That's pretty good! Its really low too. It seems to have pitch problems though...

It seems to have pitch problems though...

Most universal and series-wound motors tend to drop RPM slightly as they warm up, nothing really wrong with that. In any other application you'd probably hardly ever notice the motor do that (if at all), but of course when it's attached to something like a siren rotor, you're going to hear every single tiny speed fluctuation translated as sound pitch variations.

I uploaded the lower view today. It you can hear the clicking of the controls and you can hear the blower itself running. I also added in a clip of the ATI controls at the end.

wow, great quality videos. whatever camera you're using has damn good AGC on the microphone, there was remarkably little audio distortion. I'm guessing it's on chopper level 4, 'cos it sounds almost exactly like the Thunderbolt I recorded some years ago in Harper Woods, MI.

The distant view camera is a Canon Vixia hf r400 and the lower view camera is a JVC Everio

It's pretty cool how on lower view you can hear the controls and the blower!

is this the thunderbolt right by the railroad tracks by downtown in the scrap yard? I pass by it all the time on trains

I do believe that it is.

Looks like the rotor box is starting to become a teeter-totter. :p
