Arrowmax have introduced a dedicated transmitter battery pack for the Sanwa M17 radio. The 3.7V 6000mAh LiPo replaces the standard battery with a high-capacity pack for longer operation time and thus more confidence even when having long days at the track. The battery measures 86x44.5x10.5mm and it comes pre-wired with a universal JR-style plug.

v2 version, new dimensions for perfect fit.

EDS Tools represent some of the finest quality tools you can buy. Top materials make for 
reliable use and long life.

The next-generation tool for motor testing and tuning from Hobbywing!

This tool is used to test the brushless DC motor and its internal components. It can measure the Kv value, rpm, current, end-bell timing and sensor elements of the brushless motor. These parameters can be is played on the LCD in real time, so that you can have an intuitive and full understanding of the motor used. In addition, the built-in Bluetooth of the Tunalyzer can establish communication with the esc through the mobile phone app to realize the parameter setting and firmware updating of the esc.

Automatic Test Mode
The Tunalyzer allows you to run auto-testing modes to provide quick and easy tests.
Accurate current readings - within 0.01A

Timing, rotor, and signal accuracy within 0.1degrees
Accuracy is achieved by gathering more information and providing more data for the Tunalyzer to review.

Stable Voltage Regulator
The Tunalyzer has an internal voltage regulator to allow repeated tests at the same voltage as the battery pack discharges. This allows testing to be done on several motors for direct comparisons.
(Tunalyzer has "Preset" voltages for this feature that must be used and the battery must be greater than the set voltage.)

Manual Test Mode
The Tunalyzer can be used as a manual tester for simple bench top checks. Forward and reverse with 100% linear throttle. The live output of the data is displayed as well.
(The motor pole must be set after starting the "Auto Motor Test" for the first time.)

Multi-Function Control Dial
The dial on the face of the Tunalyzer is used for throttle control as well as external testing.
PWM output is offered for use to test Servos and ESCs on the bench.

RPM Displayed in Real Time
The Tunalyzer provides a motor pole setting from 2-60 pole motors. This allows for an accurate and precise display of motor RPM in real-time.

3 inch Colour Touch Screen Display
Ultra crisp and clear full-colour touch display allow for an extremely quick and easy-to-learn interface. Easy to read and use.

OTA Tuning and Upgrades
The Tunalyzer can double as your ESC programmer device for simple bench top ESC tuning.
With the HW Link App, your favourite smart device can be used to connect via Bluetooth to the Tunalyzer.

Multiple motor types supported
Sensorless and Sensor motors can be tested. Virtually any pole count or style of a brushless motor can be tested with the Tunalyzer.
(Sensorless motor characteristics may differ from sensored motor results. The test data is only available in specific item. See the instruction manual for details.)

Built-in Reverse Power Supply Protection Circuit, Strong Security
Built-in reverse polarity protection circuit. Equipment will not be damaged by an incorrect battery connection.
