[Brumos RSR]

Hi Graham, 

As you mentioned motors, I found an older style NSR Shark 22 without the screw holes, it preceded the 21.5 EVO

Spec is 22.400rpm - 168 g.cm @ 12V compared to 21.900rpm - 164 g•cm @ 12V

Can I use that?

Basically if I can't measure a motor it does not get onto the list, I have the NSR Shark 20k rpm motors but nothing earlier than that I think, but I will have a look.

We ran Shark22 motors just 2 years ago, prior to Predator 22.5 motors
