How fast are the motors for the TOS Lighting kit?

Here's a half speed video of the fan motors.
I did have some questions on if they were spinning at the same speed and I've done some behinds the scenes trouble shooting. I think part of the issue was the camera and video editing, and it's hard to tell if they were really spinning at different speeds.
So after trouble shooting and double checking some parts, in fact, I sent a motor back to Round2 to have them check it. I wanted to do a controlled test video to see if they were spinning evenly. in about a 20 second video, shown here slowed down to 40 seconds. one spun 17 and 1/8 and one spun 16 3/4 rotations. That should be about 50 and 51 rpm.

I have been following you're videos. Actually you have spurred me onto buying the 1:1000 kits (Enterprise,Reliant,Excellsior)to make. So thanks. I have the Polar lights Enterprise refit 1:350 the good one that came with all the decals etc. But to afraid to start it as my airbrushing skills suck atm. Anyways. enjoy you're videos. And thanks

I was told by Round 2 that the motors were going to be more silent. Have you noticed a difference compared to the previous light kit?

The light sensor chip in your camera is probably what was making it look as if they were off. i was watching one of your vids and it appeared as if one of the fans switched directions and then switched back. seems like a camera issue. Different types of chips can have issues with thin lines in motion particularly from a slight distancing Just a guess

Hey with what kit should i start as beginner?

[@allscaletrek]

Anything moder, the new Voyager is nice, the recent Defiant, or the new Pikerprise.

Still a very audible noise the motor makes
