So, I never did post the video...
Here it is. Skip a minute or more in for the higher speeds. According to the driver, we got up to 40 mph a few times. Looking back over it, I can't really pick out when those times were (but definitely after the 1:00 minute mark...). I *guess* around the 2 minute mark we are going pretty fast.
Unfortunately, I was being a little conservative and kept adding altitude to avoid trees. I way over did it, and by the end the Solo is up pretty high. If I had kept it lower to the ground, apparent speed would have been greater. None-the-less, you can get a feel for the speed by focusing on how quickly the car moves past trees and driveways on the side of the road.
