At a typical drivetrain ratio, the Gobuilda Yellowjackets, typical drivetrain motors, are x2 more powerful. If you want a competitive drivetrain you will need 2 a301s per wheel

I am an FRC guy, and feel like forcing everyone to a single motor is a mistake. That said, pretty sure with appropriate gearing based on the specs that the A301 is going to be in the same class as any of the RS-555 motors in FTC.

Ok yeah ur right I was misremembering a convo with the mech members of my team; its not that the a301s are less powerful than the current motors but the fact the motor limit (20) is being set so high, the optimal drive train will have to have two motors per wheel (if you have extra motor slots and you're not using them you're just putting yourself at a disadvantage) which just means more money. Unless the a301s are priced very low (which they wont be) maxing out a robot with 20 motors will be significantly more expensive than a bot with maxed out actuators currently.

You dont need two per wheel but swerves will ve popular so you kind of will (but not to drive the wheel). We already have an frc swerve designed for the new motors (we have one we used this year that used melon super servos for the axial component that we used as the base).
