VPI Motor Upgrade Kit

I am running the new 300 RPM from VPI as part of the upgrade on my Scout to Scoutmaster. Speed is far more consistant so far. It's only been a week and the motor control is also being handled by a Walker Precision Motor Controller too. The pulley system is more robust and VPI is using a new material "black belt" which eliminates the bumpy seam that was in the older clear belt.

would there be any need/benefit upgrading to the 300 rpm if im already using an sds?

Depends on which of the three tables you mention you are refering to. I know that some early Scouts reported noisy/vibration prone motors. To my mind the addition of the SDS or Walker motor controller benfits ANY motor running on it. Provides clean stable AC as well as an easy way to switch between 45 and 33 RPM.

im running a scout, a later model, and really happy with what the sds has added. but of course, im wondering if the 300 rpm would provide any added benefit. is there anyone who has just done the motor upgrade with a scout and sds can comment?

thanks

Second what Photon46 said. That's a good summary.

Several months ago HW offered to ship me a 300rpm motor to A/B on my Teres and post a review. That would have been fun and I accepted. It hasn't arrived yet, so I presume VPI's been busy making stuff for real customers.
