Not true nuz69. IT has not been bad for efficiency in our years of testing the clutches in our many brushless racing vehicles (truggies included). Our bearings last many times longer compared to a nitro clutch and this is with standard cheapo bearings. There are way more issues involved with running a pinion directly connected to the drivetrane with no disconnect like a slipper or a clutch. A pinion directly relays all of the initial torque of motor start up and under braking the issue is compounded. This relay of torque is moving out to the driveline components like outdrive cups and CVD joints. This is where the problem really exists, not in a clutch bell bearing.
