Respectfully, I disagree here. The TalonSRX was released multiple years ago to work with brushed motors (i.e. CIM, Mini CIM, 775 Pro, etc…) and has been established as reliable and efficient. On the other hand, the Spark Max presented the opportunity for using both brushed and brushless motors (only Neo for now) and was released at the beginning of this season — with quite a few initial software bugs coming with. This year my team used 7 NEOs on our robot and couldn’t have been happier: they weigh much less than the comparable CIM motor, they are more compact, they generate less heat, and they can run at low speeds (due to the fact that they’re brushless). You can read here on the diffferences between brushed and brushless motors.
Again, I disagree that this would be the seventh way (it would be the second way after Spark Max). Although the Spark Max already has surfaced and been tested, my team will still be keeping an eye out for the brushless Talon SRX model. The model could 1) create competition for the Spark Max, improving quality and reducing prices, 2) present new opportunities like connecting an encoder in addition to a brushless motor, and 3) encompass the existing Talon SRX ecosystem with CAN which has been tested extensively and provides functions such as Motion Magic.
While I don’t think that my team will switch over to the CTRE version in the 2020 season (as we already invested in Spark Maxes and tested the Spark Maxes throughout the season), it will definitely be considered for future years in my opinion.
