Arrowmax Dash R-Tune 540 Sensored Brushless Motors are 540-size Competition grade motors, developed around a high-airflow can. The goal is to provide the best feel and great power on the race track. Huge cooling openings around the front section and machined openings around the stator increase airflow to keep the motor cooler towards the end of a run - helping to reduce fading and deliver more stable performance. An updated stator further adds to the overall performance with increased torque and reduced heat build-up.

Arrowmax Dash R-Tune 540 Sensored Brushless Motor (17.5T)
This motor certainly looks the business. Attractive machining and anodized details certainly help it stand out. It includes aluminum screws to swap out the steel ones if one so desires. For all the detailing and excellent fit and finish it is also at quite an attractive price point. My experiences with this motor have unfortunately not quite lived up to initial expectations. While I have only used it in 17.5 stock 2wd buggy, (indoor carpet) tuning with gearing and timing over the course of several months has not yielded competitive results with respect to other offerings in this category. It did not run abnormally warm nor did it show premature fade but it simply did not deliver the torque or conversely the top end commonly found with motors in this class respectively. My opinion is that it may be more suitable to other types of vehicles that I have not had the chance to test it in. While this may or may not be the same experience others have had, I can’t say for certainty that this would be a good choice for 17.5 stock class racing within the confines of my competitive environment. But damn it looks good.
