This is the Associated Reedy Sonic 540 Mach 2 17.5 Spec Motor. Reedy's return to the competition motor scene with their Sonic 540 was extremely successful on the track, as well as the showroom floor. Countless race wins at both the club and international level have proven the motor to be both reliable and powerful. Now, thanks to racing team and customer input, Associated and Reedy are proud to introduce the Sonic 540 Mach 2.Features:
- Optimized air flow
- High-strength balanced sintered rotor
- Silver-plated solder tabs
- Competition proven
- Ultra smooth, sensored operation
- Lightweight design
- Dual precision ball bearings
- Adjustable timing with alloy end cap
- Completely rebuildable
- 200mm sensor wire
- Built to ROAR, EFRA, and IFMAR specs
Small modifications have been made to the already competitive package to enhance its reliability, performance, and user-friendliness. A brand new alloy end cap replaces the plastic version, providing better bearing alignment and preventing accidental timing movement.
Strategically placed vent holes are now slightly smaller, reducing the chance of debris entering the motor while still maintaining excellent airflow. Internal changes include new silver-plated solder tabs to reduce power-robbing resistance and new bearing sizes to increase maximum RPM and improve reliability.
The high-strength precision- balanced sintered rotor remains the same as in the original model, with a variety of optional rotors available to fine-tune for specific applications and tracks. New 6.0, 7.0, and 8.0 models are now available for greater fine-tuning for specific conditions.
Several models for both stock and modified racing are available and all meet ROAR, EFRA, and IFMAR specifications.Includes:
