I think mine are 141:1

Thanks, I bet that's a better gear ratio to use.  I tried giving the motor 9 volts, and 12 volts.  Using 12 volts sped it up to a usable speed, but it was much louder, probably comparable to the little DC motors most people use.  So, if anyone else is thinking about using these motors, I wouldn't recommend the ones I got with the  485:1 gear ratio.

Sorry to hear that. If these motors don't work you might want to contact Ralph at Tena Controls as I hear he sells some nice quiet motors for this kit.

I bought my Faulhabers from many different eBay listings, so now you have me worried that my two motors aren't the same gear ratio (I think I've only been testing each one individually, not both together). Better sort this out before I glue up my other nacelle.

I haven't given up on them, and I will still play around with stepper motors, those are amazingly quiet!

I'll be very interested to know your results with steppers. I found that while they were quiet, the vibration at the TOS E RPM was out-of-control, and that was with micro-stepping.

Here's a quick test I did a few months ago with a 15mm stepper motor....

This explains the vibrations I observed on my stepper: https://youtu.be/ztgX44Pqc18

This is the motor I used in the test....

The motor itself spins pretty fast, eliminating the vibrations, and the gearbox slows it down so it's still pretty smooth.

Excellent! Does it fit in the 1/350 TOS E?

It's too big to fit in the motor housing, but there is plenty of room to mount it behind, like you did your Faulhaber motors.  The only issue is you need something to drive the motor.  I've played with an arduino and driver board (https://www.ebay.com/itm/New-L9110S-H-bridge-Dual-DC-Stepper-Motor-Driver-Controller-Board-for-Arduino-/181307927681?hash=item2a36cb6c81), which is what I used in the video, and I've tried one of these gizmos....

The only issue with the latter is that it's too big to fit inside the nacelle, so I'll have to run 4 wires up the nacelle struts to power the motor if I decide to use it.

Excellent. If you go the stepper route, I would love to see what you come up with.

That might work very well for my 1/650 scale TOS Enterprise.  The size and sound level look good.  How was the vibration level with the 15mm motor?

Have you seen this driver board?  https://www.amazon.com/Hobbypower-StepStick-Stepper-Driver-Printer/dp/B00MQR93QC

Here is a YouTube showing it with an Arduino hook-up: https://www.youtube.com/watch?v=GgfgWU0bpHk

I used a similar setup for my test (see my YT video posted above) but at the desired RPM the vibrations were so great I think it would tear the ship apart.

In the video he says he's new to the A4988 stepper board so he doesn't do anything with the trim pot on it, which from my experience is crucial. You have to set the current limit on the board with a multimeter using your desired power supplies and steppers to ensure you don't wreck the motors. I found it very confusing but I seem to remember the Polulu people posted a great video tutorial about their A4988 which be helpful: https://youtu.be/89BHS9hfSUk

Hi Ross, I'm trying to put together the main board and I'm having trouble finding which capacitor goes in the C7 spot on the back of the board.  I don't see it on your parts list, but I can see something is installed there on your photos.
