Jeff- Yep...those lids were my crutch while I was beginning to fly my Helicycle. I fiigured as long as I am over those lids.....the trees flanking me wont be chewed on by my rotor!
I dont even look at the lids now......and actually many have had grass encroach over them and some have been dug up by animals....then my mower has hit a few.
The GoPro image makes the channel look a little narrower than it is. It actually averages 60-65 feet wide,....and I have roughly a 21 foot rotor.
If I am that sloppy that I wonder off the centerline of that chopper channel over 20 feet.....then I deserve whatever tree my rotor finds! ha
