Last year when the NEO and SPARK MAX came out we held off on using them because we were hesitant to use an untested product. At the beginning of the season this year we wanted to make the jump into brushless motors, and we were presented with the option of NEOs or Falcons. Because of our familiarity with the CTRE ecosystem, we decided to go with Falcons. In general we’ve been pretty happy with their performance so far. While there’s no real problem with switching to REV’s brushless ecosystem in the future, it’s a lot easier to stick with CTRE’s if there’s no reason not to.
We’ve been using 775pros on most mechanisms for the past 3 years now. We’re happy with how they work, and we have a stockpile of them and Talon SRXs to drive them. We would need an absolute encoder to measure the module’s angle anyway, so when comparing the cost of using different motors we really only need to look at the true motor cost. In that case the Falcon is a lot more expensive than a 775pro, even before you account for the fact that we already have a stockpile of 775pros whereas we only have enough Falcons for this year’s drivetrain. While it may be true that using a NEO, NEO 550, or smaller brushed motor would be slightly lighter than a 775pro and associated gearing, I’d say it’s worth it for the familiarity and not needing to stock special motors.
I don’t have anything to do with this design, but from the CAD model it’s a 4" AM performance wheel.
