenever an update is detected! You can update the firmware to Thermologger Duo over OTA(On the Air), thanks to Bluetooth!

Tiny with a Long Battery Life
Thermologger Duo is compact in size, but it boasts a long battery life. It is powered by a CR2450 coin cell battery, which is included with the device and lasts for approximately ninety-six hours of continuous work* under normal operation. When the battery eventually runs out, it can be easily replaced.
*A ninety-six hour battery life is tested by SkyRC labs. There may be some slight differences in the battery life for different batteries and scenarios. Please refer to the actual product for it.
