Quicrun Fusion PRO system (2in1) for Crawlers

All-in-one design for optimized length

The design has been integrated and optimized to provide a cleaner and
sleeker layout appearance. The overall length is now at 58mm and is
6mm shorter than the previous version. Thesmaller footprint has the same
length as the AXE540L motor to provide for a spacious and an easy
assembly process.

High Driving Efficiency for Long Battery Life

The FOC drive upgrade increases its entire power system efficiency by 8%while the power consumption loss
is reduced by 30% compared with the previous generation.The new 2300KV fusion is significantly more
powerful than the previous 1800KV version with an even lower temperature rise while climbing at low speed.

FOC (Field-oriented Control) for
Super Linearity, HighTorque and
extremely silent system

The Fusion system adopts the FOC mode and operates smoothly at low
speed. The strong torqueis able to outperform the sensored power system
and is better and more consistent than the brushed power system. The
latest generation motor is extremely silent, eliminating unwanted
noises during operation and is the best choice for rock crawler.

Super Linearity

Intelligent Torque Output & Speed Closed-loop Control for Easy Control

The Fusion system is equipped with Intelligent Torque output and Closed loop speed control to maintain
the motor’s RPM as the vehicle conditions changes. Regardless of going uphill,
downhill or underload, the intelligent output torque senses the operation and allows for simple operation.

Intelligent Torque Output

Note: When the running mode is set to normal mode,
there is no fixed speed function, similar to the effect of brushed system.

Applicable to All Weather & Track Conditions

The IP-67 waterproof of the whole power has excellent waterproof and dustproof
performance. The whole power can easily drive on the muddy, sandy, icy,
snowy and water track under various weather conditions.

Refine parameter items

The ESC is equipped with 13 adjustable parameter items to meet the needs of fine-tuning
adjustments. New parameters such as "MAX. Brake Force", "RPM Decrease Rate ", "start
mode ( Punch)", "Neutral Range" and other practical parameters are included.

Professional Drag Brake Adjustments
& Super Parking Capacity

Fusion pro is equipped with 8-speed drag brake force and 9-speed drag brake-rate
adjustment to meet the needs of different models, different field and different handling
habits. The maximum drag brake force is about twice of that to the brushless power
system of the same size, providing superior parking capability on the slope.
